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
Anatomy of the cerebellum the face; it can also cause hearing impairment. Moreover, it could cause an infarct of the cerebellopontine angle. This could lead to hyperacusia (dysfunction of the stapedius muscle, innervated by CN VII) and vertigo (wrong interpretation from the vestibular semi-circular canal's endolymph acceleration caused by alteration of CN VIII). The PICA branches off the lateral portion of the vertebral arteries just inferior to their junction with the basilar artery. Before reaching the inferior surface of the cerebellum, the PICA sends branches into the medulla, supplying blood to several cranial nerve nuclei. In the cerebellum, the PICA supplies blood to the
