Hormonal and neural mechanisms of food reward, eating behaviour and obesity
With rising rates of obesity, research continues to explore the contributions of homeostatic
and hedonic mechanisms related to eating behaviour. In this Review, we synthesize the …

Hypothalamic tanycytes are an ERK-gated conduit for leptin into the brain
Leptin secreted by adipocytes acts on the brain to reduce food intake by regulating neuronal
activity in the mediobasal hypothalamus (MBH). Obesity is associated with resistance to high …

Lateral hypothalamic orexin glucose-inhibited neurons may regulate reward-based feeding by modulating glutamate transmission in the ventral tegmental area
SB Teegala, Z Sheng, MS Dalal, PR Hirschberg… - Brain research, 2020 - Elsevier

Leptin Receptor− Deficient Obese Zucker Rats Reduce Their Food Intake in Response to a Systemic Supply of Calories From Glucose
M Gilbert, C Magnan, S Turban, J André… - Diabetes, 2003 - Am Diabetes Assoc
It has been established that leptin exerts a negative control on food intake, allowing one to
maintain stable caloric intake over time. The aim of the present study was to investigate …

Hedonic eating: sex differences and characterization of orexin activation and signaling
L Buczek, J Migliaccio, GD Petrovich - Neuroscience, 2020 - Elsevier
Palatable taste can stimulate appetite in the absence of hunger, and individual differences in
hedonic eating may be critical to overeating. Women are more prone to obesity and binge …

Ghrelin acts as an interface between physiological state and phasic dopamine signaling
Brief, high-concentration (phasic) spikes in nucleus accumbens dopamine critically
participate in aspects of food reward. Although physiological state (eg, hunger, satiety) and …
