Staying awake for dinner: hypothalamic integration of sleep, feeding, and circadian rhythms
Abstract
Daily patterns of sleep and wakefulness are inextricably linked to the regulation of feeding and energy metabolism. Both are affected by homeostatic as well as circadian drives, and both are tightly linked to thermoregulation. In this chapter, we review the basic drain circuitry that regulates sleep and wakefulness, including the flip-flop switch relationship of the arousal system and the ventrolateral preoptic sleep-promoting neurons. We then examine the role of the orexin/hypocretin neurons, which stabilize the switch while driving both wakefulness and foraging for food. We also review the role of the subparaventricular nucleus and the dorsomedial nucleus of the hypothalamus in circadian integration and modulation of both feeding and wake-sleep patterns.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
