Visual Stability and the Motion Aftereffect: A Psychophysical Study Revealing Spatial Updating
Eye movements create an ever-changing image of the world on the retina. In
particular, frequent saccades call for a compensatory mechanism to transform the
changing visual information into a stable percept. To this end, the brain
presumably uses internal copies of motor commands. Electrophysiological
recordings of visual neurons in the primate lateral intraparietal cortex, the
frontal eye fields, and the superior colliculus suggest that the receptive
fields (RFs) of special neurons shift towards their post-saccadic positions
before the onset of a saccade. However, the perceptual consequences of these
shifts remain controversial. We wanted to test in humans whether a remapping of
motion adaptation occurs in visual perception
