From: fMRI measurements of color in macaque and human
Journal of Vision. 2008;8(10):6. doi:10.1167/8.10.6
Figure Legend:
Diagrams of stimuli used in the macaque and human versions of our experiments. (a) Full field alternation of a blank
field with textured chromatic or achromatic contrast. (b) Adding contrast in one dimension to constant dynamic contrast in
another dimension. Upper versus lower visual field. (c) Adding contrast in one dimension to constant contrast in another
dimension. Full field alternation. Arrays subtend 12 degrees of visual angle and contain 12 × 12 square patches.
Contrast patterns in the addition experiments (b, c) are updated at 1 Hz with a new random draw from the same color
space. The contrast versus blank condition (a) was run at update rates of either 1 or 7 Hz.
