Study Notes
Cerebellar Structures and Function
- Cerebellar Cortex: Receives inputs from both the spinal cord and the cortex, enabling it to integrate sensory and motor information.
- Pontocerebellar Pathway: Carries information about planned movements from the pontine nuclei to the opposite side of the cerebellar cortex.
- Dentate Nucleus: The primary output nucleus of the cerebellum that projects to the primary and premotor cortex for coordinating voluntary movement.
- Flocculonodular Lobe: Receives input from the vestibular system, responsible for postural control and balance.
- Anterior Lobe: Primarily involved in eye movements and control of proximal and axial muscles.
- Deep Cerebellar Nuclei: The primary efferent nuclei of the cerebellum (dentate nucleus, interposed nuclei, fastigial nucleus) which project to various brain structures for regulating motor control.
