Corticospinal Excitability in the Hand Muscles is Decreased During Eye Moveme…

Corticospinal excitability in the hand muscles decreases during smooth pursuit eye movement. The present study tested a hypothesis that the decrease in corticospinal excitability in the hand muscles at rest during eye movement is not caused by visual feedback but caused by motor commands to the eye muscles. Healthy men (M age¼28.4 yr., SD¼5.2) moved their eyes to the right with visual occlusi…
