Brain in a Jar

"We are all aware that the senses can be deceived, the eyes fooled. But how can we be sure our senses are not being deceived at any particular time or even all the time? Might I just be a brain in a tank somewhere, tricked all my life into believing in the events of this world by some insane computer? And does my life gain or lose meaning based on my reaction to such solipsism?"Project PYRRHO, Specimen 46, Vat 7 Subject termination advised

The Wonders of Science can keep a human brain alive in a plastic fishbowl with a few wires and doo-dads running into it. Sometimes this is benevolent, but usually it's nefarious (it may count as a Dark Lord on Life Support, or be the first step towards Unwilling Roboticisation). Occasionally, an underachiever Mad Scientist may need to keep the whole head alive, not just the brain. Sometimes the spinal cord and/or eyeballs are also there.

Sometimes it is presented as the end result of natural evolutionary processes. One day, we may find the rest of our bodies superfluous and exist simply as disembodied brains.

Also frequently falling under this trope is the Poor Man's Substitute of severed heads kept alive in jars or on surfaces that can disguise the fact that the rest of the actor is beneath the table when the head is active, which at least has the advantage of allowing the actor to act in some scenes.

Occasionally with this trope, the brain is hooked up to a virtual reality so that it thinks it's a regular person with a body, making it a sort of Lotus-Eater Machine. See The Other Wiki's article "brain in a vat" for further discussion of this idea.

It seems that in about one in five examples of this trope the brain will be Hitler's. Walt Disney (or more likely a No Celebrities Were Harmed Expy of him) is also popular. Expect them to be given mobility by being encased in robotic life support units... with Death Rays! For Science!

Keep in mind that in real life, just pulling the brain out of a living person's head and plopping it in a tub of sterile saline would leave you with a starved, dead brain the next morning, so you'd need to hook the blood vessels up to some sort of fluid pump (ala the heart) to keep the brain supplied with oxygen and nutrients. But then you'd also need an air pump (ala the lungs) and nutrient intake device (ala the digestive tract) to keep that fluid pump supplied with that oxygen and nutrients. And then you'd need a regular filtration system (ala the urinary system) to keep the brain from dying of "blood" poisoning. But at this point it all amounts to basically a near-complete prosthetic body, so you might as well attach some limbs and call it a robot with a Wetware CPU, or a Full-Conversion Cyborg.

Compare with People Jars and Man in the Machine; pretty much the same thing, but with complete bodies instead of just a brain. Compare also Soul Jar, in which the more immaterial essence of one's self is preserved. Compare Heart Drive, for a robotic (and sometimes biological) equivalent. Compare with Oracular Head when the head may be preserved by other means and used for answering questions of a divinatory nature. Wetware CPU is a version used as a computer.

Compare to Losing Your Head when the whole head is preserved and capable of independent movement. Compare Brain Transplant when the brain is given a new body. This may or may not lead to And I Must Scream. May also be a result of Brain Theft. See also Brain Monster for brains that don't need to be preserved to survive. Subtrope of Jar of the Bizarre.

