Document Summary
Number of the neurons in the cerebellum: contains half of the neurons in the brain, but only 10% of the total volume of the brain. Complete cerebellum removal: no muscle weakness (or no paralysis) not like m1 damage (paralysis, no loss of perception. No direct connections with mns (motor neurons) Regulates movement & posture indirectly : by adjusting output of major descending motor systems. Input from : somatosensory & proprioception. Timing device: correct order & timing. Lesion no smooth timing / movement. Coordination: assemble / coordinate of complex multi-joint or multi-limb movements, lesion disrupts . Permanent cerebellum damage is similar to chronic alcohol consumptions. Comparator: coach of the motor system, motor plan & actual motor execution are different. Unconscious process do not recognizes the differences. Parallel system adjustment: compensates for movement errors by , comparing sensory feedback with intention of motor plan (c. f. Motor plan = efference copy = corollary discharge)
