[edit] Gross anatomy

Column 1 Column 2 (memorize)
What are the 3 rostrocaudal divisions of the cerebellum? Anterior lobe, Posterior lobe, and Floculonodular lobe.
What fissure divides the anterior and posterior lobe? Primary fissure
What fissure divides the floculonodular and posterior lobe? Posterolateral fissure
What are the 3 sagittal divisions? Vermis, paravermis, and lateral hemispheres.
What does the vermis contain? The midline of the anterior and posterior lobes.
What does the paravermis contain? Most of the anterior lobe and part of the posterior lobe.
What does the hemispheres contain? The laterior portion of the posterior lobe.
What is the input and output of the flocculonodular lobe? (Input) Vestibular ganglion, (Output) vestibular nuclei.
What innervates the vermis and the paravermis? Ascending systems from the spinal cord, the spinocerebellar, and cuneocerebellar tracts.
What is the function of the vermis and the paravermis? Coordination of movement underlying gait.
What are the vermis and paravermis also referred to as? Spino-cerebellum.
The lateral hemispheres form part of a circuit that originates in the __(1)__, synapses on neurons of the __(2)__, and terminates in the __(3)__. (1) Frontal and parietal lobes, (2) pontine nucleus, (3) contralateral cerebellar hemispheres.
The lateral hemispheres are also called what? Ponto-cerebellum.
What region(s) of the cerebellar cortex sends axons outside of the of the cerebellum? Only the flocculonodular lobe.
What are the deep cerebellar nuclei (and what regions innervate them)? Dentate nuclei (lateral hemispheres), interposed nuclei (paravermis), and fastigial nuclei (vermis).
Name the cerebellar peduncles. Inferior, middle, and superior cerebellar peduncle.
What cerebellar peduncle does almost all communication between the cerebellum and the medulla and spinal cord travel? Inferior cerebellar peduncle.
What are the sources of afferents for the inferior cerebellar peduncle? Olivocerebellar afferents (from contralateral inferior olive), cuneocerebellar tract (from ipsilateral lateral cuneate nucleus), and Dorsal (posterior) spinocerebellar tract (from ipsilateral Clarke's nucleus).
What is the largest cerebellar peduncle? Middle cerebellar peduncle.
What cerebellar peduncle contains all the axons from the contralateral pontine nuclei that terminates in the cerebellar hemispheres? Middle cerebellar peduncle.
Which cerebellar peduncle carries the major output of the cerebellum through the deep cerebellar nuclei? Superior cerebellar peduncle.

[edit] Cerebellar circuitry

Column 1 Column 2 (memorize)
What are the output neurons? Purkinje cells
How many layers are there in the cerebellum? 3
What are the layers that are superficial and deep to the Purkinje cells? Molecular layer (ML) and granule cell layer (GCL).
What are basket cells? Inhibitory GABAergic interneurons from the molecular layer that synapse onto the Purkinje cell somata.
Where do Purkinje cells of the flocculonodular lobe send their axons? Directly to the vestibular nuclei. They are the only ones that don't first send the axons to the deep nuclei.
What are the excitatory interneurons of the cerebellar cortex? Granule cells.
Describe the dendrites of granule cells. There are only a few dendrites which end in complex "claws".
What is the input to a granule cell dendrite? A single mossy fibers.
What are the inhibitory interneurons of the cerebellar cortex? Basket cells, stellate cells, and golgi cells.
What are the afferent axons of the cerebellar cortex? Mossy fibers and climbing fibers.
