Figure 2. Projections of the activation foci on the lateral aspect of the standard human brain during tongue protrusion and rightward and leftward tongue movements (n = 6). Activations of bilateral sensorimotor cortices that were statistically significant (p < 0.05 corrected for multiple comparisons) are shown. Color code denotes T-values. Abbreviations for Figs. 2 and 3: TP, tongue protrusion; TR, rightward tongue movement; TL, leftward tongue movement; Before, before gum-chewing; After1st, the first 10-minute period beginning immediately after gum-chewing; After2nd, the second 10-minute period from 10 min to 20 min after gum-chewing.
