Question Answer
Functionmodulates movement, aids in coordination and balance
Inputcontralateral cortex via middle cerebellar peduncle, ipsilateral proprioceptive information via inferior cerebellar peduncle from spinal cord
Outputcontralateral cortex to modulate movement (purkinje cells --> deep nuclei of cerebellum --> contralateral cortex via superior cerebellar peduncle)
Lateral lesionsaffect voluntary movement of extremities, propensity to fall toward injured side
Medial lesionsinvolvement of midline structures (vermal cortex, fastigial nuclei) or flocculonodular lobe --> truncal ataxia (wide-based cerebellar gait), nystagmus, head tilting
