Propranolol (10 mg/kg) experiments. a, b Experiment 1, n = 8 per group. c, d Experiment 2, n = 8 per group. e, f Experiment 3, n = 6 saline rats and n = 8 propranolol rats. g, h Experiment 4, n = 7 saline rats and n = 5 propranolol rats. Percentage freezing during each tone (mean and SEM) is shown. “Pre” is contextual freezing before the first tone presentation of the session. i Acute effects of propranolol in experiment 4, in which the drug was administered immediately before rather than after reactivation, n = 8 per group. Individual data and group means are shown. Light gray box indicates that a session takes place in context A, dark gray is context B. CS, conditioned stimulus; US, unconditioned stimulus; d, day(s)
