Fig. 5.
Laminar profiles of differential responses to chromatic vs achromatic stimuli in V1 as a function of eccentricity. (A) Differences were normalized by the average of both responses to eliminate dependence on overall BOLD response amplitude as a function of depth or eccentricity. Profiles were computed separately for parafoveal, middle, and peripheral ROIs. The shaded area around each profile is the standard error (n = 10). (B) Individual subject signal change is displayed as single points for the most superficial layer and the deepest layer. Significant differences are discussed in main text.
