Table 2.

Significant activations (+ sign) and deactivations (− sign) during the different phases of the experiment in a priori areas of interest (threshold for peak voxel P < 0.001, one‐tailed, uncorrected, Z = 3.09) and in other brain areas (threshold for peak voxel P < 0.0001, one‐tailed, uncorrected, Z = 3.72); number of voxels in clusters computed for threshold of P= 0.001. Contrast: PTSD +/− TENC, context versus baseline.
