Lesions of the lateral hypothalamic area (LHA) cause anorexia, whereas ablation of the paraventricular nucleus (PVN) cause a hyperphagic obesity syndrome. Consistent with these results, LHA neurons express the orexigenic neuropeptides MCH and orexin. PVN neurons produce several neuropeptides that are anorex-igenic when administered directly into the brain (CRH, TRH, oxytocin), in addition to their better known roles as endocrine regulators. LHA and PVN receive rich inputs from axons of NPY/AgRP and aMSH/CART-producing neurons in the arcuate nucleus. 

With the early application of stereotaxic surgery to neurological studies in experimental animals, Anand and Brobeck (1951) first reported that bilateral lesions of small nuclei in the hypothalamus could disrupt feeding behavior with medial hypothalamic lesions causing obesity and lateral lesions aphagia. In the latter syndrome, the lesioned animals would completely stop eating to the extent that if not maintained...
