Memory formation: evidence for a specific neurochemical system in the amygdala

M Gallagher, BS Kapp, RE Musty, and PA Driscoll

beta-Adrenergic antagonists injected into the amygdala complex of rats trained in a passive avoidance task produced time-dependent and dose-dependent decreases in retention of the task. In addition, the effects observed with beta-adrenergic antagonists were both stereospecific and reversed by norepinephrine. The results support a role for an amygdala beta-adrenergic system in memory processes.
