  • Z scores for the brain stem and thalamus in the comparison of FRS vs. baseline are reported in the parentheses to show a tendency of increased rCBF. x, y, andz, stereotactic coordinates in the three orthogonal dimensions of the atlas by Talairach and Tournoux (1988). GTT, transverse temporal gyrus; GTs, superior temporal gyrus; lt, left; rt, right.