    • Gremmy Thoumeaux is revealed to be a brain in a jar held in an artificial body made by his Imagination-Based Superpower.
  • Buso Renkin: After being paralysed from the neck down, Alexandria, Victor's wife, transferred her brain life preserving jar to preserve her life long enough to develop a way to make him human again. Over the years Alexandria also repeatedly cloned her brain so that she could link their jars together in an attempt to boost her already genius level intellect.
  • Captain Future: Simon Wright is an archetypal brain in a (highly mobile) jar, with a tractor beam, other appendages, and an array of blinkenlights for a mouth.
  • A Certain Magical Index:
    • Teitoku Kakine has been reduced to this after Accelerator horribly dismembers him. It's also forced to create a constant stream of Dark Matter for the use of Academy City's soldiers. He eventually manages to create a new body out of Dark Matter and escape.
    • Rensa is a cyborg with forty different brains that can be inserted into her head to animate her. After Touma destroys Rensa, he finds the brains and puts them into cold storage until something can be done about them.
    • In A Certain Scientific Railgun, Exterior is revealed to be a giant brain in a tube, cultivated from part of Misaki's cerebral cortex. It was intended to allow other people to use the ability Mental Out.
  • Cyborg 009: In the 2001 version, the true leaders of Black Ghost are three brains in jars, hiding inside a shuttle. The three can somehow speak: one talks with a man's voice, another with a woman's, and the third has a child's one.
  • Dragon Ball Z:
    • Dragon Ball Z: The World's Strongest, the second movie, features Dr. Wheelo, who seems to be a brain in a jar. But then turns out to be a brain in a jar in a massive mecha. With guns. And lasers.
    • In the main series, as an android, Dr. Gero's brain is stored in a glass dome on his head. It's usually covered by his nice hat, though.
  • EX-ARM: In the beginning, Akira has been reduced to a brain in a titanium suitcase but can control hacked electronics, including an Animated Armor, like he would his own body.
  • Final Fantasy V: The anime sequel has the Big Bad steal Cid's corpse from his tomb and resurrect him as a HUGE brain. Seriously, it's several times the size of a human.
  • Ghost in the Shell:
    • Most full cyborg models allow for the case that holds the brain to be removed and connected to an external life support system. In one episode of Ghost in the Shell: Stand Alone Complex, a government official is about to be smuggled out of the country by hiding his brain in a suitcase. In another, an unconventional movie director decided to eschew his body, placing his brain case into a networked life support system and waiting for any wandering divers to come watch the movie in his brain.
    • Both the anime and manga versions have minor characters described as Jameson-type cyborgs (it's a brand name) which take this more literally than most. Most full-body cyborgs have a body that at least looks human but Jameson-types eschew this with a roughly cubic metal box on wheeled legs with a camera on a stick and a manipulator arm. For extra irony, in the anime, one runs a company that specializes in growing cloned organs for those who don't want cybernetic replacements if injured... and he got the money to found the company by selling all his organs in the first place (he was noted as being something of a "gung-ho company guy" considering the lengths he was willing to go to make a sale).
    • The central character, Major Motoko Kusanagi, is a full cyborg and thus this trope. The purple-haired bombshell is the jar.
  • Kamen Rider: In Shotaro Ishinomori's original manga version, Takeshi Hongo, the Kamen Rider himself, is mortally wounded fighting the Shocker Riders. His brain is hooked into a computer and he becomes Mission Control for Hayato Ichimonji, who takes up the Kamen Rider mantle. In the final chapter, Hongo's brain is implanted into a fully mechanical body and he helps Ichimonji defeat Shocker once and for all.
  • Knights of Sidonia: The traitorous Ochiai had his cybernetically-enhanced brain taken out and placed in storage after he destroyed most of Sidonia's libraries and data stores, leaving him the sole possessor of the knowledge they possessed. A clone of him, conditioned to be loyal to Sidonia, was created to act as a medium through which they can access his knowledge. Ochiai's mind eventually escapes confinement when he takes over Norio Kunato's body.
  • Lupin III: In The Mystery of Mamo, at the end, it turns out the movie's main villain was a gigantic version of this trope all along, and all the "clones" of him running around were all controlled with microchips in their brains that were wirelessly connected to him.
  • Mazinger Z and Great Mazinger: The Kedora. Ken Ishikawa one-shot "The Relic of Evil" revealed that the Mykene controlled his Robeast by grafting the brain of a soldier taught to destroy all non-Mykene civilizations into a parasitic organism, and it fused with a robot, giving the Mykene soldier complete control. They would show up later in Shin Mazinger.
  • Neon Genesis Evangelion: The Magi computers are powered by human brains. However, although an episode mentions "organic supercomputers" that bear a strong resemblance to a human brain, it's not clear whether they use actual cloned human brain tissue or are just reverse-engineered. The best that can be determined is that all three are based on the brain of Dr. Naoko Akagi (Ritsuko's mother) or rather specific aspects of her: one is based on her as a scientist, one on her as a mother, and the last on her as a woman.

