Cerebellum Lecture - Neuropsych
Flashcards do conjunto (12)
- 1What are the functions of the cerebellum?1. Help to stabilize posture, balance, and gait
2. Timing and coordination of eye movements
3. Timing and coordination of limb movements
4. Motor learning based on error feedback
5. Cognitive functions (ie. attention, working memory) - 2What is the anterior lobe in the cerebellum responsible for?Balance, posture, gait
- 3What is the posterior lobe of the cerebellum responsible for?Coordination of limbs and motor learning
- 4What are the three cerebellar output nuclei?Fastigial, interposed (globose & emboliform), and dentate
- 5What are the three major arteries that supply blood to the cerebellum?1. Superior cerebellar artery (SCA)
2. Posterior-inferior cerebellar artery (PICA)
3. Anterior-inferior cerebellar artery (AICA) - 6What are the three cerebellar peduncles?1. Superior (SCP)
2. Middle (MCP)
3. Inferior (ICP) - 7Where does the cerebellum receive inputs from?The pons, with the MCP acting as a funnel; and the brainstem & spinal cord
- 8Where does the cerebellum output to?The red nucleus (rubrospinal tract); VA + VL; medial dorsal nuclei of thalamus (SCP)
- 9What cell(s) input to the cerebellum, and what cell(s) output to the deep cerebellar nuclei?Input: Mossy fibers & climbing fibers
Output: Purkinje cells - 10Where does the fastigial and interposted cerebellar nuclei output to?Fastigial: Reticular formation & vestibular nuclei
Interposed: Motor cortex (via VA+VL thalamus) and brainstem (via inferior olive) - 11What are the four common symptoms of cerebellar damage?Dysdiadochokinesia; intention tremor; abnormal gait, postural instability; movement dysmetria
