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.
