Anatomy of the cerebellum to the cerebellum, in two categories consisting of mossy and climbing fibers, respectively. Mossy fibers can originate from the pontine nuclei, which are clusters of neurons located in the pons that carry information from the contralateral cerebral cortex. They may also arise within the spinocerebellar tract whose origin is located in the ipsilateral spinal cord. Most of the output from the cerebellum initially synapses onto the deep cerebellar nuclei before exiting via the three peduncles. The most notable exception is the direct inhibition of the vestibular nuclei by Purkinje cells. During the early stages of embryonic development, the brain starts
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
