How does the speed of a movement (e.g. reaching) affect its accuracy? Explain why. 10. Describe the effect on reaching movements of large-fiber sensory neuropathy (degeneration of the afferent fibers from the muscles and skin) when visual feedback is eliminated? Sketch the movements to illustrate your answer. 11. What are the primary brain areas involved in the control of movement? Give a brief description of their function. 12. What is the role of the posterior parietal cortex?...
