Orexin-A does not stimulate food intake in old rats.
Aging is associated with a progressive decrease in appetite and food intake. Both A and B orexins, expressed in specific neurons of the lateral hypothalamic area, have been implicated in the regulation of sleep and feeding. In this study, the stimulatory effect of intracerebroventricular administration of the orexins on food intake was compared between young (4-mo-old) and old (25- to 27-mo-old...
متن کاملHypothalamic hypoactivity prevented but not reversed by subdiaphragmatic vagotomy.
Parasagittal hypothalamic knife cuts produce a syndrome which includes obesity and hypoactivity . when the subdiaphragmatic vagi were cut at the same time as the brain cuts were made, both the obesity and the hypoactivity were prevented. This suggested that both the obesity and the hypoactivity are mediated by vagal hyperactivity, m contrast, however, when the subdiaphragmatic vagotomy was done...
متن کاملBilateral adrenalectomy or subdiaphragmatic vagotomy on gastric tissue histamine concentration in albino rats.
Gastric tissue histamine concentration was determined 14 days after mock subdiaphragmatic vagotomy, subdiaphragmatic vagotomy, mock bilateral adrenalectomy and bilateral adrenalectomy in four different groups of animals and the results were compared with those of control rats. The results show that neither of the experimental situations of mock subdiaphragmatic vagotomy, subdiaphragmatic vagoto...
متن کاملMeal-synchronized CEA in rats: effects of meal size, intragastric feeding, and subdiaphragmatic vagotomy.
Within a feeding schedule of intermittent food access, large meals have the ability to induce activity at the same time the next day [circadian ensuing activity (CEA)]. In these experiments, we evaluated the minimum meal size necessary to induce CEA and whether oral-pharyngeal factors and afferent vagal activity played necessary roles in the induction of the underlying process. In experiment 1,...
متن کاملCafeteria diet-induced sleep is blocked by subdiaphragmatic vagotomy in rats.
Feeding rats a cafeteria diet results in increased food intake and excess sleep. Furthermore, vagal afferent activity is altered by a variety of gastrointestinal factors, and vagal stimulation can induce sleep. We investigated, therefore, the hypothesis that the vagal nerve plays a critical role in mediating the sleep-inducing effects of cafeteria feeding. We examined the effects of a cafeteria...
