Abstract

The present study examined the relative importance of α- and β-adrenoceptors in the memory modulatory effects of epinephrine. Posttraining epinephrine administration enhancef retention performance of a one-trial inhibitory avoidance respone. Further pretraning injections of a variety of adrenoceptor antagonists, including selective α₁-,α₂, β₁- and /or β₂-adrenoceptor antagonists, attenuated the retention enhancing effects of posttraining epinephrine. These results suggest that α- and β-adrenoceptors of both subtypes are involved in the memory-modulating effects of epinephrine.
