[[caption-width-right:350:Because nothing stops a guy like ''[[MindRape hijacking his mind]] via a brain port...'']]

In many CyberPunk works and occasionally other sci-fi, technology is typically very advanced. Since convenience is highest priority and TheSingularity is looming, it's natural to assume that the next big thing thing is [[BodyHorror embedding cables into your skull]] [[{{Transhuman}} and synching your brain with a computer]]; since a keyboard or mouse can be cumbersome and slower than human thought, it's natural to assume that implants, headbands or helmets will be next to hit the shelves.

Of course, this frequently comes with the benefits and risks of computers albeit inside a person, so expect [[BrainUploading human backups]], [[NeuralImplanting self-enhancement]], [[MindControlDevice life hacking]], [[MindVirus people viruses]], and MindRape among other things. Actual physical jacks are rapidly approaching {{Zeerust}} status nowadays as the heretofore insuperable complications of physical penetrations through the skin seem more and more like unnecessary risks in a world rapidly moving towards wireless solutions.

In many cases, especially when physical jacks are involved, having such an interface will be the mark of an [[HollywoodHacking elite hacker]], or of certain specific professions, such as [[CyborgHelmsman starship pilot]]. In a few cases, the use of such interfaces may be limited to cyborgs or aliens or the [[GeneticEngineeringIsTheNewNuke genetically engineered.]] If ''everyone'' has one, there's a good chance you're looking at a MindControlDevice or even an artificial HiveMind.

Sub-trope of UnusualUserInterface. See ElectronicTelepathy if it has wireless capability. Not to be confused with, though frequently used for, NeuralImplanting, which is where data or skills are inserted into a person's brain.


