“…Pattern adaptation in V1 is most likely responsible for a variety of after-effects that can influence the perception of stimulus size or orientation (Blakemore and Campbell, 1968;Gilinsky, 1968;Pantle and Sekuler, 1968), or other stimulus attributes (see review in Graham, 1989). A classical demonstration of an after-effect in the orientation domain is illustrated in Fig.…”

“…Some of the properties of channels have been inferred from adaptation studies (Gelinski, 1968;Pantle and Sekuler, 1968;Blakemore and Campbell, 1969) and from studies of masking with one-dimensional noise (Greis and Roehler, 1970;Stromeyer and Julesz, 1972;Henning er al., 1981;Henning, 1988). Channels have been compared with simple cells in mammalian visual cortex which also behave as if they were summing devices sensitive to limited ranges of orientation and spatial frequency (Maffei and Fiorentini, 1973;De Valois et al, 1982).…”

Ahatraet-Gratings that differ in orientation by as much as 62.5 deg from that of a signal grating raise the signal's threshold by nearly a log unit. The spatial-frequency tuning of the masking effect reaches a maximum slightly below the spatial frequency of the maskers but far from that of any quadratic distortion product. Further, the location of the peak does not depend much on the relative orientation of the signal and maskers thus making it unlikely that the masking effect can be explained in any simple way by the presence of visual nonlinearities. This illustrates the difficulty of attempting to explain human performance in even relatively simple discrimination experiments with models based on mechanisms tuned for spatial frequency and orientation.

“…Prolonged viewing of a grating increases the threshold for detecting patterns with similar orientation (Gilinsky, 1968) and spatial frequency (Pantle and Sekuler, 1968;Blakemore and Campbell, 1969). Blakemore and Campbell observed that a sinusoidal adapting grating maximally elevates the threshold of a grating at the same spatial frequency but has little effect on gratings one octave from the adapting frequency.…”
