Document Summary
Motion is really just a change in an object"s location over time . Fast detection of direction of motion is important to our survival. Motion aftereffect (mae) the illusion of motion of a stationary object that occurs after prolonged exposure to a moving object. After observing motion in a constant direction for at least 15 seconds, we see any stationary objects as moving in the opposite direction. Caused by opponent processes for motion detection. Start: with 2 adjacent receptors separated by a fixed distance (a and b). An object moving from left to right would first pass through neuron a"s rf and then enter neuron b"s rf. Apparent motion illusory impression of smooth motion resulting from the rapid alternation of objects that appear in different locations in rapid succession. Neural circuit does not need continuous motion in order to fire! It just has to look like continuous motion.
