WebbFour principles are important to cerebellar processing: feedforward processing, divergence and convergence, modularity, and plasticity. Signal processing in the cerebellum is almost entirely feedforward. Signals move through the system from input to output with very little internal transmission. Webb11 sep. 2004 · • Rebound phenomena. This is also known as an impaired check, or an inability of muscles to adapt to rapid changes in load. For example, if the patient is …

WebbIt is concluded that the rebound phenomenon offers a rich and powerful mechanism for cerebellar nuclei neurons, which should allow them to differentially process the climbing fiber and mossy fiber inputs in a physiologically operating cerebellum. The output of the cerebellar cortex is controlled by two main inputs, (i.e., the climbing fiber and mossy … WebbNystagmus is defined by rhythmic, abnormal eye movements with a "slow" eye movement driving the eye off the target followed by a second movement that brings the eye back to the target.The movement can be horizontal, vertical, torsional or a combination of these movements. Nystagmus can be jerk (named for fast phase) or pendular, variable … marvin jones highlights

The actual cause of dysmetria is thought to be caused by lesions in the cerebellum or by lesions in the proprioceptive nerves that lead to the cerebellum that coordinate visual, spatial and other sensory information with motor control. Damage to the proprioceptive nerves does not allow the cerebellum to accurately judge where the hand, arm, leg, or eye should move. These lesions are often caused by strokes, multiple sclerosis (MS), amyotrophic lateral sclerosis (ALS), or tumors. http://syllabus.cwru.edu/YearThree/neuroscience/NeurLrngObjectives/Cerebellar.htm WebbDysdiado chokinesia (the inability to perform rapidly alternating movements) , intention tremor, and rebound phenomenon (loss of interaction between agonist and antagonist smooth muscles) are also typical.
