Neural dynamics and brain function

A sinusoidal grating appears of higher spatial frequency when briefly flashed than when presented for longer durations. This effect is restricted to gratings of low spatial frequency (1 cycle/deg). Time-dependent changes in the response of spatial frequency channels are a likely cause.
