Abstract
In this study, as a part of comprehensive approach to develop an interface for tactile information delivery, we aimed at capturing the relationship between neuronal and perceptual sensitivity characteristics of in human hand as indexed by neuromagnetic and psychometric responses.
Airpuff stimuli were presented to multiple locations on the ventral side of subjects’ palm, which somatosensory evoked responses were observed.
As a result, it was observed that the latency and amplitude of the evoked responses in the primary somatosensory area (SI) was not related to the location on the palm. Although mechanoreceptors in the palm area distributed densely at both the center of the palm and the proximal part of the proximal phalanges, no effects on location were found by the amplitude of the evoked responses at SI area. These results suggested that amplitude of the evoked responses at SI did not depend on the distribution of the mechanoreceptors.