[[folder: Anime and Manga]]
* In ''Franchise/GhostInTheShell'', a number of characters, including the Major, have ports implanted onto their bodies, typically at the back of the lower neck / upper shoulders that allow a direct connection between the brain and virtual reality; Batou and Ishikawa both use said ports to ''[[MindRape override movement through the brain and temporarily disable people]]''. In the ''Stand Alone Complex'' series, we get a glimpse of what the internet looks like from within.
** The external ports are part of what the series refers to as a cyber-brain, a complex series of interfaces connecting directly to the brain. The external ports are mostly used for high bandwith and/or more secure connections while virtually every character has a wireless connection as well. The sheer ubiquity of the technology, at least in Japan, is what makes skilled hackers like the Puppetmaster, the Laughing Man or the Major herself so potentially dangerous.
* ''Franchise/{{Gundam}}'' shows taking place in the Universal Century have the Quasi-Psycommu system, which was meant to allow a normal human being to mimic the ElectronicTelepathy of the standard Psycommu, which required a Newtype to use. It was partially successful, allowing normal humans to thought control wire-guided AttackDrones, but very inefficient and unstable, meaning it was ultimately scrapped.
** ''Anime/MobileSuitGundamWing'' has the ZERO System, which feeds data directly into the pilot's brain and reacts to his decisions practically at speed-of-thought. Unfortunately, if you don't have immaculate focus, it drives you crazy.
** ''Anime/MobileSuitGundamIronBloodedOrphans'' features the Ālaya-Vijñāna System, [[BodyHorror spinal implants]] that allow the user to connect directly with a mobile suit to improve reaction time and spatial awareness. Due to the nature of the procedure, they can only be implanted in [[ChildSoldiers growing children]], and the procedure has a high rate of failure, generally resulting in spinal injuries, para- or quadriplegia, or even death. While the implants are severely taboo on Earth (to the point where most people treat those with implants as if they aren't even human anymore), less ethical groups like the [[PrivateMilitaryContractors Chryse Guard Security]] and [[SpacePirates Brewers]] will "adopt" kids and force them to undergo the surgery, abandoning them on the streets if the process fails. [[spoiler:In the climax of the first season, after Ein Dalton's body is mangled beyond repair by Mikazuki, he agrees to a procedure that hooks his brain directly into a SuperPrototype dubbed the "Graze Ein", meaning he effectively '''is''' the Mobile Suit.]]
*** The show goes on to reveal that there are significant limiters in place to protect the pilot's brain, but this is seemingly dependent on the user; in one episode, Mikazuki's default settings for the Barbatos are so high that when another member of Tekkadan tries to pilot the machine it overloads his brain and renders him temporarily comatose. [[spoiler:Three times during the series (versus the Graze Ein, versus the Hashmal, and during the final battle), Mikazuki deliberately disables the limiters to get maximum performance out of the Barbatos, which results in his losing the use of parts of his body (his right eye and arm the first time, his right leg the second time) though when he's hooked into the system they function just fine. In the last instance he overclocks the system when he's already mortally wounded, meaning his Gundam seemingly keeps fighting for a few minutes before his enemies cut open the cockpit and realize that he's already dead.]]
*** The second season introduces a couple of variations on this: [[spoiler:[=McGillis=] Fareed used the data gathered from Ein Dalton's procedure to get an A-V implant despite the fact that he's an adult, letting him pilot Gjallarhorn's "sword in the stone" Gundam Bael. Meanwhile, Gaelio Baudin had Ein's brain[[note]]It's unclear if he means the actual brain matter or a computer copy of it[[/note]] installed into his pilot suit, allowing him to hand over control of his Gundam to Ein; this version is officially dubbed "Ālaya-Vijñāna System Type-E".]]
* ''Anime/MartianSuccessorNadesico'' achieves this effect with {{Nanomachines}} allowing the pilot to interface directly with the mecha. These are also the control medium for larger military vehicles and a lot of civilian equipment in the Martian colonies. For once, there are no major downsides (it's the ''other'' {{nanomachines}} you have to look out for), and it is in fact relatively easy to get the nanomachine injection if you're already in the military.
* In ''Anime/NeonGenesisEvangelion'', the Eva units are controlled with a direct neural interface with their pilots, via the LCL and the A10 nerve clips (those joysticks are just for fine manipulation and weapons control which are properly not even necessary with a high enough sync-rate). Side effects may include [[{{Synchronization}} sympathetic pain and injuries in direct proportion to the synchro-rate]], the Evas going into sudden [[UnstoppableRage unstoppable rampages]], being a helplessly immobile and vulnerable sitting duck at very low synchro-rates, or total [[MemeticMutation tangification]] due to a ''very high'' synchro-rate. Reasons #527, 528, and 529 why it sucks to be an Eva pilot.
* Lain gets a direct neural interface in ''Anime/SerialExperimentsLain'': she plugs herself to her Navi by sticking electrodes on her body and plugging them into the USB ports.
* Multiple variants appear in the ''LightNovel/SwordArtOnline'' / ''LightNovel/AccelWorld'' universe.
** [=NerveGears=] are bulky, head-concealing helmets that use some kind of microwave transmitter to intercept signals between the brain and the body, providing the user with a perfect virtual reality environment in a process called [=FullDive=]. First appeared in 2022.
** [=AmuSpheres=] are visor-like devices that are essentially a far more compact [=NerveGear=] with significant improvements in user safety. For that reason, the two are fully inter-compatible. Appeared sometime during 2023.
** Brain Implant Chips are small devices permanently installed beneath the dura mater. They were the first devices to feature AugmentedReality in the form of an UnusualUserInterface where the user uses hand gestures to manipulate interface elements only he can see but are also illegal due to the risk of brain hacking and exam cheating. [[spoiler:It also hides the user from Brain Burst matching lists but at a cost: if BB is uninstalled, the chip dissolves into the cerebrospinal fluid.]]
** The [=NeuroLinker=] is the legal successor of the BIC: a small, choker-like device worn around the neck that provides both AugmentedReality and [=FullDive=]. Unlike the BIC, [=NeuroLinkers=] are completely non-invasive and can be taken off with no ill effects. Completely ubiquitous by 2046.
* ''Anime/{{Macross}}'':
** One of these was part of the prototype YF-21 "Sturmvogel" in ''Anime/MacrossPlus''. The BCI was found to be incompatible with the test pilot and had a tendency to pick up stray thoughts, so the design was scrapped. The production model VF-22 "Sturmvogel II" lacks any such system.
** ''Anime/MacrossFrontier'': The VF-27 "Lucifer"-class fighters have a thought-controlled interface for use by cyborg pilots. Non-augmented pilots can still use standard controls, but they aren't as efficient.
* In ''Anime/FutureGPXCyberFormula'' the [[spoiler:Al-Zard NP-1 is a bio-computer that helps its pilot drive better by basically controlling his every action.]]
* In ''Anime/{{Robotech}}'' and the source material for the second saga (namely ‘‘Anime/SuperDimensionCavalrySouthernCross’’) this is one of the reasons the Bioroid are so hard to take down: being thought-controlled they’re far more nimble than the human mechs they’re facing, and the multiple redundancies in the system mean the only swift way to take one down is SnipingTheCockpit.
** In Jack [=McKinney=]’s tie-in novels Earth mecha have a similar system, the Thinking Cap. Said system is not present in the series, as shown in all sagas (where the control systems are seen multiple times) and outright stated in the second saga (when the traditional controls are contrasted with the Bioroid’s).

