Figure 2. — Bilateral ilPFC lesions block specific PIT. (A) Both Sham (n = 9) and Lesion (n = 9) animals learned to enter the magazine more often during CS presentation and (B) increased lever pressing for sucrose reinforcers. (C) In Sham animals, responding increased during presentation of the Same CS versus Pre-CS and Different CS, while Bilat animals responded similarly across all conditions. (D) PIT scores (calculated as the ratio of responding during each CS versus Pre-CS intervals) were significantly higher for the Same versus Different CS in Sham but not Bilateral animals. Dashed line at 1 indicates no difference in responding. ((*) P < 0.05. Error bars represent SEM.)
