Cerebral cortex

1. Name one of the primary areas of the neocortex that is likely to have a thick cortical layer IV and explain why this is so. 2. Which area of the body would be most affected by a large lesion of the primary motor cortex? Why? Would it be contralateral or ipsilateral? (Hint: Also think about what body regions have a lot of neurons to control their movement and sensation.) 3. Which visual processing stream is involved in affordance? Why? 4. Describe 2 pathways by which the cerebellum controls movement 5. Name and describe the difference between the two afferent fibers in the cerebellum. Which one encodes information about the error signal between expected and actual sensory feedback? 6. Which part of the basal ganglia produces and supplies dopamine to the striatum? What two pathways does dopamine facilitate?
