Method of analysis used in this study. (A) The MEG waveforms viewed from the top of the head following stimulation of the left median nerve recorded from 204 sensors in the Stationary task. Clear deflections were obtained in the central region contralateral to the side stimulated and in the temporal regions in both hemispheres. (B) The RSS waveforms from 102 sensors in the stationary task. (C) Enlarged MEG and RSS waveforms of the primary somatosensory area (SI), the secondary somatosensory cortex contralateral (SIIc) and ipsilateral to the side stimulated (SIIi), and the parietal cortex (PC). A vertical line indicates the onset of stimulus.
