Statistical peaks showing the regions where binding potential was greater during the control than during the stress condition. A T value of 4.01 corresponds to a p value of 0.05 corrected. The x,y, and z coordinates (in millimeters) refer to the stereotaxic space. The first column lists the true peak coordinates in our experiment, which are in so-called MNI space, because they were obtained as a result of using the MNI template for transforming subject MRIs to stereotaxic space. For comparison with the atlas of Talairach and Tournoux (1988), we computed Talairach coordinates using the following formula: x′ = 0.88x - 0.8; y′ = 0.97y - 3.32; z′ = 0.05y + 0.88z - 0.44.
