Performance impaired by anisomycin injections after retrieval recovers with time. Freezing is shown during the retrieval session, which was followed immediately, 2, 4, and 6 h later by injections of 50 mg/kg anisomycin (Ani) or saline (Sal). The retrieval trial was either 3 min (a) or 12 min (b). Mice were tested for 12 min at 1 or 21 days after retrieval. Half of the mice received both the 1- and 21-day tests (Retest); the other half received only the 21-day test (Initial Test). Error bars indicate SEM.
