Flashcards in W03_05 Motor Control 3: Cerebellum Deck (13)
what volume proportion of the brain does the cerebellum hold?
what proportion of neurons does the cerebellum hold?
what is the general function of the cerebellum?
refines movements and makes them better. takes input from motor planning and modifies according to sensory input. does not alter strength or sensory perception.
name 4 general functions that the cerebellum assists
spinocerebellum consists of which two parts?
vermis and paravermis
function of the spinocerebellum?
descending motor systems (i.e. proprioception, stance, posture)
function of the cerebrocerebellum?
to motor/premotor cortex;
fine movement of hand
function of the vestibulocerebellum?
to vestibular nuclei;
neurons of proprioceptors follow which tract up the spinal cord?
where do outputs from the vestibuloCB and spinoCB project to?
ipsilateral extraocular nuclei for coordinating eyes with head mvmt;
ipsilateral reticulospinal and vestibulospinal tracts for coordinating balance and locomotion
pathway of cerebrocerebellum output?
dentate nucleus (cerebrocerebellum);
sup cereb ped.;
VL thalamus synapse;
name classic symptoms of cerebellar disease