    Card Games 
  • Gloom: Lord Slogar is a brain in a jar. Presumably his condition is the result of an experiment by his Mad Scientist wife, Helena.
  • Magic: The Gathering:
    • A longtime Running Gag on the website is that Magic's Research And Development department is run by Gleemax, a literal brain in a jar, which even has its own (not tournament-legal) card. The gag dates back to at least the February 1998 issue of the long-defunct Duelist magazine, in which Mark Rosewater explains the 'Top Ten Myths About Magic R&D' — the myth about Gleemax is listed as #1, and it's not quite clear from context whether MaRo refers to an actual earlier myth or is just throwing in a red herring on the fly.
    • The Psychosis Crawler is a brain in a tank of fluid mounted on a Spider Tank. The abundant space in the vat and the card's flavor text imply that more than one brain might find its way into that jar.
      "If that brain can't figure out the secret of the serum, then add more brains."
      —Rhmir, Hand of the Augur
    • No longer content to merely beat around the bush, Shadows over Innistrad goes for broke and includes a card directly named "Brain in a Jar".
    • Innistrad: Midnight Hunt includes the Larder Zombie, depicted in the act of trying to gnaw through a glass jar to get to the preserved brain inside.
  • Munchkin: The Brain in a Jar is an enemy in Star Munchkin.
  • Yu-Gi-Oh! has Mind Master. There's also the brain in the Field Spell Brain Research Lab, which might actually be the same one as Mind Master.

In Captain America Corps, the altered timeline has him reduced to a brain and eyeballs in a glass cylinder by Superia, his intellect used to devise her weapons, with him begging for death. During a Dark Avengers arc that deals with a pocket timeline controlled by A.I.M., the Tony of said timeline has long since been reduced to a brain in a flying sphere. He apparently keeps this secret from all his allies, who just assume he never takes off his armor anymore.
    • In Avengers: The Initiative, Think Tank is a member of Montana's state superteam, Freedom Force.

All of these persons being non-humans of various species, some with a Bizarre Alien Biology like an alien with an X-shaped head and four small brains require quite specific jars.
  • In Sonic the Hedgehog (Archie Comics), after Dimitri is stripped of his Enerjak powers, he's put on heavy life support. Later, after being experimented on by Doctor Finitevus, his head is removed and placed in a floating bubble.

    • In which Twilight Sparkle turns herself into a brain in a jar for perfectly logical reasons.
    • Brainy Twilight once crossed over with Serious Rainbow to see if putting Serious's brain in a jar would override her Resurrective Immortality. The answer was no; it produces two Serious Rainbows, one's just a brain in a jar. She later takes the nickname Brainbow Dash and helps Derpy out in the lab. For the most part, Brainbow is happy with her life as a Brain in a Jar (except when she found out she could have had C-cups).
  • The true nature of Future Calvin in Calvin & Hobbes: The Series.

  • In Out of the Corner of the Eye, Ephraim Waite has been rendered as one of these, attached to a spider-like mech body, by the Mi-Go. He's perfectly content with this.
  • Sonic X: Dark Chaos:

In this version, the brain is ultimately destroyed in a house fire.
  • Fiend Without a Face: The titular "fiends" are initially invisible monsters that, when revealed, are actually slimy crawling human brains that brains strangle victims with their spinal cords. While not in jars during the events of the film, one of the "fiend" puppets was displayed in a jar at a movie theater during the film's premiere.
  • In Frankenstein Island, a human brain in a glass dome is essential part of Sheila and Van Helsing's aparatus.

