Effects of DH lesions on AAA/ABA renewal. (A) Mean (±SEM) percentage of freezing exhibited on the conditioning day, with 3 min prior to tone CS onset (baseline) and 1 min post-CS for five trials. All rats were fear conditioned in context A. (B) Extinction to the tone CS. Mean (±SEM) percentage of freezing for the first four CS presentations across the 3 d of extinction in contexts A and B. (C) Mean (±SEM) percentage of freezing for the first 4 min after CS onset during test. Rats were tested for fear of CS in the conditioning context, either in the extinction context (SAME; AAA; open bars) or outside of the extinction context (DIFF; ABA; filled bars). Electrolytic DH (DH-Pre) or sham (SH) lesions were made before conditioning.
