Anatomy of the cerebellum to describe the cellular structure is to begin with the inputs and follow the sequence of connections through to the outputs. The four deep nuclei of the cerebellum are the dentate, emboliform, globose, and fastigii nuclei and they act as the main centers of communication, sending and receiving information to and from specific parts of the brain. In addition, these nuclei receive both inhibitory and excitatory signals from other parts of the brain which in turn affect the nuclei's outgoing signals.(The globose and the emboliform nuclei make up the interposed nucleus). The cytoarchitecture (cellular organization) of the cerebellum is highly
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
