Fulleret al. (Reports, 23 May 2008, p. 1074) reported that the dorsomedial hypothalamus contains aBmal1-based oscillator that can drive food-entrained circadian rhythms. We report that mice bearing a null mutation ofBmal1exhibit normal food-anticipatory circadian rhythms. Lack of food anticipation inBmal1–/–mice reported by Fulleret al. may reflect morbidity due to weight loss, thus raising questions about their conclusions.
