Anatomy of the cerebellum numerous neuron in the brain (roughly 70% of all neurons in the brain and spinal cord, combined). Golgi cells provide inhibitory feedback to granule cells, forming a synapse with them and projecting an axon into the molecular layer. The local field potentials of the neocortex and cerebellum oscillate coherently at (6–40 Hz) in awake behaving animals. These appear to be under the control of output from the cerebral cortex. This output would be mediated by a pathway from layer 5/6 neurons in the neocortex through that project either to the pons or the inferior olive. If through the pons this
Lateral hypothalamus Lateral hypothalamus The lateral hypothalamus, also called the lateral hypothalamic area, contains the primary orexinergic nucleus within the hypothalamus that widely projects throughout the nervous system; this system of neurons mediates an array of cognitive and physical processes, such as promoting feeding behavior and arousal, reducing pain perception, and regulating body temperature, digestive functions, and blood pressure, among many others. Clinically significant disorders that involve dysfunctions of the orexinergic projection system include narcolepsy, motility disorders or functional gastrointestinal disorders involving visceral hypersensitivity (e.g., irritable bowel syndrome), and eating disorders. The neurotransmitter glutamate and the endocannabinoids (e.g., anandamide) and the orexin
