Below is one example of a visual illusion of motion that I made. In class I showed you a number of demonstrations in which motion is misperceived. Motion is a perceptual attribute: the visual system infers motion from the changing pattern of light in the retinal image. Corrolary discharge explains why eye movements do not evoke a perception of motion.STS is specialized for recognizing biological motion.Cortical area MST is functionally speicalized for optic flow.Well-defined pathway of brain areas (cascade of neural computations) underlying motion specialization in MT.Computational theory quantitatively explains both the responses of MT neurons and the perception of visual motion.Electrical stimulation in MT causes changes in visual motion perception.Damage to MT or temporary inactivation causes deficits in visual motion perception. ![]()
