L5 cerebellum Flashcards
superior peduncle
connects with midbrain
info going out of cerebellum
middle peduncle
connects with pons
info going into cerebellum
inferior peduncle
connects with medulla
info going into cerebellum
name the deep nuclei of cerebellum
dentate nucleus
emboliform nucleus
globose nucleus (interposed nucleus with top)
fastigial nucleus
what connects two cerebellar hemispheres?
vermis (worm)
role of deep cerebellar nuclei (2)
- receive both excitatory and inhibitory inputs from cerebellar cortex
- nuclei act as mini relay/control centres
state the specialised cells and axons of cerebellum (5)
granule cells purkinje fibres mossy fibres climbing fibres parallel fibres
roughly how many neurons in the cerebellum (1)
neurons in the cerebellum contain half of the entire brain’s neurons
state lobes of cerebellum
anterior lobe
posterior lobe
floculonodular lobe/ vestibulocerebellum
role of the cerebellum (2)
acts Subconsciously to ensure movement is smooth, coordinated, well-timed, spatially coherent, and matches motor plan
what pathway does the cerebellum sends its corrections through (direct or indirect)
indirect pathway
whats the input to output ratio of information towards cerebellum
40:1
where are the head and trunk located in the somatotopic map on the cerebral surface?
vermis
where are the limb representations located in the somatotopic maps on the cerebral surface?
either side of vermis on the intermediate regions
