The roles of the PRh and BLA in extinction of sensory preconditioned fear. A, Extinction of sensory preconditioned fear does not require activation of the PRh or NMDAR in the PRh (Experiment 4A: EXT-MUS, n = 8; EXT-IFEN, n = 8; EXT-VEH, n = 8; NO-EXT, n = 7). Left, Freezing to S2 during the test for extinction of sensory preconditioned fear. Right, Freezing to S1 during the test for retention of first-order conditioned fear. B, Extinction of sensory preconditioned fear requires activation of the BLA and NMDAR in the BLA (Experiment 4B: EXT-MUS, n = 8; EXT-IFEN, n = 8; EXT-VEH, n = 9; NO-EXT, n = 9). Left, Freezing to S2 during the test for extinction of sensory preconditioned fear. Right, Freezing to S1 during the test for retention of first-order conditioned fear. Data shown are means ± SEM.
