Human responses to mechanical vibrations delivered to the surface of the skin are given for frequencies between 0.4 and 500 Hz. Vibrotactile response characteristics are given for the threshold of detectability, suprathreshold measurements and for a number of subject variables, including gender and age. Also presented will be the linkage between psychophysical results and underlying neural mechanisms that mediate mechanoreception in cutaneous tissue. [Work supported by grants from NIH, NIDCD.]