[[folder:Comic Books]]
* Cyberjack-style interfaces are common in Carla Speed [=McNeil=]'s ''ComicBook/{{Finder}}'' series, and vary in complexity, from student-level jacks to full-immersion interfaces. Marcie's student jack makes it for medical computers to directly monitor her condition and influence her treatment. She can also use it to interface with computers, mentally conduct Instant Message conversations and learn skills quickly (albeit unpleasantly; Marcie [[http://www.lightspeedpress.com/index.php?module=Finder&func=pub&issue=19&page=22 runs away screaming]] when Lynne offers to teach her to read via hookup.) Movie theaters take advantage of this by including sensory enhancements and "mood tracks". In the Dream Sequence storyline, the narrator has a full-immersion connection as a job perk, which allows his employer to [[http://www.lightspeedpress.com/index.php?module=Finder&func=pub&issue=23&page=11 physically pack employees like sardines,]] while they experience a [[http://www.lightspeedpress.com/index.php?module=Finder&func=pub&issue=23&page=12 lush virtual office setting.]] The plot revolves around a virtual theme park/MMORPG whose creator hosts the world inside his fully-networked brain (which, of course, [[GoneHorriblyWrong goes horribly wrong]]).
* Dynamo Joe had Data Com One, a paraplegic whose brain was linked to a military computer, making him a brilliant strategist.
* In Franchise/{{Superman}} continuities where ComicBook/{{Brainiac}} isn't a robot himself, this is what the diodes on his head are used for.
* ''ComicBook/{{Transmetropolitan}}'' has a "phone trait" that uses an imaginary keyboard, one time Spider uses his to transfer some incriminating photos over the phone lines.

* In ''Fanfic/TiberiumWars'', the Nod Avatars are presented as having a powerful mind/machine interface, with the pilot existing in a sort of dream-like state where the operator shares operations with a cold, mechanical AI intelligence that helps them perceive their surroundings, which comes in as a constant stream of pure data and filtered into an alternate virtual reality for the pilot.
* In ''Fanfic/MassEffectEndOfDays'', this is an integral part of Alliance society. The Council finds the extent of the use of it... disturbing.

[[folder:{{Animated Film}}]]
* ''Film/{{Big Hero 6}}'' has the microbots being controlled by a headband neural interface, which Yokai incorporated into his kabuki mask.

* ''Film/{{eXistenZ}}'' has biological computers which interface with you through plugging a ''very phallic'' tentacle into a port in the base of your spine. The movie plays this for all it's worth, even having characters lick the ports of other characters during sex scenes.
* ''Franchise/TheMatrix'' has every human used by the machines outfitted with a port in the back of the skull to plug into the matrix. In Zion, humans with the port are plugged into a machine that... apparently lets them manipulate a huge 3-D computer interface. Non-vat grown humans can't get one installed, either. This means that natives of Zion, or in other words the grown up children of Matrix escapees, have to content themselves with either flying the hovercraft, or playing "Operator", which means plugging people into the Matrix, getting them out, and giving them weaponry while they're in there. Well, in theory they could give them anything, but it's often [[MoreDakka guns. Lots of guns.]]
* The movie ''Film/SleepDealer'' uses this frequently and most people work by controlling machines through brain computer interfaces.
* In ''Film/StrangeDays'' virtual reality is someone else's reality. Using computerized Walkmen that record and play back thoughts and sensations, voyeurs relive parts of other people's lives--sometimes with deadly results. The walkmen operate using a brain computer interface.
* ''Film/{{Upldr}}'' has the protagonist working to develop this technology that enables people to upload or download brains.
* In ''Film/{{Saturn3}}'', brain stem interfaces are placed in all human "instructors" of the Demi-god series of robots, allowing direct connection via radio waves (precursor to bluetooth) to upload instructions/training. Apparently, they are kept in those who wash out of the training program, allowing the insane Captain Benson (Harvey Keitel) to take the place of the legitimate operator. As a result, the robot Hector, whose brain consists of living tissue, takes on his insanity, and lust for Alex, Farrah Fawcett's character. Later, Hector kills Benson and implants the interface in Alex's partner, Adam (Kirk Douglass), not to put anything into his head, ''but to take something out.''

