Abstract
In this paper, we show a tactile sensitivity threshold to a high frequency Amplitude-Modulated (AM) vibration which depends on its carrier frequency. In a previous study, Lamore et al. showed the similar threshold curve which insisted that the Pacinian corpuscle was responsible for the perception. However, our results insist that the Meissner's corpuscle can be responsible for perceptual characteristic of the high-frequency AM vibration. We show our psychophysical experimental results and discuss a characteristic model.
