Shock reactivity in rats with pretraining BLA lesions and temporary inactivation of the CEA before training (Experiment 3). Mean percentage of activity (±SEM) before the first conditioning trial (Pre) and during the first 2-sec shock (Shock) during the conditioning session. Data are shown for rats with pretraining sham surgeries receiving saline in the CEA before training (SH-SAL: solid squares), pretraining sham surgeries receiving muscimol in the CEA before training (SH-MUS: open squares), pretraining NMDA lesions of the BLA receiving saline in the CEA before training (BLA-SAL: solid circles), or pretraining NMDA lesions of the BLA receiving muscimol in the CEA before training (BLA-MUS: open circles).
