Temporary inactivation of the BNST does not impair fear conditioning. A: Schematic of behavioral protocol. B: Mean ± SE percent freezing to 5 CS tones during fear conditioning in rats receiving saline vehicle (0.5 µL; n=7) or muscimol (4.4 nmol in 0.5 µL; n=6) 15 min before fear conditioning. C: Mean ± SE percent freezing to the training context for 10 min, 24 hours later. D: Mean ± SE percent freezing to 20 CS tones 48 hours after training.
