Top, Schematic representation of injection cannula tip placements for all rats included in experiment 2a. The values to the right of each coronal section indicate the position of each section relative to bregma. Coronal brain images are adapted from the atlas of Paxinos and Watson (1997). Bottom, Muscimol infused intracerebroventricularly or into the parietal cortex 1 hr before context pre-exposure did not affect freezing resulting from immediate shock (experiment 2). Error bars indicate mean ± SEM percentage of freezing during the context fear test.
