Previous results indicate that pretraining peripheral injections of any of several adrenergic receptor antagonists can attenuate retrograde amnesia. The present experiment was an attempt to determine if the attenuation of amnesia was due to a blocking of peripheral sympathetic norepinephrine release. This experiment examined the effects on cortical stimulation-induced amnesia of pretreatment with bretylium, a drug which blocks release of norepinephrine from sympathetic nerve endings. The findings indicate that bretylium does not itself affect retention performance, nor does bretylium attenuate the production of retrograde amnesia.
