What are the functional regions of the cerebellum?
Label the input to cerebellum
What structures are responsible for inputs to cerebellum?
Label the output from cerebellum
Label the outputs to cortical motor system
Label the outputs to brainstem
Explain the vestibulocerebellar circuits
Label the colors
What are the neurons in order for the posterior and anterior spinocerebellar tracts as well as the cunocerbellar tract?
Which of the posterior and anterior spinocerebellar tracts as well as the cunocerbellar and rostrospinal tracts are crossed/uncrossed/double crossed?
What are the inputs and outputs of the spinocerebellar circuits? What do they do?

What connects the lateral hemispheres of cerebellum with the cortex?
cerebrocerebellum
List location and function of cerebrocerebellum
List cerebrocerebellar tracts
What are these?
Label the colors and explain
What are the cognitive and emotional functions of the cerebrocerebellum?
Label
Summarize the functions of the cerebellum, what are they?
For the functional division, vestibulocerebellum, 1) where does it receive input, 2) send output to, 3) output reaches motor neurons via?
For the functional division, spinocerebellum, 1) where does it receive input, 2) send output to, 3) output reaches motor neurons via?
For the functional division, cerebrocerebellum, 1) where does it receive input, 2) send output to, 3) output reaches motor neurons via?
What are the typical deficits from cerebellar lesions?
Explain effects of cerebellar lesions in 1) flocculonodular lobe, 2) spinocerebellum, 3) cerebrocerebellumand intermediate zone
Explain ataxia (somatosensory vs cerebellar)
What are the deficits from lesions to vestibulocerebellum?
How is knee and ankle coordination affected due to cerebellar lesions?
How is reaction time affected due to cerebellar lesions?
What movement can test for dysmetria?
How are rapid alternating movements affected due to cerebellar lesions?
How is the time required to initiate a movement affected due to cerebellar lesions?
Do patients with cerebellum damage make significant improvements?
No, focus on maintenance
What are the signs (and explain them) of cerebellar lesions in vestibulocerebellum?
What are the signs (and explain them) of cerebellar lesions in spinocerebellum?
What are the signs (and explain them) of cerebellar lesions in cerebrocerebellum?
Explain the effects on muscle strength, bulk, involuntary muscle contraction, muscle tone, movement speed & efficiency, and postural control due to complete severance of the peripheral nerve
Explain the effects on muscle strength, bulk, involuntary muscle contraction, muscle tone, movement speed & efficiency, and postural control due to UMN lesions
Explain the effects on muscle strength, bulk, involuntary muscle contraction, muscle tone, movement speed & efficiency, and postural control due to parkinson’s disease
Explain the effects on muscle strength, bulk, involuntary muscle contraction, muscle tone, movement speed & efficiency, and postural control due to Huntington’s disease
