Sensory modulation of voluntary and TMS-induced activation in hand muscles.

abstract：:Touches on one hand or forearm can affect tactile sensitivity at contralateral locations on the opposite side of the body. These interactions suggest an intimate connection between the two sides of the body. Here, we explore the effect of masking not across the body but through the body by measuring the effect of a ma...
