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
Lateral hypothalamus substructures, including the rostral ventromedial medulla, rostral ventrolateral medulla, nucleus ambiguus, solitary nucleus, spinal trigeminal nucleus, pontine micturition center, ventral respiratory group, and pontine respiratory group), area postrema, and dorsal nucleus of vagus nerve. Cannabinoid receptor 1 (CB1) is colocalized on orexinergic projection neurons in the lateral hypothalamus and many output structures, where the CB1 and orexin receptor 1 (OX1) receptors physically and functionally join together to form the CB1–OX1 receptor heterodimer. There is substantial anatomical and functional overlap and systemic cross-talk between the endocannabinoid system and orexin system within the central nervous system. Through the diverse outputs of the
