Figure 1 - Voxelwise analysis of BOLD responses.

Responses are shown for a group of 14 subjects to (a) voluntary saliva swallow, (b) tongue elevation, and (c) voluntary finger-thumb opposition. Regions of significant activation are displayed on sagittal (left), coronal (middle), and axial (right) brain slices. Talairach-Tournoux plane coordinates are displayed above each image.
