Figure 2. Inactivation of OFC blocked the retrieval of choice behavior guided by learned taste aversion, but left other taste-guided behaviors intact. A, Top left, Schematic representation of the four-bottle CTA retrieval task (choice CTA). Lower: Infusion of muscimol and baclofen into OFC before test 2 blocked the retrieval of choice CTA (M&B, n = 9; SAL, n = 7). B, Top left, Schematic representation of one bottle CTA retrieval task (no-choice CTA). Bottom, Infusion of muscimol and baclofen into OFC before test 2 did not affect retrieval of no-choice CTA (M&B, n = 9; SAL, n = 8). C, Top left, Schematic representation of the four-bottle CTA retrieval task (choice CTA). Bottom, Infusion of muscimol and baclofen into OFC before taste learning did not affect acquisition or retrieval of choice CTA (M&B, n = 6; SAL, n = 6). D, Top left, Schematic representation of the four-bottle CTA retrieval task that does not involve options to choose from (complex no-choice CTA). Bottom, Infusion of muscimol and baclofen into OFC before test 2 did not affect the retrieval of complex no-choice CTA (M&B, n = 7; SAL, n = 5). E, Top left, Schematic representation of the four-bottle nonlearned taste preference task (no-choice CTA). Bottom, Infusion of muscimol and baclofen into OFC before test 2 did not affect innate choice behavior (M&B, n = 8; SAL, n = 8). Atlas figures indicate placements of injectors' tips in OFC. Solid arrows indicate time of infusion. Dotted arrows indicate injection of LiCl. In this and subsequent figures, color code is the following: blue represents tasks that involve choice (?) and orange represents tasks that do not involve choice (!). Error bars indicate SEM. Sac, Saccharin solution; Quin, quinine. ***p < 0.001.
