Effects of pretraining intra-amygdala infusions of KN-62 on STM and LTM. A, Top, Outline of general behavioral procedures for pretraining intra-amygdala infusions of KN-62 for STM testing followed by LTM testing. Bottom, Mean ± SE percentage freezing for tone and contextual STM and LTM in rats given bilateral intra-amygdala infusions of vehicle (n = 11), 34 ng of KN-62 (n = 9), or 340 ng of KN-62 (n = 12) before training. B, Cannula tip placements from rats infused with vehicle (black squares), 34 ng of KN-62 (gray circles), or 340 ng of KN-62 (white circles) before training.
