This study was to examine the effect of video clip observation performed by another person who pronounced some words with hand gesture on the excitability of lip motor cortex. Transcranial magnetic stimulation (TMS) was applied to the appropriate spot of motor cortex for orbicularis oris during weak voluntary contraction. We found the significant increase of excitability of lip motor cortex during observation for another person's pronunciation with both-hands gesture compared to those with vocalization only or with one-hand gesture. Mirror neuron system, consisted of Broca area and the primary motor cortex in human brain, would be one of the background neural mechanisms for the present results. Because the emphasized visual inputs during observation of the both-hands gesture possibly made the pronunciation imagery clear. It is suggested that the speech with hand gesture could be an effective method to communicate with other person.
