Ventromedial nucleus of the hypothalamus the brain. VMH is also important in mammal play behaviour. Lesions to VMH along with the hippocampus, amygdala, the cerebellum, and the lateral hypothalamus are all linked to reduced play The VMHdm has a role in the male vocalizations and scent marking behaviors. The VMHvl plays a role in sexual behaviors in females (lordosis), thus stimulating their sexual arousal. Bilateral FOS expression in the VMH after repeated seizures is associated with alteration in the severity of flurothyl induced seizures in C57BL/6J mice that are not present in DBA/2J mice. Moreover, bilateral lesions of the VMH are able to block the
Ventromedial nucleus of the hypothalamus weight." This strongly substantiates the classification of VMN as the primary satiety center in the hypothalamus. It has also been found that lesions to the VMH in rats caused increased plasma insulin levels. Rats with a VMH lesion compared to normal rats overproduce a circulating satiety factor, to which the control rats can respond and rats with a VMH lesion cannot respond. A lesion to the VMH makes rats overproduce leptin, which they cannot respond to causing them to over eat, leading to obesity. Researchers looked at a series of twenty-one animals of various degrees of adiposity, with respect to
