Stanford team's brain-controlled prosthesis nearly as good as one-finger

Years of work have yielded a technique that continuously corrects brain
readings to give people with spinal cord injuries a more precise way to tap
out commands by using a thought-controlled cursor. A pilot clinical trial for
human use is underway.

An interdisciplinary team led by Stanford electrical engineer Krishna Shenoy
tested a brain-controlled cursor meant to operate a virtual keyboard. The
system is intended for people with paralysis and amyotrophic lateral
sclerosis (ALS), also called Lou Gehrig's disease. ALS degrades one's ability
to move. The thought-controlled keypad would allow a person with paralysis or
ALS to run an electronic wheelchair and use a computer or tablet.
