Figure 3. Average and standard error of the mean of the peak latency (A), dipole moment (B), and dipole position (C) of the somatosensory-evoked fields (SEFs) for the stimuli to the tongue, the gingiva, and the lip/cheek mucosa. The left column shows organ-based overall average and standard error of the mean for the stimuli of the upper/lower and anterior (ant.)/posterior (post.) areas of each organ (N = 48). The right column shows comparisons within each organ (N = 12). Dipole positions are shown as relative angles to the N20m dipole for median nerve SEFs. Statistically significant (P < 0.01) differences are labeled with asterisks, whereas non-significance is not specified.
