Monocular and binocular neuronal activity in human visual cortex revealed by electrical brain activity mapping.

abstract：:Observation of hand movements has been repeatedly demonstrated to increase the excitability of the motor cortical representation of the hand. Little attention, however, has been devoted to its effect on somatosensory processing. Movement execution is well known to decrease somatosensory cortical excitability, a phenom...
