Imagine being able to surf the Web, play video games, move prosthetic limbs or control a wheelchair using only your thoughts. The process is called brain-computer interface technology. And while it sounds like science fiction, labs across the globe are developing neural implants that allow users to do all these things.
It's related to neuroprosthetics, in which scientists are able to repair damaged human functions. Artificial retinas can restore eyesight, cochlear implants bring back hearing, and nano-fiber bristles serve as electrodes for stimulating or receiving neural signals for movement.
But what about uploading data into our brains? Gary Stix wrote the article "Jacking Into The Brain" for Scientific American, where he serves as senior editor. He joins Word of Mouth with more.
