Top. FMRI activation map for the tone decision–rest comparison. The data are presented as sequential sagittal sections from left to right, with the stereotaxic coordinate x-axis,L–R given for each section (see Talairach and Tournoux, 1988). The anteroposterior commissural line (y-axis) and vertical AC line (z-axis) are shown in green. Activated voxels are shown superimposed on stereotaxically averaged anatomical brain images. Probability values for these voxels are coded using the color scale at bottom. One centimeter tick marks are provided to help relate the large activation regions to Talairach and Tournoux (1988). Structures showing bilateral activation include the STG and planum temporale, the supramarginal gyrus, premotor cortex and SMA, midanterior cingulate gyrus, anterior insula, anterior putamen, thalamus, midbrain, and posterior cerebellum. Modest right hemisphere lateralization is evidenced by right unilateral activation in the IFG and MTG and by relative rightward asymmetry in most of the other activated regions.
