The review article summarizes the results obtained in the author's laboratory during the last few years concerning the action of number of neurohormones such as ACTH, vasopressin, oxytocin, TRH and TRH analogues, human chorionic gonadotropin (HCG) LH-RH, gastrin and gastrin C-terminal fragments and cholecystokinin octapeptide on certain behavioural reactions and brain transmitters. The results obtained suggests that in some of the behavioural reactions elicited by these peptide hormones are brought about by modulatory action of these peptide on brain transmitters. These neurohormones, including gastrointestinal peptide hormones have a time dependent, locus and transmitter specific action on the brain function.

Neuropeptides play an important role in the regulation of feeding behavior and obesity. The mechanisms for controlling food intake involve a complicated interplay between peripheral systems (including gustatory stimulation, gastrointestinal peptide secretion, and vagal afferent nerve responses) and central nervous system (CNS) neuropeptides and/or monoamines. These neuronal systems include neuropeptides (CRH, opioids, neuropeptide-Y (NPY) and peptide YY (PYY), vasopressin and oxytocin, CCK, and leptin) and monamines (serotonin, dopamine, norepinephrine). In addition to regulating eating behavior, a number of CNS neuropeptides participate in the regulation of neuroendocrine pathways. Thus, clinical studies have evaluated the possibility that CNS neuropeptide alterations may contribute to dysregulated secretion of the gonadal hormones, cortisol, thyroid hormones and growth hormone in the eating disorders. Most of the neuroendocrine and neuropeptide alterations apparent during symptomatic episodes of AN and BN tend to normalize after recovery. This observation suggests that most of the disturbances are consequences rather than causes of malnutrition, weight loss and/or altered meal patterns. Still, an understanding of these neuropeptide disturbances may shed light on why many people with AN or BN cannot easily "reverse" their illness and even after weight gain and normalized eating patterns, many individuals who have recovered from AN or BN have physiological, behavioral and psychological symptoms that persist for extended periods of time.
