“…(through saturation) [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22], when using simultaneous brightness match but not when using flicker technique, has found its solution in the so-called minimally distinct border (MDB) technique [15] . This is fairly strongly supported by recent electrophysiological evidence on the separation of brightness and colour processing [27][28][29][30][31][32] . Terms like opponent and non-opponent mechanisms, and tonic and phasic cells are nowadays currently employed in the literature on vision .…”

“…Or is it within the achromatic or luminance pathway sensitive to higher spatial frequencies and linked to the parvocellular stream of processing, which also encodes chromatic information? The dual nature of the luminance pathway has been discussed in several papers by Ingling et al (Ingling & Drum, 1973;Ingling & Martinez-Uriegas, 1983, 1985Ingling & Tsou, 1988) and has also been covered in several reviews (e.g., Lennie, Pokorny, & Smith, 1993;Stockman & Brainard, 2009).…”

Flickering 560-nm light appears brighter and less saturated than steady light of the same average intensity. The changes in appearance are consistent with the visual signal's being distorted at some nonlinear site (or sites) within the visual pathway at which new temporal components, not part of the original waveform, are produced. By varying the input stimulus to manipulate these new temporal components--called distortion products--and measuring our observers' sensitivity in detecting them, we derived the temporal attenuation characteristics of the early (prenonlinearity) and late (post-nonlinearity) stages of the L- and M-cone pathway that signals brightness. We found that the early stage acts like a band-pass filter peaking at 10-15 Hz with sensitivity losses at both lower and higher frequencies, whereas the late stage acts like a two-stage low-pass filter with a corner frequency near 3 Hz. Although brightness is often associated with the fast achromatic or luminance pathway, these filter characteristics, and particularly those of the late filter, are consistent with comparable features of the L-M chromatic pathway that produce mainly chromatic distortion products (Petrova, Henning, & Stockman, 2013). A plausible site for the nonlinearity is after surround antagonism from horizontal cells. Modeling suggested the form of the nonlinearity to be initially expansive but possibly with a hard limit at the highest input levels.

“…Secondly, it has been described how cone-opponent pathways in general are able to perform a 'double duty' since their response is governed by both the luminance and the colour contrast in a stimulus (Ingling & Drum, 1973;Ingling & Martinez, 1983). Thus, any arrangement of the short wavelength chromatic mechanisms into spectrally and spatially opponent pathways is likely to provide both a cone-additive (non-opponent) and a cone-subtractive (opponent) component to their response.…”

SUMMARY1. Spatial and temporal contrast sensitivities were investigated in two subjects whose photopic vision has been previously shown to be subserved by only short wavelength cones.2. Spatial contrast sensitivity was uniformly reduced compared with that of the normal trichromatic observer. Peak contrast sensitivity reached 40 which is a factor of 2-3 better than previous estimates and extrapolated acuity was around 15 cycles deg-'. Central, non-aliased grating acuity was between 6-9 cycles deg-'. This declined with eccentricity such that at 20 deg it was around 1 cycle deg-'.3. The variation in contrast sensitivity across the visual field was measured for a range of different spatial frequencies. It was found to be of the same form as that for the normal trichromat but reduced in overall sensitivity.4. Temporal contrast sensitivity was measured for two different spatial frequencies and found to exhibit the spatio-temporal covariation which is typical of normal trichromatic vision. Temporal acuity exhibited a strong dependence on illuminance and reached asymptotic values of around [40][41][42][43][44][45] While this is more than a factor of two above most previous estimates for the short wavelength receptors of normal vision it agrees with some more recent estimates obtained using a different technique. Temporal resolution was found to be evenly distributed across the visual field.5. Similarities were found between the post-receptoral properties of these achromats and the properties of the isolated blue mechanism of normal vision and also the properties of normal luminance contrast processing in general. The present results provide an upper bound on the contribution of the short wavelength mechanism to normal vision and also provide a suitable model of its possible contribution to the processing of luminance contrast in the normal visual system.
