Summary Functional Organization of the Cerebellum

Functional Organization
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