* The LINK, in ''Literature/ArchangelProtocol''. The LINK brain implant is done at birth, and gives access to the VR internet, or LINK, when it is activated at 18. And, of course, it is permanently disabled if a person is excommunicated or an atheist. All commerce and communication is done via the LINK, and once cut off, the last recourse is [=MouseNET=], the hacker Mouse's ''free'' part of the LINK, and what remains of the old, unregulated internet. Comparatively low in bandwidth compared to the rest of the LINK, Russia's entire economy runs via [=MouseNET=].
* ''Literature/{{Neuromancer}}'' practically invented this trope, especially as regards the {{Cyberpunk}} genre.
* ''{{Literature/Valhalla}}'' includes brain linked internet very much in the spirit of Neuromancer or ''Franchise/GhostInTheShell''.
* Telepathy runs computers in Literature/TheCulture.
** Plus the mental images used to control the biological implants and drug glands.
* An ex-military space pilot in Katherine Kerr's ''Polar City Blues'' had a (sealed over) port in her head from interfacing with the ships she flew.
* Michael Scott's ''Gemini Game'' features the standard "big plug on the back of the neck" and headband-based videogame ports.
* In Creator/TimothyZahn's ''Literature/TheConquerorsTrilogy'' (''Conqueror's Pride'', ''Conqueror's Heritage'', and ''Conqueror's Legacy''), the [[CoolPlane Copperheads]] were controlled through a jack in the back of the heads of the pilot and tail gunner, with the interface basically mapping the fighter's functions to a virtual human body. Damage is represented by pain, weapons by the user's fists, and so forth.
* In Scott Westerfeld's ''Literature/{{Uglies}}'' series, the Specials have this, as well as in the fourth book, ''Extras''. In ''Extras'', everyone has these.
* Creator/SamuelRDelany's ''Literature/{{Nova}}'', published in 1968, featured a technology in which people had neural wrist- and neck-plugs installed so that they could control a wide variety of gadgets, from vacuum cleaners to starships. This style of interface was so pervasive that individuals who did not want to receive the implants were effectively unable to use any remotely sophisticated equipment.
* The Creator/DeanKoontz novel ''Midnight'' featured people who were mutating in bizarre ways. A 'popular' mutation was growing a computer interface, and when one such person died the computer freaked out and started 'screaming' about missing the rest of it. Another person melded with his car in a similar way.
* In the later ''Literature/{{Foundation}}'' books by Creator/IsaacAsimov some ships are flown by neural interface.
* ''Psychohistorical Crisis'' by Donald Kingsbury is set in a future that's inspired by Asimov's ''Foundation'' series, re-imagined for the 1990s. Brain-computer interfaces are ubiquitous, and are used to explain several phenomena that Asimov attributed to PsychicPowers.
* ''Literature/TheHitchhikersGuideToTheGalaxy''. Infinidum Enterprise's Computer Terminals in the Hitchhiker's Guide buildings. There is a quote explaining how they're not a 'clunky typewrighter in front of a television set', but in fact a brain-computer interface thing.
* ''Call me Joe'' is about a disabled man who controls life forms on Jupiter using such an interface.
* ''Literature/{{Animorphs}}'' has these on the bug fighters and other alien craft. Ax makes a comment about human computers being so primitive they don't have a decent psychic link.
* Required for the hand less [[SapientCetaceans neo-fins]] to use tools in the ''Literature/{{Uplift}}'' series, usually linked to a harness with prosthetic arms and other tools, though they also use them to control vehicles and fly spaceships. Many humans have similar sockets for similar reasons. The book is also a primer on the risks of such interfaces with one character suffering brain damage from electrocution through their socket and another physical injury when an interface plug is forcibly yanked out in an ultralight airplane crash.
* A key plot point in Brain Jack, by Brian Falkner. Comes in the form of "Neuro Headsets".
* Such interfaces are noted in passing in ''Literature/AFireUponTheDeep''. They don't work very well below the High Beyond, but their users still don't like taking them off.
* Most humans are fitted with a neural implant at birth in ''Literature/TheHistoryOfTheGalaxy'', which is used to translate thoughts into wireless signals. Mainly used for identification and appliance control. Some people voluntarily (and some not so voluntarily) undergo implantation of additional implants that, effectively, turn them into [[TheCracker hackers]] that don't need a computer. They can even access a person's neural implant and fry his or her brain. Want to use a gun on them? Better use an ancient one that shoot bullets and has no electronics. Regular EM guns with computer chips inexplicably stop working when faced with a "cybreaker". Also used to enter virtual reality.
** There is also a colony of humans founded by those who have been subjects of genetic experimentation and have additional glands that emit and receive infrared signals that interface with any device that has an IR port (in this 'verse, nearly all computers have one). This is the biological version of a neural implant.
** A more direct approach involves plugging a cable into a port in one's temple, which people get at the same time as the implant. The port is normally covered by false skin.
* In George Alec Effinger's ''Literature/MaridAudran'' series, this is mainly used with the customized portable devices called "moddies" (personality overlays used for entertainment) and "daddies" (add-ons that provide specific skills, like languages or technical expertise). Many people have sockets in their head for at least one moddy and a couple of daddies. The sockets can also be connected to more general-purpose computers and multi-player video games.
* Renos in ''{{Literature/Aristoi}}'', which partially inspired the mesh inserts in ''TabletopGame/EclipsePhase''.
* This is what the titular Nexus 5 does for a human in ''Literature/TheNexusSeries''. Nexus allows nanomachines to bind to the human brain and map itself into a usable architecture during a psychedelic [[FantasticDrug "calibration phase".]] Afterwards, anyone running nexus can communicate entire emotions, ideas, and memories to anyone else with the architecture. This doesn't even touch on what happens if someone has a [[PeoplePuppets back-door.]]
* In ''Literature/HeartOfSteel'', {{cyborg}} Alistair Mechanus has a mental interface with his island's computer network through his cybernetic implants. However, he can't access it without the A.I. Arthur, as he discovers when Arthur is taken out.
* The Bremen Chip from ''Literature/{{MARZENA}}'' is inserted via the nasal cavity into the thalamus (the processor of the senses and the origin point of consciousness) and allows its users to connect wirelessly to computers, or even to merge minds with G-Net AIs or people who who also had the chip implanted. Communication between two brains can be tricky though and usually requires a middle brain for the translation of brain activities (unless they are identical).
* In the ''Literature/RevelationSpaceSeries'', brain-computer interfaces ''used'' to be common, but then the Melding Plague GreyGoo showed up and [[LostTechnology ruined everything]]. The Gunnery interface on the ''Nostalgia For Infinity'' requires implants that makes the user visualize themselves as the 4 kilometer long starship when sitting in the Gunnery control chair.
* ''Literature/TheStarchildTrilogy'' has a very early example (from two decades before {{Cyberpunk}} became a thing). Unusually located directly on the forehead, "communion plates" are how the most advanced technicians work with the [[MasterComputer Planning Computer]].
* ''Literature/{{Incarceron}}'' has the Glove, which allows one of the characters to pull a GrandTheftMe on the artificial intelligence it interfaces with.
* Catherine Fisher likes this trope. ''Literature/RelicMaster'' also includes the Coronet, which jacks the user's brain into the [[WeatherControlMachine Weather Control Machines]].
* Agent G and all the other CorporateSamurai ProfessionalKiller types in the International Refugee Society have this as part of their standard cybernetics package. It's implied to be fairly basic tech in the ''Literature/AgentG'' world.

