Effect of DCS in nonextinguished rats.A, Timeline of the behavioral procedures for experiment 3. B, Percent fear-potentiated startle measured 24 hr before and 24 hr after extinction training. Saline or DCS (15 mg/kg, i.p.) was administered 30 min before a single session of either extinction training (cue exposure) or context-alone exposure. Fear-potentiated startle was significantly lower in rats that received DCS plus extinction training compared with rats that received saline plus extinction training. Fear-potentiated startle was not appreciably affected by DCS in rats that did not receive extinction training. *p < 0.05 versus saline plus extinction training.
