Oxytocin, Feeding, and Satiety
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 ...
متن کاملSerotonin-3 receptors in gastric mechanisms of cholecystokinin-induced satiety.
OUR UNDERSTANDING OF THE CONTROLS of food intake has increased substantially during the last 30 years. Important in this has been the recognition of the meal as a controlled, physiologically relevant unit of energy intake. During a meal, ingested nutrients accumulate in the stomach and gradually pass to the small intestine. The gastrointestinal presence of nutrients stimulates the release of pe...
متن کاملThe Effect of Cognitive-behavior Modification and Feeding Behavior on Serotonin Levels and Depression Symptoms
Background: Depression includes negative interpretations of events, dislike of the self, and negative appraisal of the future. Objectives: The present study was conducted to investigate the effect of educational programs of cognitive-behavior modification and feeding behavior on serotonin levels and depression symptoms in university students. Materials & Methods: This quasi-experimental study...
متن کاملSerotonin depresses feeding behaviour in ants.
Feeding behaviour is a complex functional system that relies on external signals and the physiological state of the animal. This is also the case in ants as they vary their feeding behaviour according to food characteristics, environmental conditions and - as they are social insects - to the colony's requirements. The biogenic amine serotonin (5-HT) was shown to be involved in the control and m...
متن کاملIdentification of a Brainstem Circuit Controlling Feeding.
Hunger, driven by negative energy balance, elicits the search for and consumption of food. While this response is in part mediated by neurons in the hypothalamus, the role of specific cell types in other brain regions is less well defined. Here, we show that neurons in the dorsal raphe nucleus, expressing vesicular transporters for GABA or glutamate (hereafter, DRNVgat and DRNVGLUT3 neurons), a...
