1

Coordination of voluntary movements

Posterior lobe

2

Maintain coordination of limb movements while the movements are being executed

Regulation of muscle tone

Anterior lobe

3

Responsible for coordination of the paraxial muscles associated with equilibrium

Flocculonodular lobe

4

ATAXIA (loss of coordination of voluntary movements)

Rate, range and force of movements are abnormal resulting to intention tremor

DYSMETRIA - overshoots or undershoots when attempting to touch a target

DYSDIADOCHOKINESIA - inability to perform rapid alternating movements

POSTERIOR LOBE SYNDROME

5

Loss of coordination chiefly in the lower limbs

Marked gait instability

Sliding the heel of one foot smoothly down the shin of the other leg is extremely difficult for the patient to do

ANTERIOR LOBE SYNDROME

6

Truncal ataxia

FLOCCULONODULAR LOBE SYNDROME

7

Anatomical subdivisions

ANTERIOR LOBE: Paleocerebellum / Spinocerebellum (limbs via spinal connections)

POSTERIOR LOBE: Neocerebellum or Cerebrocerebellum (cerebral cortex)

FLOCULONODULAR LOBE: Archicerebellum or Vestibulocerebellum (vestibular apparatus)