  • The Whisperer in Darkness (2011), in which the alien Mi-Go plant living human brains in cylinders to transport them to other planets, which the human body apparently cannot withstand. The film ends with The Reveal that this happened to Albert Wilmarth himself, and the entire story he's been relating is a holographic projection coming from a brain in a can.
  • Young Frankenstein:
    • Igor is sent to retrieve the brilliant Hans Delbruck's brain from the Brain Depository, where brains in preservative-filled jars are lined neatly on the shelves. Igor drops the jar containing the scientist's brain, and instead takes a different jar marked "ABNORMAL — DO NOT USE". After the monster reveals its true nature, Dr. Frankenstein asks Igor whose brain he put in the body. "Abby someone." "Abby who?" "Abby Normal."
    • In the German-dubbed version, this becomes "I took the brain of a cleric, an abbot (Abt)." — "What abbot?" — "Abt Normal." By the way, as he mentions on the DVD, Mel Brooks had Frederick Frankenstein send Igor to fetch Hans Delbruck's brain because that would rhyme with "Mel Brooks' brain". So it is not a reference to the German politician and historian Hans Delbrück (1848-1929), father of the Nobel Prize-winning German-American biophysicist Max Delbrück (1906-1981).

  • One bad ending in the Star Challenge books has this happening to you. Your brain is inserted in an armor by an alien who says that he collects heroes' brains, as they're far easier to maintain.

The true identity of the Toclafane is a major plot point (and point of horror): they're the last remnants of humanity from hundreds of trillions of years into the future, who turned themselves into a race of hive-minded, child-like sociopaths in order to survive the heat death of the universe. Why would they slaughter their own ancestors? Because it's FUN!

  • The Big Bad of the BBC series Earthsearch are AN.G.E.L. (Ancillary Guardians of Environment and Life) One and Two, the organic Master Computers of the Challenger, who look like this trope in appearance (at least in the novelisations — in the radio series they're described as two racks of integrated wetware). Unfortunately, such organic computers have a tendency towards megalomania.

  • Call of Cthulhu: This is the usual fate of anybody who gets on the wrong side of Mi-Go. That's not to say that they did it to you because you pissed them off; that just gets them to kill you. No, they slice out your brain and put it in a jar if they like you. The resulting brain cylinder can survive in Yuggoth's hostile atmosphere and be plugged into external devices allowing it to "see", "hear", and speak, but being sapient fungus monsters with a radically different physiology from humans, Mi-Go don't have the best grasp of human senses.

These are created from the brains of a few illithids, the first to die in a colony, and others are added to the pool later as members die, as a sort of immortality. They can also do this to mortal brains with particularily interesting thoughts (that aren't eaten). This whole trope is basically their hat.
    • Various undead supplements have provided more normal-sized brains in jars, like here for example.
    • Ravenloft has a brain in a jar, salvaged alive from an accident victim by Dr. Frankenstein Expy, which is a mind-controlling criminal mastermind in Dementlieu.
    • Forgotten Realms: The mind flayers of Oryndoll store many brains of those they think knew too much, alive and available for telepathic probing as a "library". Presumably, their own divine Elder Brain could absorb all this, but then it would be pestered with unimportant questions.
    • Dungeon magazine #44 adventure "Raiders of the Chanth": The Chanth is a giant brain that is the magical combination of the brains of a man, a dwarf, an elf, a halfling, and a thri-kreen. It exists inside a sphere of glass under the effect of a Glassteel spell. It is extremely dangerous due to its extensive psionic powers.
  • Eclipse Phase: Transhuman introduces the Brain Box enhancement, an organic human brain in a box that contains a small life-support system, and which is usually mounted in a robot body. It's favored by characters who like the durability of a synthmorph, but are paranoid about brainhacking or want to use Psychic Powers.
  • Gamma World: Borgs, Permanent Cybernetic Installations and Think Tanks in 1st Edition. Borgs in 2nd Edition.
  • GURPS:
    • The game has a disadvantage called "No Physical Body" which turns you into this. You're immobile, and anybody who interacts with you is likely to recoil in horror. So it kinda sucks, except that it gives you a ton of character points that you can spend on magic/psionic powers or other mental abilities.
    • One of the vignettes in GURPS Magic Items 3 is about a brain trying to hire Humphrey Bogart to find his body.
  • Mutants & Masterminds: First edition, using the META-4 universe, has the Atomic Brain who was a former Manhattan Project researcher whose brain survived the explosion of an experiment. A combination of resentment at Oppenheimer taking credit for the atomic bomb and frustration over a lack of limbs led to the Atomic Brain becoming a supervillain. However, Atomic Brain's... brain... floats above his robotic body.
  • Pathfinder:
    • The adventure module Wake of the Watchers features a "brain archive" containing several of these.
    • Part of the Reign of Winter Adventure Path takes place on Earth circa 1918, where the party will encounter Mk. V tanks driven by implanted human brains.

