The hypothalamic arcuate nucleus (Arc) is a target site for signals regulating energy homeostasis. The orexigenic hormone ghrelin directly activates neurons of the medial arcuate nucleus (ArcM) in rats. Nitric oxide (NO) is a neuromodulator implicated in the control of food intake and body weight. NO is produced by nitric oxide synthase (NOS) and induces(More)
The pancreatic hormone amylin decreases food intake via activation of area postrema (AP) neurons. We investigated whether amylin's potency to reduce food intake and to induce c-Fos expression in the AP/nucleus of the solitary tract region is affected by the feeding conditions and specifically by the macronutrient composition of the diet. Whereas a low dose(More)
