Lampshaded in the Silver Surfer's origin. One problem that Norrin Radd has with Zenn-La society is that citizens are hooked up to education machines and gain all their knowledge passively.
The aliens in Battlefield Earth have machines that enable humans to learn their language, how to use their technology, and let them find out how to destroy the aliens.
In the long-running German Sci-Fi pulp action series Perry Rhodan (started in 1961), Terran humans adopted alien technology, the hypno schooling devices, that allow scientific knowledge, language skills and even memories to be transfered and implanted in the brain in just a few hours. The technology is widely used by a number of species in the Milky Way, and it partially psionic in nature. The brain has to be "evolved" enough to accept the imprint, though, otherwise the recipient might go insane. Using a device programmed fpr a certain species on a member of a different species without adapting it first can also lead to unpleasant side effects. Upgrading someone's IQ with these devices is possible, also that often leads to, you guessed it, insanity or brain damage.
Gunn, in the last season of Angel, got a brain implant that instantly gave him an extensive legal education, as well as a bunch of other knowledge (like Gilbert And Sullivan "for the articulation").
Jack O'Neill has had the entire knowledge base of the Ancients uploaded into his head, twice!
I left in the Skylark In Space example, because while it's a knowledge machine and not an intelligence machine, it does give a character access to knowledge (of telepathy) that he couldn't possibly have had before or gained directly from the machine.
Cleaning up the page to remove the examples of Neural Implanting that explicitly aren't this trope. Removed:
Comic Books
Film
Literature
Live-Action TV
