A sense of movement elicited in paralyzed distal arm by focal magnetic coil stimulation of human motor cortex

Brain Res. 1989 Feb 13;479(2):355-60. doi: 10.1016/0006-8993(89)91640-5.


Two magnetic coils (MCs) of special design (Cadwell Laboratories) were used to elicit movements predominantly of one or a few digits by percutaneous stimulation of human motor cortex. When cortically elicited movements were ischemically blocked, the MC still elicited a discrete sense of digit movement; a sense of movement map was constructed by stimulating at different scalp sites. Our findings support the existence of corollary discharge.
