Amygdala and vmPFC BOLD signal during threat acquisition and extinction. (A) Left Amygdala activation. (B) Amygdala mean% BOLD signal changes to CS− and CS+ during acquisition, extinction day 1, extinction day 2. (C) vmPFC activation. (D) vmPFC mean% BOLD signal changes to CS− and CS+ during acquisition, extinction day 1 and extinction day 2. Asterisks represent significantly greater BOLD responses to the CS+ than the CS− for each phase, P < 0.01.
