Grasping a cup or brushing hair or cooking a meal requires feedback that has been lost in amputees and individuals with paralysis -- a sense of touch. Researchers have now used direct stimulation of the human brain surface to provide this basic sensory feedback through artificial electrical signals, enabling a person to control movement while performing a simple task: opening and closing his hand.
