Amygdala central nucleus lesions attenuate acoustic startle stimulus-evoked heart rate changes in rats.

abstract：:Rats were exposed to shock-paired cues immediately after training on an appetitive preference task. Elevated levels of freezing in and active avoidance of the shock-paired compartment were observed, and memory for the appetitive task was improved when tested 24 hr later. Intra-amygdala muscimol injected before the pos...