  • Shadow of the Demon Lord: The psionics focussed Brain In A Jar Master Path allows player characters to become one by level 7.
  • Shadowrun
    • Supplement Threats 2, section "Halberstam's Babies". The evil scientist Dr. Halberstam continues his experiments by extracting the brains of children and storing them in containers, then connecting them to the Matrix and training them to be super deckers.
    • Supplement Aztlan:
      • Thomas Roxborough, a major shareholder in Aztecnology, is currently a mass of undifferentiated protoplasm (including his brain). Sort of a "cancer in a jar".
      • Aztechnology is rumored to be working on biocomputers - computers based on human brains floating in a vat of electrolytes.
  • Star Frontiers module SF1 Volturnus, Planet of Mystery. The slavebots in the Sathar Artifact are controlled by a Sathar's brain which is in a large fluid-filled flask. The flask is connected to a radio with wires.

    Web Animation 
  • Lobo (Webseries): One of the prisoners at Oblivion is a brain with spikes in a jar labeled "criminal mind".

  • The super-villain Dr. Haynus from Greystone Inn and its sequel comic Evil, Inc. is a disembodied brain in a jar. As he is on top of a living puppy with a mind of his own, Haynus unfortunately feels the humiliation of not having control over its actions: Anyone can get rid of Haynus by simply using a ball or cookies.
  • Girl Genius: Anevka Sturmvoraus is basically one of these, although her container is much larger than a typical jar, and is attached via cables to a robot "clank" through which she can interact with the world. And it is eventually revealed that the brain died long ago and the robot is unknowingly operating itself via the deceased's imprinted personality. Later, the "whole head in a jar" variant is done to a particularly high-ranking Mook so that he can be kept safely alive and in custody while being pumped for information, and references have been made to doing the same to other characters (or inability to do so, owing to the lack of a head). In general, it seems to be a well-known, if maybe not exactly common, practice.
  • In Homestuck, Dave comes across the alchemy combination that makes Dave's Brain In A Jar during his experiments with Item Crafting. It's too expensive for him to make because the organ is virtually inimitable, but he uses the code in alchemy to make the SBAHJifier camera.
  • Adolf Hitler is a brain in a jar in the LEGO photocomic Irregular Webcomic!. At one point he builds a supercomputer out of a bunch of cloned Hitler jar-brains wired together.
  • The entire Baro race from Marooned is brains in jars, uploaded into the Mother Brain upon death.
  • In Minion Comics, Hitler's head is seen in a jar attached to a giant rampaging gorilla.
  • In Narbonic, the Bad Future version of Helen Narbon is one of these and resentful as heck about it. In the finale, as the events that caused this almost come to pass, we learn the reasons for both brain-in-a-jarness and bitterness.
  • In this The Order of the Stick strip, Xykon references Brain in a Jar transformations as a method to avoid death. Though he makes it clear that he wouldn't become one unless he had to.
  • Schlock Mercenary:
    • Just about all of the original Toughs (except Schlock) end up as heads in jars after the 2001 Schlocktoberfest storyline. This gives the frequently disembodied Der Trihs a sense of deja vu.
    • Anyone injured badly enough would end up with their head in a jar and with a few punchlines at their expense (usually by Ennesby, embittered over not having a body in the first place) was a running theme, especially earlier in the comic's run. Full-body regeneration has also been used since as a plot device, as once you get started there's really no need to regenerate a body EXACTLY like your old one. If your vanity or your job demands require a physical upgrade, well, here's your chance! More muscle (Nick), more height (Elf), less fat (Thurl and Xinchub), you can have a whole new you from the shoulders down. Why don't people do it all the time, then? It's expensive.
  • Nick Zerhakker in the spin-off Skin Horse is one of these as well, installed in a V-22 Osprey. As of "The Iron Man" Nick has lost the helicopter but gained a clone of his human body, though he'd come to see his helicopter chassis as his "real body" by then.
  • Serix: Mentioned as the state a large portion of humanity are in. It seems to be voluntary, since they can still use the Mindnet and can transfer their consciousness into robotic or organic bodies whenever they want to interact with the real world.
  • A Brain in a Jar alien makes an appearance in this Sluggy Freelance strip, with the added twist that the creature's brain is divided into a right and left side, each in separate jars.
  • Spacetrawler: They show up in the spacetrawler construction facility.
  • Supertron: Supertron (actually named Simon)'s father is basically a brain in a jar, which also houses his eyes, intestines, and other organs.

