Neuroscience: Brain control of a helping hand
John F. Kalaska1
Abstract
Paralysed patients would benefit if their thoughts could become everyday actions. The demonstration that monkeys can use brain activity for precise control of an arm-like robot is a step towards that end.
Strokes, spinal-cord injuries and degenerative neuromuscular disease all cause damage that can severely compromise the ability of patients to use their muscles. The loss of mobility and independence that results from such motor deficits takes a devastating toll on their quality of life.
- John F. Kalaska is in the Département de Physiologie, Groupe de Recherche sur le Système Nerveux Central, Université de Montréal, Montréal, Québec H3C 3J7, Canada.
