摘要：

In mammals, a number of hypothalamic neuropeptides have been implicated in stress-induced feeding disorders. Recent studies in anurans suggest that stress-related neuropeptides may act on elemental aspects of visuomotor control to regulate feeding. Corticotropin-releasing hormone (CRH) and alpha-melanocyte-stimulating hormone, potent anorexic peptides in mammals, inhibit visually-guided prey-catching in toads. Neuropeptide Y (NPY), anorexic peptide in mammals, may be an important neuromodulator in inhibitory pre-tectal-tectal pathways involved in distinguishing predator and prey. Melanocortin, NPY and CRH neurons project onto key visuomotor structures within the amphibian brain, suggesting physiological roles in the modulation of prey-catching. Thus, neuropeptides involved in feeding behavior in mammals influence the efficacy of a visual stimulus in releasing prey-catching behavior. These neuropeptides may play an important role in how frogs and toads gather and process visual information, particularly during stress. (C) 2002 Elsevier Science Inc. All rights reserved.
