German physiologist Ewald Hering in 1861. The Hering illusion is a geometrical-optical illusions, discovered by Particularly the parietal lobe, because it is involved in perceiving movement. Spontaneous fluctuations in cortical activity while watching this illusion, Recent studies show on the fMRI that there are The dancer appears to be rotatingĬlockwise or counterclockwise, depending on spontaneous activity in the brain The ambiguity of direction of motion due to lack of visual referencesįor depth is shown in the spinning dancer illusion. Like a truck, although the larger object is actually moving faster. Large object, like a jet fighter, to move more slowly than smaller objects, We are moving, stable surrounding objects may appear to move. Slightly varied images produced in rapid succession as a moving picture. Animation is based on the illusion that our brains see a series of Perception, motion perception can be responsible for several sensory Of depth, proximity and our understanding of the physical world to create an In the Ponzo illusion the converging parallel lines tricks the brain into thinking that the image higher in the visual field is farther away, so the brain thinks the image is larger, but the two images hitting the retina are same in size. the [vertical-horizontal illusion ( ) where the two lines are exactly the same in length. Tough even with two dimensional images, the brain over compensates vertical distances when compared with horizontal distances, e.g. Illusion is an example in which it uses monocular cues of depth perception to trick the eye. ![]() Three dimensions even though the image hitting the retina is just two dimensional. Illusions can be based on someone’s ability to see in
