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
Anatomy of the cerebellum cerebellar cortex. Under resting conditions in animal experiments, groups of olivary neurons discharge synchronously at 5 to 10 Hz (impulses/s). In the cerebellar cortex, the response of Purkinje cells takes the form of complex spikes. The cerebellum send its projections back to the cerebral cortex via the Cerebellothalamic tract. The cerebellar lateral expansion, or the neocerebellum, may be associated with cognitive functions, and it is anatomically linked with the lateral prefrontal cortex. It shows greatest activity during speech, with a one-sided predominance consistent with a possible linkage (via the thalamus) with the motor speech area. When lesions occur in the
