RT Journal Article SR Electronic T1 Memory formation: evidence for a specific neurochemical system in the amygdala JF Science JO Science FD American Association for the Advancement of Science SP 423 OP 425 DO 10.1126/science.20664 VO 198 IS 4315 A1 Gallagher, M A1 Kapp, BS A1 Musty, RE A1 Driscoll, PA YR 1977 UL http://science.sciencemag.org/content/198/4315/423.abstract AB 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.
