摘要

Food is critical for all animal species. Its temporal availability is a relevant signal fororganizing behavioral and physiological parameters. When food is restricted to a fewhours per day, rats, mice, and other mammals exhibit anticipatory activity before meal-time (food-anticipatory activity). There is considerable evidence suggesting that thisanticipation is mediated by a food-entrainable oscillator (FEO) with circadian proper-ties, but located outside the suprachiasmatic nucleus of the hypothalamus (the light-entrainable oscillator). However, the locus of the FEO as well as the mechanisms bywhich food entrainment occurs is unclear. In this review, we summarize data aboutthe potential input pathways to the FEO and propose a model for understanding itas a network of interconnected brain structures entrained by fluctuation of differenthumoral signals.
