Abstract

The effects of temporal modulation on human sensitivity to gratings of low spatial frequency cannot be explained by a change in the spatial frequency tuning characteristics of single neurones, unless neurones in the visual cortex of man are different from those in cat. Although the authors did not observe much variation among the temporal characteristics of striate neurones, it has been reported elsewhere that visual cortical neurones can be subdivided into a sustained group sensitive to high spatial frequencies and a transient group more sensitive to lower frequencies, which may represent the two populations of neurones required to explain the increase in low frequency sensitivity produced by temporal modulation seen psychophysically.