  • SCP Foundation
    • Log of Anomalous Items. One entry is a human brain floating in a vat of nutrient solution. The vat can move around and has a speech synthesizer and a camera. The brain claims itself to be Zargox Quaglofan, a 23rd-century secret agent on a time travel mission to prevent the creation of the Insectoid Empire in 1976.
    • SCP-748 ("Industrial Dissolution"). The SCP-748 facility is controlled by the brain of its creator, which is stored in a vat. Nearby are 200 lobotomized human brains contained in glass cylinders filled with a green liquid. They act as auxiliary memory for the controlling brain.

    • SCP-2099 ("Brain in a Jar"). SCP-2099 is the brain of Jeremy Valdez, which floats in a glass jar filled with water, green food coloring, artificial flavoring, sugars, and electrolytes. The Foundation is unsure if that's what's actually keeping Jeremy alive, or if that's what he thought would be aesthetically pleasing. It uses devices (such as a robot and mechanical hands) to manipulate objects.
  • According to Pat R's series of articles on the Final Fantasy series, when an intern suggested the Job System during the development of Final Fantasy III, Hironobu Sakaguchi (the creator of the series) responded by pausing blankly, heaping rewards on him, then chloroforming him and putting his brain in a jar so that Squaresoft would never be without his genius. The article goes on to describe some of the brain's other accomplishments, before its tragic downfall at the hands of the designer of Final Fantasy II.
  • As seen in this ironic Teach the Controversy T-shirt featuring a chipper Walt Disney.
  • Team Four Star revisits the World's Strongest movie from Dragon Ball Z, where it doesn't hurt that having a minimum of visible animation, movement and dialogue, the movie's villain has a serious different character as a confused old scientist who spends most of the production watching Dr. Kochin go about committing horrible, Stupid Evil plans to give him a new body. (He cites the fact that he's "a brain in a jar" to say that he's not the one controlling someone in a fight; Goku just takes this as direct confirmation of villainy — "So you admit it!")
  • In Twig, it's eventually revealed that Jamie's Photographic Memory is actually the result of being an interface for a huge collection of these.
  • Whateley Universe:
    • Not surprisingly, Devisors have done this several times, to themselves or others.
    • While not a Devisor himself, the student Psike, a PDP and one of the senior Bad Seeds in the 2006 stories, was 'rescued' by other students in this manner after an accident destroyed his body. He claims to prefer this, being contemptuous of ordinary 'meat bags', but does decide he needs a human body he can control remotely in order to take care of things his mind control, telekinesis, and sterling personality can't.
  • Dynamo Dream: The Floorhead is literally a head in a jar. He has a setup that allows him to speak using his eyes and an IPA phoneme chart.

