Insider | Linking Your Brain to a Computer Will Soon Be Real

By Adam Rogers 

For years — decades, even — news accounts and scientific journals have featured videos of human beings controlling computers with their minds. A person, often with some kind of paralysis, from either injury or disease, gets a computer chip embedded in their head — tiny, needle-like electrodes plunged into the gloppy folds and wrinkles of the brain. Those electrodes sense the activity in nearby nerve cells — communication among the tens of billions of neurons in the brain, all networked together. Given enough time and the right software, a computer can learn to equate specific patterns of neuroelectric zaps in the person’s brain with a designated action, and then perform the requested function: move a robot arm, point a computer cursor, say the word “yes.”
