Which cerebellar peduncle is comprised largely of axons from neurons located in deep cerebellar nuclei?
A. Superior cerebellar peduncle.
B. Middle cerebellar peduncle.
C. Inferior cerebellar peduncle.
A) Superior cerebellar peduncle - the superior cerebellar peduncle contains largely cerebellar efferents, which originate from the deep cerebellar nuclei
T/F: The middle cerebellar peduncle is comprised of axons of basilar pontine nuclei neurons
True
What comprises the inferior cerebellar peduncle?
Axons of brain stem (i.e. vestibular nuclei) and spinal cord neurons, such as those from the dorsal spinocerebellar tract carrying proprioceptive feedback information
On which neuronal cell types do Purkinje cells of the cerebellar cortex form synaptic connections?
A. Thalamic neurons.
B. Dorsal root ganglion neurons.
C. Neurons within the frontal lobes of cerebral cortex.
D. Neurons within the deep cerebellar nuclei.
E. Granule cell neurons of the cerebellar cortex.
D) Neurons within the deep cerebellar nuclei
Do the dorsal root ganglion neurons have any synaptic connections on them?
No
The caudate nucleus receives a major input from what midbrain nucleus?
Substantia NIgra
What structure subdivides the cerebellum?
The vermis (aka spinocerebellum)
