Document Summary
The cerebellum is connected to the brainstem through three fiber bundles: superior brachium conjunctivum, middle brachium pontis, inferior cerebellar penduncles restiform body. The lateral inferior surface of the cerebellum reveals the connections of the peduncles to the brainstem. Located ventrally, the middle and inferior peduncles appear as a bulging thick semicircular collar attached to the pontine ventrolateral brainstem. The cerebellar cortex near the midline (vermis), which receives all the input, plays an important role in the integration of vestibular data with the ongoing movement mechanism. After analyzing and synthesizing the received sensorimotor information, the cerebellum projects its corrective feedback predominantly to the opposite motor context, through the superior cerebellar peduncle. The spinal cord is the transmission link between the brain and the body. It transmits motor impulses from the brain to the visceral organs and muscles and carries sensory information, such as pain, touch, temperature, and proprioception, from the body to the brain.
