A Brown University press release describes what may be a major advance in neuroprosthetics. Researchers have created a direct, real-time, brain interface that allows the user (in this case a Rhesus monkey) to control the movement of a cursor on a computer screen. A tiny brain implant similar to one used in treating human Parkinson's patients monitors a very small number of neurons (as few as six). Mijail D. Serruya, a graduate student, has authored a paper on the work that appears in the current issue of Nature.
