Peptides in Neurobiology

Elucidation of the important roles played by peptides as hypothalamic-adenohypo- physeal releasing factors, or regulatory hormones, has in recent years led to the recognition that peptides may also be of significance as intercellular messengers in other regions of the nervous system. In this regard, it is interesting that Sub- stance P, which has been proposed as a putative neurotransmitter in the spinal cord, was rediscovered by Leeman and her co-workers during their search for the cortico...
