Document Summary
Many cells in v1 selectively respond to motion in one particular direction. Motion aftereffect (mae) = illusion of motion of a stationary object that occurs after prolonged exposure to a moving object. Similar to color aftereffect, just as it is caused by opponent processes for color vision. Mae is caused by opponent processes for motion detection. If fixate on falling object then watch stationary object that object seems to be moving up. To build a motion detector start with 2 adjacent receptors pt a and b, neuron a and b, separated by a fixed distance. A bug moving from left to right would first pass through neuron a"s receptive field then a short time later would enter receptor b"s receptive field. Thus a 3rd cell (m-motion detection cell) that listens to neurons a and b should be able to detect this movement.
