| Research Abstract |
The vibrotactile stimulation(89 Hz, 1.9microm) on the facial skin produced the most effective salivation. Furthermore, Oxyhemograbin and Deoxyhemograbin concentrations of fNIRS on the frontal cortex showed the almost zero level, and the effect was the same tendency when we listened to Mozart. The result suggested parasympathetic nerve activity.
