CFF increased linearly with luminance but reached an asymptote above 3.0 log trolands. Deuteranopes showed a higher asymptotic CFF than protanopes for all field sizes. The relative spectral sensitiv

A blue (440 nm) reversing checkerboard pattern of 6 deg (40′ checks) was presented on a steady, yellow (575 nm), 15 deg adapting background of various luminance levels ranging over 6.5 log units. The luminance level used to evoke VEPs was set 1 log unit above the psychophysical incre

Conversely, VEPs generated by gratings modulated in hue along R-G or B-Y axes of the chromatic plane are qualitatively different from those derived from the luminance axis: grating onset elicits VEPs dominated by a . wave, different fro