    Western Animation 
  • Adventures of the Galaxy Rangers: Tactical Commander Owen Negata, a BETA research scientist and tactician, was killed in the Supertrooper Riot (though we don't learn this until later). What was left of him can fit into a little jar attached to a 1.5 meter by one meter repulsorlift platform. Zozo is rather shocked by it.
    Zozo: That's Commander Negata?!
    Waldo:' His brain unit. His body died years ago.
  • Adventure Time: In "Dark Purple", what appears to be a giant brain is kept in a tank in the pure Super Porp processing room.
  • Buzz Lightyear of Star Command: While the Star Command employs the Little Green Men seen in Toy Story, Zurg's minions are brains in jars (who frequently mention this situation when the boss complains).

    • Mr. Freeze is eventually reduced to this after his condition worsens. He was able to slow it down with the aid of some kidnapped scientists, but by that point, he had already lost everything from the neck down. To make things worse, his condition has also made him The Ageless. By the time of Batman Beyond, he's still alive... as a disembodied head stuck in a glorified meat locker. He's later given a healthy body, but snaps and returns to his villainous ways before dying in one final rampage.

And both are occupying the body of a Russian circus bear named Boskov who can still act on his own despite his brain being replaced with Hector's.
  • The Fairly OddParents!: In "Future Lost", the evil brain that aspired to take over has a strange weakness — put juice pills in its tank, and it gets a Brain Freeze. They also dump some ice into it, making a giant slushie. Also, every Yugopotamian has their brain clearly visible in a glass dome on their heads.
  • Futurama:
    • The show has the heads of various 19th-21st-century personalities preserved in jars, including Richard Nixon, who eventually becomes president again through Exact Wordsnote . Used more for comedy and satire than creepiness. It's never explained exactly how, say, George Washington's head could have been preserved in the first place. Also, the main antagonists of several episodes are flying brains outside of their jars.
    • "How Hermes Requisitioned His Groove Back": A robotic version — Bender's personality and intelligence are downloaded into a floppy disk.
    • Inverted with Earth President Nixon's vice president, Spiro T. Agnew, who is a headless body.
    • This process is eventually Hand Waved as being a form of limited time travel; by incorporating some kind of powdered opal into the fluid that the heads are kept in, they create a tiny bubble in which the heads are perpetually in the time period during which they were alive. Presumably, a certain amount of cloning is involved for certain heads as well.
  • He-Man and the Masters of the Universe: Modulok tries to do this to Man-at-Arms in "Happy Birthday Roboto", though he's actually using the second head that came with his toy in the episode instead of a jar.

    [everyone present groans]
  • Teenage Mutant Ninja Turtles (2003): After starting out as a human, Baxter Stockman's Serial Prostheses eventually leaves his brain as his only organic part.

The journal is then revealed to be a hoax.

  • The Venture Bros.: In the "Morphic Trilogy", it's revealed that Jonas Venture Sr. was ejected into space during the Gargantua-1 disaster, and the other members of Team Venture put him into a life-prolonging machine he built but were only able to preserve his head after they dropped his frozen body. They thought it didn't work until he revealed himself to be alive by trying to communicate through the VenTech Tower's systems.
  • Wacky Races (2017): The Creator in "Wackyland" is the isolated brain of the TV executive who greenlit the original cartoon.

    • The Brain is a founding member of the Light, although he ultimately falls Out of Focus and is no longer with them as of the show's third season after being apprehended by the heroes.
    • Come the fourth season, this trope is revealed to be how the Kaizer-Thrall, a sapient device loaned to Lor-Zod and his crew by Darkseid, was constructed. Miss Martian established a link to him and revealed him to be a pre-teen Danny Chase, a trafficked metahuman whose brain was extracted by Desaad and integrated with Apokoliptian technology.

