5. Motion perception is an important aspect of daily visual experience. (a) Describe the circuit for the Reichardt detector. What are the components? Is the circuit direction-sensitive and speed-sensitive? Explain why. - - (b) Medial temporal (MT) area has been found to play a crucial role in motion perception. List three physiological evidences that support the causal role of MT in motion perception. M (c) Can we rely on shifts in the retinal image to infer whether there is object motion? If so, how do we directly relate shifts in the retinal image to the speed and the direction of object motion? If not, list counter-examples and explain other factor(s) the visual system takes into account when inferring whether there is object motion? - (d) Explain colollary discharge theory, and based on this theory, what's the computation under the hood for the speed and direction of object motion.
