A hindbrain dopaminergic neural circuit prevents weight gain by reinforcing food satiation
The neural circuitry mechanism that underlies dopaminergic (DA) control of innate feeding
behavior is largely uncharacterized. Here, we identified a subpopulation of DA neurons …

[HTML][HTML] Anterior paraventricular thalamus to nucleus accumbens projection is involved in feeding behavior in a novel environment
Foraging food in a novel environment is essential for survival. Animals coordinate the
complex motivated states and decide whether to initiate feeding or escape from unfamiliar …

A D2 to D1 shift in dopaminergic inputs to midbrain 5-HT neurons causes anorexia in mice
Midbrain dopamine (DA) and serotonin (5-HT) neurons regulate motivated behaviors,
including feeding, but less is known about how these circuits may interact. In this study, we …

[PDF][PDF] Accumbal D1R neurons projecting to lateral hypothalamus authorize feeding
Feeding satisfies metabolic need but is also controlled by external stimuli, like palatability or
predator threat. Nucleus accumbens shell (NAcSh) projections to the lateral hypothalamus …

Zona incerta dopamine neurons encode motivational vigor in food seeking
Energy deprivation triggers food seeking to ensure homeostatic consumption, but the neural
coding of motivational vigor in food seeking during physical hunger remains unknown. Here …

Background: Dopamine (DA) signalling in the brain is necessary for feeding behaviour, and
alterations in the DA system have been linked to obesity. However, the precise role of DA in …

Insulin in the ventral tegmental area reduces hedonic feeding and suppresses dopamine concentration via increased reuptake
Mesolimbic dopamine (DA) signaling has been implicated in the incentive, reinforcing and
motivational aspects of food intake. Insulin receptors are expressed on dopaminergic …

[HTML][HTML] Overlapping representations of food and social stimuli in VTA dopamine neurons
Dopamine neurons of the ventral tegmental area (VTA DA) respond to food and social
stimuli and contribute to both forms of motivation. However, it is unclear if the same or …
