Cerebellar Dysfunction

[Maria Dougherty]

I am a little bit confused on the functional division of the cerebellum (vestibulocerebellum, spinocerebellum, cerebrocerebellum) and well as it inputs and outputs. What references is this information coming from? because I am reading “Neuroanatomy through Clinical Cases” by Dr. Blumenfeld and I feel the information is not quite matching the information provided on the slides. For instance, in the book, inputs to the cerebellum are not specified to the location of the cerebellum. Am I the only one struggling with this part?

Hi Maria,
The resource for this material is the Lundy-Ekman Neuroscience textbook.

Here is an excerpt of the “Clinical Pearl” from the cerebellum section: “Input to the cerebellum is received from the cerebral cortex (via pontine nuclei), the vestibular apparatus, vestibular and auditory nuclei, and the spinal cord, via high-fidelity pathways (proprioceptive information) and internal feedback tracts (information regarding activity in spinal interneurons and in descending motor tracts). The output of the cerebellum is provided via connections that influence vestibulospinal, reticulospinal, rubrospinal, corticobrainstem, and corticospinal tracts.”

Table 11-5 (Neural connections of the cerebellar functional divisions) includes the function, inputs, and outputs for the spinocerebellum, vestibulocerebellum, and cerebrocerebellum.

Thank you! I’ll look into it.
