Figure 3. Averaged equivalent current dipole positions. (A,C) Comparisons of the three-dimensional equivalent current dipole locations on each axis between 3 regions of the hard palate and median nerve stimulations are shown for 1M (A) and 2M (C) components. Somatosensory representation of palatal mucosa in the primary somatosensory cortex shows anterior and inferior orientations in the primary somatosensory cortex, compared with representation of the hand area. (B,D) Distances of equivalent current dipoles from each site on the palate to the median nerve are shown for 1M (B) and 2M (D). Each site for the palatal area in the primary somatosensory cortex was localized contiguously. Statistically significant differences are labeled with asterisks (P < 0.05).
