A, Brain regions with significant differential response during conditioning versus transfer test, for the conditioned inhibitor (AX– > DX–) and standard safety signal (BC– > DC–). Whole-brain FDR-corrected (p < 0.05) results are displayed on a high-resolution anatomic template in MNI space. B, Partial overlap between the differential response to the conditioned inhibitor at training versus test (AX– > DX–, yellow) and the response to the conditioned threat alone (A+, purple) with activation of the left premotor cortex.
