Document Summary
Shape, location in space, color her fundamental perceptual dimensions. Motion as a low-level perceptual phenomenon cells in primary visual cortex selectively respond to motion in one particular direction. The illusion of motion of a stationary object that occurs after prolonged exposure to moving objects. Just as color after effects are caused by opponent processes for color vision, the motion after effect is caused by opponent processes for motion detection. Promotion detector is velocity sensitive in their direction sensitive. One possible objection to this neuronal circuit is that it does not, in fact, require continuous motion in order to fire. The reeichardt model provides an excellent explanations were visual illusions that modern humans experience on a daily basis. Apparent motion that illusory impression of smooth motion resulting from the rapid alternation of objects that appear in different locations and rapid succession. first demonstrated by sigmund exner in 1875.
