Cerebellar
Unlike other brain regions, the cerebellum does not send signals directly to alpha motor neurons. Instead, it acts as this to refine movement.
What is a comparator?
This term describes a breakdown of multi-joint movements into individual joint actions and is considered a compensatory strategy.
What is decomposition?
The standardized clinical scale for assessment and rating of ataxia.
What is SARA?
This degenerative, autosomal dominant disorder is usually diagnosed in adulthood and involves cerebellar and/or extracerebellar structures.
What is spinocerebellar ataxia (SCA)
If these structures are intact after a cerebellar stroke, then it is the best predictor for recovery.
What are deep cerebellar nuclei?
This intervention once thought to improve cerebellar tremor may actually worsen multi-joint movement errors due to increased inertia.
What is weighting?
Clinical signs of damage are dysdiadochokinesia, dysmetria, dyssynergia, and decomposition.
What is damage to the cerebrocerebellum?
The two functional zones of the cerebellum that are responsible for gaze, eye movements and balance. Be specific.
The compensatory strategy to help reduce dyssynergia and dysmetria.
What is reducing the number of segments moving at the same time?
Cerebellum-dependent motor learning is driven by this specific type of error, rather than target error or knowledge of results.
What is sensory prediction error?
