Effects of PR lesions on conditional freezing to the training context. (A) Mean percent freezing to the training context in all three cue groups. Freezing was significantly depressed in the lesioned group (filled bars) relative to the sham-operated control group (open bars). Group differences in mean freezing levels are indicated by an asterisk. (B) Time course of freezing to the conditioning context among animals that were conditioned to the continuous tone. There were significant differences between the lesioned animals (filled squares) and control animals (open squares) in three of the four 2-min time periods. (C) Time course of freezing to the conditioning context among animals that were conditioned to the discontinuous tone. There were significant differences between the lesioned animals (filled squares) and control animals (open squares) in all four time periods. (D) Time course of freezing to the conditioning context among animals that were conditioning to the USV. There were significant differences between the lesioned animals (filled squares) and control animals (open squares) in all four time periods. Error bars represent ± 1 SE.
