Relationship of saccadic suppression to space constancy - Response

Saccadic suppression is selective, inhibiting only low spatial frequencies. High spatial frequencies need not be inhibited during saccades, for a rapidly moving retina lacks the temporal resolution to detect them. Low spatial frequencies are inhibited by suppressing magnocellular channels. Thus color information is not suppressed, as confirmed in two laboratories. Targets flashed during and just before saccades can be mislocalized because vision normally ignores presaccadic position information.
