✦ Synopsis
-
The influence of various intensities and frequencies of vibratory stimuli applied to the human skin on the amplitude of the cortical slow evoked potentials was studied by means of an averaging computer CAT 1024.
-
The intensity-functions revealed experimentally follow the power-function of PLAT~AV and ST~v~s, which holds, too, for the intensity-function of sensation (intensity of stimulus versus intensity of sensation), found in a merely subjective, psychophysical way.
-
The exponents of these power-functions found subjectively are quantitatively well comparable to those found objectively by our method. Thus the subjective sensations can be correlated to objective findings and vice versa.
-
With certain restrictions the findings can also be applied to the results of threshold-measurements following vibratory stimulation of human skin.
