monkey do, humans too

Other researchers have worked with implanted electrodes in both monkeys and humans, but Leuthardt said this approach does not require putting anything deep into the brain.
"There is the potential for it to be very much less invasive," he said.
Writing in Monday's issue of the Journal of Neural Engineering, Leuthardt and Daniel Moran, an assistant professor of biomedical engineering at Washington University in St. Louis, said the patients learned in minutes how to control a computer cursor.
"It took six minutes of training and they all achieved control in less than 24 minutes," Leuthardt said.
"After a brief training session, the patients could play the game by using signals that come off the surface of the brain," added Moran. "They achieved between 74 and 100 percent accuracy, with one patient hitting 33 out of 33 targets correctly in a row."
[...] Leuthardt and Moran centered about 32 electrodes over the sensory motor cortex of the brain and a region called Broca's area, which is associated with speech.
