Coordinates, in standard stereotactic space of Talairach and Tournoux (Talairach and Tournoux, 1988), refer to maxima of the z value within each focus of activation. L, Left; R, right. Approximate Brodmann numbers (BA) associated with anatomical regions are given.
Group analysis: threshold set at p < 0.001, uncorrected, and p < 0.05, corrected for spatial extent.
