Cerebellum (General) Flashcards
General Pathway of Cerebellar Processing
- Inputs go to cerebellar cortex
- Cortex projects to deep cerebellar nuclei
- Deep cerebellar nuclei project back out of cerebellum
Function of the Cerebellum
Detect differences between intended action and actual action and promote error reduction
Information from one side of the body is processed on the ______ side of the cerebellum
Ipsilateral
Outputs from the cerebellum mostly project from…
Deep Cerebellar Nuclei
Output from the vermis is processed by…
Fastigial Nuclei
Output from the intermediate zone is processed by…
Interposed Nuclei (Globose + Emboliform Nuclei)
Output from the cerebrocerebellum is processed by…
Dentate Nuclei
Outputs to this set of nuclei largely bypass the deep cerebellar nuclei
Vestibular Nuclei
This information is carried by the superior cerebellar peduncle
Major output to thalamus and red nucleus
This information is carried by the middle cerebellar peduncle
Major input from cerebral cortex (via pontine nuclei)
This information is carried by the inferior cerebellar peduncle
Inputs from spine, medulla, and vestibular system;
outputs to some brainstem nuclei
Information in and out of the cerebellum must ______
Decussate (to maintain ipsilateral representation)
Climbing fibers are inputs to cerebellum from…?
Inferior Olivary Nuclei
General inputs to cerebellum are called…?
Mossy Fibers
The majority of the human cerebellum gets information from where?
Association Cortices
Outputs through the inferior cerebellar peduncle relates to…?
Balance and Eye Movement Stability
The majority of outputs from cerebellum leave through the…?
Superior Cerebellar Peduncle
Function of cerebellar outputs to red nucleus
Provides feedback to the inferior olivary nucleus
Function of outputs to VL complex (thalamus)
Provides movement information to motor/pre-motor cortex
Function of outputs to superior colliculus
Provides information for voluntary gaze
Cortical areas project to cerebellum via (A), and receive projections from it via (B)
(A) Pontine nuclei
(B) Thalamus
These cells provide the primary output from the cerebellum
Purkinje Cells
Stellate, basket, and Golgi cells are examples of these kinds of cerebellar cells
Inhibitory interneurons
Mossy fibers pass their inputs to…?
Granule Cells
Purkinje cell firing pattern
Intrinsically active and inhibitory outputs to deep cerebellar nuclei
The deep cerebellar nuclei provide inputs to _____
Motor neurons (typically upper)
Long-term changes in cerebellar activity occur at this cerebellar processing layer
Deep cerebellar nuclei
