Fig. 2. — Effects of intra-amygdala infusions of ifenprodil on LTM. A, Top, Outline of general behavioral procedures for pretraining intra-amygdala infusions of ifenprodil for LTM testing only. Bottom, Mean (±SE) percentage freezing for tone and contextual LTM in rats given bilateral intra-amygdala infusions of vehicle (n = 10), 0.1 μg of ifenprodil (n = 6), or 1.0 μg of ifenprodil (n = 8) before training.B, Top, Outline of general behavioral procedures for pretesting intra-amygdala infusions of ifenprodil for LTM testing only.
