Abstract: | The effects of music with specific intensity on the latencies of the left or right hand motor responses to visual stimuli have been studied. When the latency of the initial motor response is more than 400 ms, the music accompaniment decreases the latency of the motor response of the left hand. It is supposed that the decrease in the mean latency of the left hand response in subjects who are not professional musicians is related to the activation effect of music on the right hemisphere. Music has no effect when the initial motor responses have shorter latencies. |
