TL;DR
The findings indicate that adrenergic antagonists attenuate amnesia produced by amygdala stimulation for visual discrimination training, and suggest that Adrenergic mechanisms may be involved in the production of retrograde amnesia.
Abstract
Subseizure electrical stimulation of the amygdala produced retrograde amnesia for a visual discrimination shock-motivated task. Animals pretreated with the alpha-adrenergic antagonist phenoxybenzamine, or the beta-adrenergic antagonist propranolol, did not develop amnesia. The findings indicate that adrenergic antagonists attenuate amnesia produced by amygdala stimulation for visual discrimination training. These results are consistent with previous evidence indicating that adrenergic antagonists attenuate the amnesias produced by a variety of agents, and thus, suggest that adrenergic mechanisms may be involved in the production of retrograde amnesia.

A selective review of the literature on the effect of electrical stimulation of the brain on learning and memory processes is presented, and tentative suggestions are advanced relating these effects to processes associated with storage and retrieval of information.

The results support a role for an amygdala beta-adrenergic system in memory processes and time-dependent and dose-dependent decreases in retention of the task.
Behavioral BiologyPosttraining brain norepinephrine concentrations: Correlation with retention performance of avoidance training and with peripheral epinephrine modulation of memory processing
190 Citations1978Paul E. Gold, Roderick van Buskirk
The findings reported here indicate that the effects on retention of epinephrine injections and of footshock level are closely related to transient posttraining decreases in whole brain norepinephrine concentrations, and suggest that memory modulation may involve neuroendocrine mechanisms that include the central noradrenergic system.
Behavioral BiologyEnhancement and impairment of memory processes with post-trial injections of adrenocorticotrophic hormone
189 Citations1976Paul E. Gold, Roderick van Buskirk
The general view that ACTH may modulate memory storage processing of recent information is supported, and the possibility that other post-trial treatments which facilitate or impair memory processes may act via hormonal mechanisms is suggested.
Hormones and BehaviorEffects of posttrial hormone injections on memory processes
160 Citations1976Paul E. Gold, Roderick van Buskirk
Results are consistent with the view that hormonal consequences of an experience, particularly epinephrine, norepinephrine and ACTH release, may normally have a modulatory influence on memory processes in untreated animals and it is therefore possible that other posttrial treatments which enhance or impair later retention performance may act through hormonal mechanisms.

The findings extend and corroborate the previous evidence suggesting that hormonally mediated central noradrenergic activity may underlie retrograde amnesia and enhancement of memory processes and suggest that memory storage processing may be modulated by normal post-training hormonal and central aminergic responses to training.

There may be a common neurobiological mechanism underlying the amnesias produced by many treatments in animals earlier treated with the alpha-adrenergic antagonist phenoxybenzamine, and PBZ-treated animals did not develop amnesia.
