of the Cerebellum
Objectives
review anatomy
functions of the cerebellum
afferent and efferent pathways
cerebellum dysfunction
MOTOR HIERARCHY
Cerebellar motor functions
Functional Organization of the Cerebellum 1
, implemented via the lateral and medial pathways, ESPECIALLY
the corticospinal tracts
incorporated into motor programs via frontal areas. the
motor programs originate from the primary motor area,
premotor area and supplementary motor area
Deep cerebellar nuclei
dentate nuclei → to frontal motor areas. the dentate nuclei
sends efferent fibers to the proximal 1/3 of the red
nucleus and to the ventrolateral nucleus of the thalamus
