1 C. The arcuate neurons shown in part B project to multiple regions of the hypothalamus. The paraventricular nucleus (PVN) is a convergence zone for many signals involved in energy (and fluid) balance. Neurons in this nucleus synthesize several peptides that decrease food intake, including corticotropin-releasing hormone (CRH), thyrotropin-releasing hormone (TRH), and oxytocin (OXY). The perifornical area (PFA) and lateral hypothalamic area (LHA) contain neurons that synthesize orexins and melanin concentrating hormone (MCH), peptides that stimulate food intake.
