Endogenous Opiate Systems May Modulate Learning and Memory
It is becoming increasingly realized that the endogenous opiate peptides have numerous effects on a wide range of behaviors and physiological conditions. Some of these effects may reflect the multiple physiological roles these peptides might play other than the ones related to pain perception; these additional roles may, in fact, be of more importance to the organism than the antinociceptive function with which the peptides were originally associated. Learning and memory processes might represent important functions modulated by the peptides.