* The skin of the advanced Cylons in the new ''Series/{{Battlestar Galactica|2003}}'' is light-sensitive. If they have to use primitive fiber-optic cables, they can (painfully) insert that cable into their forearm to interface with computers (but they have to [[{{Squick}} make an incision first)]]. Typically, on their own ships, they can interface with their own ships by putting their hands in a stream of luminous water called the "datastream". It's unclear if there are electrical or biochemical transmitters to go with the light-based data connection, but it [[RuleOfCool sure looks cool]], especially with nearby displays that [[MatrixRainingCode show oddly familiar data glyphs in a falling pattern]]. It helps that they're {{Artificial Human}}s.
* ''Series/DoctorWho'' episode "The Long Game" had people installing ports in their foreheads.
* In ''Series/StargateSG1'', human-form replicators can interface with technology (particularly Earth computers) by sticking a body part, usually a hand, directly into the machine. Apparently this also works on humans, as the human-form replicators can literally get inside their victim's heads (though it is [[MindRape not exactly painless for the victim]]).
* In ''Series/StargateAtlantis,'' a lot of Ancient and Wraith technology is operated by thinking at it.
** Unfortunately, no matter how much you think at it, a Puddle Jumper won't make you a sandwich.
* On ''Series/StarTrekDeepSpaceNine'', certain members of the [[TheSyndicate Orion Syndicate]] have implants that allow them to hack into computer accounts. The risk is that they can be rather easily "spiked" if the hacker is caught, causing painful and potentially lethal feedback.
* In the ''Series/StarTrekVoyager'' finale, Janeway returns from decades in the future to change the present, and she is implanted with a standard issue neural computer interface from the future.
** There's another episode where Tom Paris gets too close to an alien shuttle with a neural interface.
* In ''Series/{{Andromeda}}'', Seamus Harper had a dataport in the side of his neck, which allowed him to plug into, and interface with computer systems.
** Later on, he plugs a tesseract into the same port, which allows him to pass through solid objects.
* In ''Series/RedDwarf'', in a TV episode and expanded for the novelisation, the computer game "Better Than Life" works on this principle - terminally addictive total virtual reality
* ''Series/LookAroundYou'' (series 1) parodies this with [=EBEs=], Electronic Brain Enhancements, chips that students can plug into their heads to help with their revision but which they can become addicted to.
* The entire premise of ''Series/{{Intelligence|2014}}'' is that US Cyber Command has installed a wireless-enabled computer chip in Gabriel Vaughn, a former Delta Force operator, to create "the next generation of [[TitleDrop intelligence]]."
* In ''Series/{{Farscape}}'', unlike normal [[LivingShip Leviathans]], Talyn is designed to implant a [[HumanAliens Peacekeeper]] pilot with an implant in the base of the neck that connects their nervous systems wirelessly.
* An extremely primitive example compared to most, but Root gains one of these in ''Series/PersonOfInterest''. After an involuntary stapectomy, she gets a Cochlear implant that serves as a constant link to The Machine.

* In ''Synchronize'' by Music/MindInABox, an inventor is building a mind-computer interface which works through the bloodstream in order to access [[{{Cyberspace}} The Dreamweb]]. The Agency likewise has built its own machine in ''[=5ynchro0ni7e=]'' to destroy the Dreamweb, using expendable test subjects to attempt to access it - with [[YourHeadAsplode explosive and bloody results]] - not realizing that the music of mind.in.a.box is the key to synchronizing with it. The Agency machine is described as pumping the test subjects full of a cryogenic compound.

