[Protein-peptide complexes in the mechanisms of inborn and learned behavior patterns]

Protein-peptide complexes involved in learned and natural drinking behavioral patterns were comparatively analyzed in rats. Active immunization with protein-conjugated angiotensin II and beta-endorphin produces some behavioral responses. It is suggested that protein complexes of these peptides play a specific informational role in the systemic organization of learned behavior. The paper discusses whether these complexes perform an important function due to their conformational properties and their participation in the hierarchical organization of integrative processes in the nervous system.
