    Summary · context
    The content of norepinephrine (NE) and serotonin (5-HT) in the right and left halves of the brain of rats was compared in the norm, during the development of defensive two-way avoidance conditioned reflexes (TWACR), and with the administration of peptides which influence learning and memory, namely…

    Summary
    The systemic administration of DG-AVP, ACTH4-7 pro-gly-pro, and dalargin essentially did not alter the 5-HT content, and decreased the NE content in the cortex and in the rest of the brain. In the process the NE content of the right and left hemisphere evened out.