* In Creator/{{Bally}}'s ''Pinball/{{Xenon}}'', people plug wires into jacks in their heads to interface with the titular supercomputer.

* ''TabletopGame/{{Shadowrun}}'' and nearly every work of CyberPunk has the datajack, a port or wire usually somewhere on the side of the head to hook up to a computer. A cyberpunk character who can't "jack in" with a port in their head is not trying hard enough.
** Later games, however, have caught up with [=WiFi=] and made wireless the prime mode of interaction with the Internet. People still have ports in their head that connect to the web, they just don't require the cables.
** ''TabletopGame/{{Cyberpunk}}'', at least, this includes the possibility of using chips to know abilities you don't know. However, its just useful to be a [[JackofAllTrades Jack of All Trades]].
* ''TabletopGame/{{Warhammer 40000}}'':
** Most vehicles and war machines are plugged directly into the pilot's brain, in a rather low-tech way.
** The BioAugmentation process that turns ordinary men into Space Marines involves implanting a lot of extra organs. One of the most important ones is the Black Carapace. The Black Carapace is the interface between Space Marines and their iconic suits of PoweredArmor.
* ''TabletopGame/EclipsePhase'':
** Nearly all Morphs come standard with Basic Mesh Inserts (the Mesh being the post-Singularity version of the 'net).
** The Access Jacks implant, which allows users to hook their brain to machines via fiberoptic cable, if you prefer your connection faster and impossible to intercept.
* ''TabletopGame/CthulhuTech'': Engels. See ''Anime/NeonGenesisEvangelion'' above, without the {{synchronization}}, but with more invasive surgery and SAN checks.
* TabletopGame/{{GURPS}} ''TabletopGame/TranshumanSpace'' makes brain implants practically the only cybernetics still in common use.
* Iron Crown Enterprises' Cyberspace. The Direct Neural Interface implant allows a person's brain to be hooked up to computers (such as a C Deck) with a DNI Cable.
* R. Talsorian Games' TabletopGame/{{Cyberpunk}}. Interface Plugs allow the person implanted with them to connect to and control cyberdecks.
* ''TabletopGame/{{Alternity}}'' has an implant that allows a character to interact with compatible technology.
* Present in ''TabletopGame/BattleTech''. Enhanced Imaging and the Direct Neural Interface are implants which basically allows the pilot to directly control the [[HumongousMecha BattleMech]] with their mind, rather than with the standard joysticks and neuro-helmet. Protomechs all use this, as they're too small to fit a cockpit. The devices have a number of drawbacks, such as crippling withdrawal symptoms and causing the pilot to go slowly insane. For standard issue control interfaces in [=BattleMechs=], however, the ubiquitous Neurohelmet is used, albeit only to balance the mech. Instead of invasive neurosurgery, all the neurohelmet requires is a clean haircut around the temples and a tolerance for a scalp-crawling sensation. Depending on the technological capacity of the time period that a neurohelmet was manufactured, neurohelmets can range from something the size of a real-life fighter helmet to giant bulky crude 10 pound monstrosities.
* The Neural Connectivity Suite in ''TabletopGame/HcSvntDracones'' replaces the user's cranium with a wireless computer that is capable of running various software and enables "telepathic" communication. Along with upgrades like a wireless hub (that can intercept and redirect radio signals), or a [[HiveMind hive node]]. [[RidiculouslyHumanRobots Cogs]] can interface with machines by touching them but have no wireless capability without an NCS, and their Core Consciousnesses work sufficiently different from normal computers that they can't run software either.
* In ''TabletopGame/RocketAge'' the Ancient Martians used neural interfaces to interact with their war-walkers (something the Nazis have been quick to reverse engineer) and the Europans, the setting's most advanced race, have also developed something similar.

