Abstract

Information processing in the brain largely involves communication among neurons through the release of neurotransmitters at synapses. In addition to the amino acids and biogenic amines, it now appears that neuropeptides may also mediate inter-neuronal communications to coordinate a variety of neuroendocrine and behavior functions. The list of neuropeptides as putative modulators or mediators in the brain is growing steadily along with the diversity of physiological functions ascribed to them at various peripheral and central sites. In addition, recent neurochemical and morphological studies indicate that single neurons might contain and release more than one transmitter (Hökfelt et al., 1984; Chan-Palay and Palay, 1984). Several neuropeptides have been shown to coexist intraneuronally with the classical neurotransmitters—monoamines and acetylcholine. Thus, the emerging possibility that more than one neurotransmitter and neuromodulator may be coreleased and coact has prompted a reexamination of neuronal communications controlling the basic functions of reproductive and appetitive behaviors.
