Cerebellum Flashcards
Neuron in cerebellar cortex with a flat dendritic tree
Purkinje cell
Cerebrum means
Little brain
Left cerebellum controls
Left side of body
Left cerebral cortex
Right cerebellum
Dysdiadochokinesia is
Inability to coordinate rapidly alternating movements
2 sources that provide input to cerebellar cortex
Mossy fibers and climbing fibers
Cerebellum plays a key role in computations for what function
Working memory, language, movement coordination
Cerebellum communicates with he rest of CNS through what
Cerebellar peduncles
Fractured somatotopy in the cerebellum refers to what
Multiple, discontinuous, body representations
Vestibulocerebellum is important for what
Balance, posture, eye movements
Cerebrocerebellum
Planning, timing, coordination of complex movements
Spinocerebellum
Intermediate zone - control proximal and into distal muscles
Vermis - control axial and trunk muscles
Lesion to spinocerebellum (vermis)
Falls to ipsilateral side
Lesion to spinocerebellum (intermediate zone)
Ipsilateral action tremor with voluntary movements
Lesion to cerebrocerebellum
Dysmetria = inability to control speed, distance, and range in motion
Ataxia = lack of coordination and balance