* VideoGame/DeusEx mentions an occipital [[note]]bone in the back of the skull, and the brain lobe beneath it[[/note]] jack in one in game news article and an in game email. Based on the context of the news article (the fact that a teenage girl has one is mentioned alongside having a tattoo and wearing black), these are looked upon negatively.
** Early in ''VideoGame/DeusExHumanRevolution'' you encounter a "Purist" hacker with a "neural hub". The fact that an anti-aug terrorist has wires sticking out of his skull is one of the first major hints that something is up. Panchaea's supercomputer requires a set of spinal implants [[spoiler: as possessed by Zhao Yun Ru and the [[WetwareCPU Hyron Drones powering it]]]] to be directly accessed.
** In ''VideoGame/DeusExMankindDivided'', investing Praxis into your Hacking skill tree upgrades Jensen's own neural interface, allowing it to use increasingly large parts of his brain for extra processing power when attacking "secure" devices.
* Pretty much the entire point of the ''VideoGame/HalfLife2'' mod ''VideoGame/{{Dystopia}}''. The players can jack into a 3D interpretation of a computer by mentally connecting to the computer through the cyberdeck in their heads. Of course, since they are putting their own minds inside the machine, they leave their real bodies vulnerable to attack.
* In ''VideoGame/BeneathASteelSky'', Robert Foster has to enter LINC Space via a surgically implanted Schreibmann port in the back of his head, in order to operate the LINC interface, which is essentially a chair with a huge cylindrical visor that drops down to link up with the user.
* In ''VideoGame/EVEOnline'', players fly their ships by being inside a pod full of goo with a neural interface which connects to the ship's systems and can easily be transferred between ships as well as ejected in the case of the ship's destruction (and if it is destroyed, a neural scan allows the player's mind to be transferred to a clone maintained at a station to cheat death). The interface allows a single person to control all of the ship's systems on any ship from a shuttle to a 20km long titan, with much faster reactions and better control than a human crew manually controlling it could have (NPC ships are controlled by crews, and with the exception of CONCORD, are relatively weak).
** There is debate about whether ships flown by pod pilots actually have any crew at all or have completely automated systems, but it is normally accepted that smaller ships have none, while large ships have significantly smaller crews than would be needed without a pod pilot.
** One of the Chronicles confirms that a Apocalypse battleship has over two thousand crew who go down with the ship.
* The pilots in ''VideoGame/{{Implosion}}'' use a neural link to download their minds into their [=WarMech=]s. The in-game explanation is that since the pilots aren't physically inside their battle suits, they're immune to viral infection from the alien XADA enemies. Too bad the XADA eventually figure out how to hack the link.
* ''VideoGame/SystemShock''. It actually makes sense from the player's perspective.
* The Dreamer consoles in ''VideoGame/DreamfallTheLongestJourney''.
* ''Franchise/{{Halo}}'':
** All members of the UNSC Armed Forces are equipped with [[http://www.halopedia.org/Neural_interface a neural interface]] in the back of their skulls, primarily used for Identify: Friend/Foe purposes and HelmetMountedSight integration, but also for data storage/networking. Additionally, advanced training simulators can feed simulated sensory inputs into their participants' neural interfaces to make their training scenarios more authentic.
*** Ship commanders such as Captain Jacob Keyes, meanwhile, have [[http://www.halopedia.org/Command_neural_interface command neural interfaces]] for specialized information involved in their command. This becomes a major plot point in [[VideoGame/HaloCombatEvolved the first game]] and particularly its novelization ''[[Literature/HaloTheFlood The Flood]]'', [[spoiler:because this is how the Flood tried to lift the location of Earth from Keyes when they couldn't get it out of him directly]].
*** Through a [[http://www.halopedia.org/Spartan_neural_interface Spartan neural interface]], Cortana increased the Master Chief's compatibility with his [[PoweredArmor MJOLNIR armor]], and can have further access to his suit's systems. This is also for the most part how the MJOLNIR armor works in the first place, with the user moving the armor's limbs via thought (though it still requires {{Super Soldier}}s like the Spartans to wear and make use of it - regular soldiers who tested the initial versions of the armor essentially pasted themselves because the armor moved too fast).
** The personal armor worn by all [[{{Precursors}} Forerunners]] includes a neurally-integrated computer system.
* In ''VideoGame/MassEffect2'', the ''Overlord'' system is a horrific example of this. [[spoiler:In desperation, the lead scientist hooked up his autistic brother into the computer's mainframe, which drove him half insane in the process. Those repeated static burst you hear? It's him screaming, "'''Please! Make it stop!'''"]]
** In ''VideoGame/MassEffect3'', the Geth use similar technology to allow Shepard to enter the Geth consensus, in order to de-bug the Reaper code that's infected their systems.
* Near the end of ''VideoGame/{{Machinarium}}'', you have to connect your brain with that of the huge-headed leader. You view his mind as a tiny-screened 8-bit game, with the objective of shooting out 33 viruses that were planted by one of the villains. Of course, EVERYONE'S a robot in this game.
* Having one of these installed is a requirement for becoming [[WetwareCPU Un]][[SapientShip bound]] in the ''VideoGame/{{Homeworld}}'' universe. MindRape and [[AndIMustScream worse]] is still a threat posed by a few sources, from [[TheVirus the Beast]] to [[spoiler:quite possibly the Taiidan Emperor]].
* ''VideoGame/AceCombat3Electrosphere'' has aircraft controlled in this manner, through an ENSI (Electro-Neuron-Synapse-Interface) that replaces the standard stick and throttle to allow the user to control the plane with their thoughts. The SuperPrototype X-49 Night Raven uses an "Opto-Neuron-Synapse-Interface" instead, which requires some surgery on the user to connect first, and which artificially accelerates the brain's neural network to allow for greater combat performance, at the cost of increased mental strain on the user that can lead to brain damage. The system as a whole is known as [[FunWithAcronyms COFFIN, or Connection for Flight Interface]].

