Tract | Origin | Peduncle | Termination | Fiber types |
ventral external arcuate | arcuate nucleus | ICP | posterior lobe hemisphere | corticospinal collaterals |
reticulocerebellar | reticular gray matter | ICP | contralateral anterior lobe of vermis | cutaneous stimuli via spinothalamics |
olivocerebellar | inferior olivarry nucleus | ICP contralateral | vermis and lateral hemisphere (climbing fibers) | reticular gray, basal ganglia, cerebral cortex |
vestibulocerebellar | vestibular nuclei | ICP | flocculonodular lobe (ips) | vestibular input |
pontocerebellar | pontine nuclei | MCP | vermis posterior lobe contralateral | input from muscle/tendon/joint and vestibular/visual/auditory |
ventral spinocerebellar | nucleus proprius | SCP | vermis anterior ipsilateral | proprioceptive and tactile |
tectocerebellar | Sup and Inf colliculi | SCP | vermis ant and post | visual and auditory impulses |
fastigial | fastigial nucleus | ICP | vestibular nucleus, cervical ventral horn | coordinate neck mm with eye movements |
interposed | interposed nuclei | SCP | medulla nuclei | speech - tonus, coordination, stabilization |
dentate | dentate nucleus | SCP | red nucleus, tegmentum, dorsal thalamus | sensorimotor modulation |
Dorsal spinal cerebellar | nucleus thoracis | ICP | vermis | proprioceptive/tactile for sacral/lumbar/thoracic |
dorsal external arcuate | lateral cuneate nucleus | ICP | vermis (ant/post lobe) | proprioceptive/tactile for neck and upper limb |
