What is VMH syndrome?
Electrolytic lesions of the ventromedial hypothalamus (VMH) produce an obesity syndrome characterized by hyperphagia, adiposity, and heightened parasympathetic tone. Experiments were conducted to evaluate the possibility that these symptoms arise from damage to distinct and separated loci within the hypothalamus.
