Neural bypass allows paralysed man to move his hand
Computer reads brain activity and stimulates muscles in the forearm
Chad Bouton, Vice-President of Advanced Engineering and Technology at the Feinstein Institute for Medical Research in Manhasset, New York, led the team.
There were several key elements in the system, including an implant surgically attached directly to the motor cortex of the brain, a computer that then used machine learning to decode neural activity and translate it into a pattern of electric impulses, and a sleeve that attached to the volunteer's forearm, containing more than a hundred electrical connectors that stimulated muscle activity that controlled hand movements. Mr. Bouton stresses that this experimental technology is still many years from widespread use.