* From ''Webcomic/GirlGenius'', The Throne of Faustus Heterodyne. [[http://www.girlgeniusonline.com/comic.php?date=20071005 It can]] be [[http://www.girlgeniusonline.com/comic.php?date=20071008 reasonably described]] as [[http://www.girlgeniusonline.com/comic.php?date=20071029 creepy.]]
* The CoolCar driven by ''Webcomic/GeneCatlow'' and Catswhisker can be driven normally... or by ''thought''. The latter method, however, proves difficult to operate.
* ''Webcomic/{{Terinu}}'' has the old "port in the head" method of cybernetic interface, but it's limited to expensive and specialized "Cybergliders" who run the risk of eventual brain damage even before you add in encountering hostile ICE. Everyone else sticks to either voice commands or keyboards.
* Kimiko Ross from ''Webcomic/DresdenCodak'' has a jack in her upper back.
* ''Webcomic/{{xkcd}}'' shows us that [[http://www.xkcd.com/644/ some people]] are not going to wait for these interfaces to go mainstream.
* Bedivere in the Space Arc of ''Webcomic/ArthurKingOfTimeAndSpace'' has an I/O jack replacing [[strike:her]] his [[ArtificialLimbs missing hand]]. [[http://www.arthurkingoftimeandspace.com/1065.htm Largely for the sake of a pun.]]
* In ''Webcomic/TwentyFirstCenturyFox'' most personal computers are VR glasses that seem to respond to a combination of brain signals and voice control, offering a full sensory experience. While cyborgs may have a cortical jack. The same technology is later used for "o-Pods" that act as a virtual reality version of the iPod.
* In ''Webcomic/UmlautHouse 2'' most people have "Eye-fis".
* Occipital computers ("Ocks") are uncommon in ''Webcomic/EscapeFromTerra'', they can also get a [[SubspaceAnsible tangle-net]] upgrade.
* Implants are fairly common in ''Webcomic/QuantumVibe'', though Beltapes typically don't get them as they were once enslaved using them. Nicole got hers in order to [[NeuralImplanting download the basic skills to pilot a Helio-flyer]], and notably jacked it into her flyer when a solar flare fried the normal controls.
* In ''Webcomic/NotAVillain'', Kleya uses a sophisticated brain-computer interface, but disguises it to conceal her identity.
* ''Webcomic/{{Magience}}'' uses a “neuron entrainment” headset. It works even when the user is asleep.
* ''Webcomic/{{Pilot}}'': Robots are able to do this, allowing them to multitask. The titular Pilot uses it to both fly a plane and talk with passengers on the way.
* In ''Webcomic/{{SSDD}}'' Tessa's squad have nanobot implants that are primarily used for ElectronicTelepathy, though they can interface with some compatible technology such as their PoweredArmor.
* Bennie, the robot pilot from ''Webcomic/{{Freefall}}'', carries his brain[=/=]CPU around in a suitcase so he can plug it in to whichever plane he's flying.
--> '''Bennie''': [[http://freefall.purrsia.com/ff2000/fv01990.htm Ever done something and wonder "Where was my brain when I did that?"]]

* In the Literature/WhateleyUniverse, more than one deviser goes with the datajack. Techno-Devil has a shaved mullet, with an exposed datajack on each side of his head. Jericho has one as well. Merry doesn't even need that much (she just has to be near a fast CPU hooked up to the internet, and her mind can literally dive into cyberspace). Since that is in fact her mutant power it may be debatable if it fully counts for this trope, but it's the closest thing to the 'cyberspace experience' depicted in the various stories so far.
* In ''WebOriginal/OrionsArm'', most bionts have Direct Neural Interfaces or [=DNIs=].
* In ''Literature/{{Twig}}'', Jamie, a boy with PhotographicMemory, is regularly plugged into a set of large [[BrainInAJar brains]] using a series of slots in his modified spinal colum. The brains help him organize and process all the data he collects for later use.

* In ''WesternAnimation/ExoSquad'', the [[MiniMecha E-frame]] steering is twofold: the ground movement (walking) is synchronized with the pilot's leg movements, but aiming and flying are controlled via "cyberjacks" connecting directly to the pilot's brain via a socket at the back of his/her neck.
* In ''WesternAnimation/MegasXLR'', Coop meets a future version of himself, and their future Kiva is hooked up to a machine through her brain.
* In ''WesternAnimation/RegularShow'', after Techmo fails to take down a virus with a super-hi-tech keyboard complete with DOUBLE holo-Pads, he plugs himself into the computer in this manner. It doesn't quite go according to plan, though.

* A number of different [[http://en.wikipedia.org/wiki/Brain-computer_interface#Commercialization_and_companies Brain-computer interfaces]] have actually been developed for the disabled and gaming. Hasbro's [[Franchise/StarWars Force trainer]] is one of the latter. Most commercial versions are non-invasive and actually read subtle changes in your scalp rather than actual brainwaves.