    Real Life 
  • Animats or Cultured Neuronal Networks are almost a Real Life version of this trope, "almost" because they aren't complete brains (and are usually animal neurons rather than human).
  • Averted by Mary Roach, author of Stiff, a nonfiction book about cadavers. Investigating the possible fates which await deceased human bodies, Roach considered donating her own to Harvard's medical school, in hopes of becoming a brain in a jar. To her disappointment, she learned that human brains preserved there for medical and scientific research are kept in plastic food containers, which hardly seemed worth it.
  • Dr. Albert Einstein requested in his will that his brain be removed for study and the rest of his body cremated. The brain is currently spread across multiple jars and a few dozen microscope slides.
  • According to the Boltzmann brain hypothesis, if one considers the probability of our current situation as self-aware entities embedded in an organized environment, versus the probability of stand-alone self-aware entities existing in a featureless thermodynamic "soup", then the latter should be vastly more probable than the former if both scenarios are to be created out of random fluctuation. As that is something very Mind Screwy, and even more when one considers the possibility of other universes existing, solutions to that paradox include the possibility of the fabric of the Universe being metastable and degrading after a really very long time, so no Boltzmann brains appearing out of nowhere— same for other universes should they exist.
  • Dr. Robert White's experiments with dogs, rats, and monkeys.
  • Conspiracy theorist Francis E Dec believed that our real brains are in "brain bank cities" on the dark side of the moon and our heads contain only a transmitting device connecting us with them. This is all to enable Gangster Computer God to control us, of course.
  • Number six on Cracked's The 8 Creepiest Places on Earth (Part 4), an abandoned underground Soviet facility beneath Moscow filled with brains in jars, which has virtually no information about it nor any indication as to why it was abandoned in the first place.
    • The website English Russia, who took the pictures used in the article, notes that it was a place to study brains and the nervous system. It was shuttered due to Russia's abysmal economic situation after the collapse of the Soviet Union. The only thing rather ominous about it is that the scientists went to some rather extreme lengths to keep everyone out of there, so much so that no one successfully broke in for upwards of fifteen years. They could have just been trying to assure that their research was found by the right people, though.
  • A functioning brain in a jar would be surprisingly difficult to accomplish in real life, at least without major personality changes — to the point of possibly no longer having a recognizably human outlook — since any number of hormonal and even metabolic functions performed in other parts of the body contribute significantly to brain function.
  • According to a government official who appeared on MythBusters when the boys were testing the "second gunman on the grassy knoll" myth, the National Archives have John F. Kennedy's brain in a jar as evidence from the assassination investigation. Or should we say "had", because according to the same official, the brain has gone missing (apparently the family later buried it with JFK's body).
  • Diogo Alves, a Portuguese Serial Killer, is known for both being the last executed person in Portugal, and for his head being taken for study by a professor of medicine. That head is currently on exhibit at the Anatomical Theater of the Faculty of Medicine of the University of Lisbon.
  • The head of Luigi Lucheni - the assassin of Empress Elisabeth of Austria - sat in the morgue of Geneva (where the crime took place and where Lucheni was imprisoned) from his death by hanging in 1910 to 1986, upon which it was taken to the Museum of Pathology and Anatomy in Vienna, with the condition that it was not to be displayed. It's perfectly preserved in formaldehyde. His head was preserved because, allegedly, experts of the time wanted to study the criminal mind. The modern-day Geneva Morgue, however, was more than happy to be rid of it. He was finally buried in 2000 at the Zentralfriedhof (Central Cemetery) in Vienna, after a long bureaucratic process.
  • A rather horrifying example exists in the case of Staten Island teenager Jesse Shipley, who was killed in a fatal car crash in 2005. Sometime after his death, some of his classmates attended a school field trip to a morgue, where they encountered a brain preserved in a jar labeled with his name. What's worse is that it had been removed without the knowledge or permission of his parents, who later pressed charges. Shipley's body was later disinterred and reburied with the brain.
