| Research Abstract |
It is hoped that the objective criterion of the somatic sensation would be established in clinical situations because lawsuits for nerve injuries have come to pose serious problems. In this study, we have analyzed spatiotemporal brain electrical activity when given the mechanical tactile stimuli using a piezoelectric actuator. Realistic-shaped cortical potential imaging was applied to the somatosensory evoked potential. As a result, the positions and strengths of the stimulation could be distinguished by paying attention to negative peak about 80ms after tactile stimulus.
