Hunger and satiety: one brain for two?
UNDERSTANDING THE PHYSIOLOGICAL controls of eating and developing effective pharmacological tools to reduce eating has never been more important. The modern world faces an unprecedented obesity epidemic, and the current treatment strategies are rather unsuccessful. One possible solution may be a combination or cocktail therapy. Obesity control research has been more focused on “long-term” adipo...
متن کاملHunger and Satiety Gauge Reward Sensitivity
Many of the neurocircuits and hormones known to underlie the sensations of hunger and satiety also substantially alter the activity of the dopaminergic reward system. Much interest lies in the ways that hunger, satiety, and reward tie together, as the epidemic of obesity seems tied to the recent development and mass availability of highly palatable foods. In this review, we will first discuss t...
متن کاملNeural Control of Hunger, Appetite, and Satiety **
Hunger, appetite, and satiety are often regarded as problems in the physiology of digestion. In recent years, however, they have been studied more and more commonly as functions of the brain. This latter point of view, i.e., neurophysiology, is used in the paper which follows, and the regulation of food intake is here described in terms of mechanisms and reactions that characterize the nervous ...
متن کاملOxytocin, 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 کاملFrom hunger to satiety: reconfiguration of a feeding network by Aplysia neuropeptide Y.
A shift in motivational state often produces behavioral change, but the underlying mechanisms are poorly understood. In the marine mollusc, Aplysia californica, feeding-induced transition from a hunger to satiation state leads to a slowdown and an eventual termination of feeding. Because the multifunctional feeding network generates both ingestion and the competing response, egestion, it is pos...
