Brain regions bearing a significant parametric effect of fear extinction as presented by an exponential decay related to relative increases in AEA (INC groups) versus decreases (DEC groups), at a threshold of p < 0.001 (voxel level) and FWE-corrected (p < 0.05) cluster sizes (corresponding to 169 voxels).
