WebNPY/AgRP neurons and POMC/CART neurons make up two groups of neurons in the arcuate nucleus that are centrally involved in the neuroendocrine function of feeding. Medial neurons utilize NPY peptides as neurotransmitters to stimulate appetite, and lateral neurons utilize POMC/CART to inhibit appetite. [2] WebDec 1, 2014 · The actions of AgRP and POMC neurons are brought about by projections to other brain sites, one notable structure being the paraventricular nucleus (Figure 3). MC4R-expressing neurons, a subset of the neurons in this complex neural hub, play a major role in mediating the effects of the melanocortin system on hunger.
WebJul 10, 2015 · The putative POMC neurons generally showed opposite effects to the AgRP neurons. The results of these electrode recordings in awake mice thus suggest that AgRP and POMC neurons together maintain a drive to seek out food sources as energy reserves fall, and to refrain from doing so when energy reserves are plentiful.
