Abstract

Oxytocin neurons have a physiological role in food intake and energy balance. Central administration of oxytocin is powerfully anorexigenic, reducing food intake and meal duration. The central mechanisms underlying this effect of oxytocin have become better understood in the past few years. Parvocellular neurons of the paraventricular nucleus project to the caudal brainstem to regulate feeding via autonomic functions including the gastrointestinal vago-vagal reflex. In contrast, magnocellular neurons of the supraoptic and paraventricular nuclei release oxytocin from their dendrites to diffuse to distant hypothalamic targets involved in satiety. The ventromedial hypothalamus, for example, expresses a high density of oxytocin receptors but does not contain detectable oxytocin nerve fibers. Magnocellular neurons represent targets for the anorexigenic neuropeptide α-melanocyte stimulating hormone. In addition to homeostatic control, oxytocin may also have a role in reward-related feeding. Evidence suggests that oxytocin can selectively suppress sugar intake and that it may have a role in limiting the intake of palatable food by inhibiting the reward pathway.

  • Axonal release of oxytocin from the PVN may have effects on hedonic food consumption via dopaminergic mesolimbic neurons in the ventral tegmental area (VTA).

    “Axonal release of oxytocin from the PVN may also have effects on hedonic food consumption via dopaminergic mesolimbic neurons in the ventral tegmental area (VTA)(25, 26, 27).”

  • Oxytocin is released by dendrites of magnocellular neurons of the PVN and SON, and may reduce food intake in part via diffusion to the ventromedial nucleus, a satiety-regulating brain region rich in oxytocin receptors.

  • Vagal nerve fibers project to the PVN.

    “Additionally, it is known that vagal nerve fibers project to the PVN (Sabatier et al., 2013; Uvnas-Moberg et al., 2014), a brain region where oxytocin is produced”

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.
