夜间动物白天食物和水的限制使血浆皮质类固醇浓度和体温的昼夜节律周期发生相移。这些变化的节律在下丘脑腹内侧损伤的动物中不会持续存在，这与我们之前报道的在视交叉上核损伤的动物中持续存在这种变化的节律相反。这些结果表明，腹内侧下丘脑可能是介导的昼夜节律反应的食物同步的解剖位点。
Daytime restriction of food and water availability in nocturnal animals phase-shifts the circadian periodicity of plasma corticosteroid concentrations and body temperature. These shifted rhythms do not persist in animals with lesions of the ventromedial hypothalamus, in contrast to our previous reports of persistence of such shifted rhythms in animals with lesions of the suprachiasmatic nuclei. These findings suggest that the ventromedial hypothalamus may be the anatomical locus which mediates the circadian response to food synchronization.
