Analysis stages. (A) Each stage shown in a row, with analyses to the right performed on residuals from that stage. (B) Sources of variance in the residuals of current stage. (C) Mean evoked responses across blocks, with proportions of variance explained by average block response. (D) V4-FFA/PPA correlations. Despite the large reduction in the variance explained by evoked responses across analysis stages, there are negligible changes in the attentional modulation of V4 connectivity (main effect of reduced correlations, but no change in the ROI × state interaction; see text). This suggests that attentional modulation of connectivity does not depend on stimulus responses but rather on spontaneous activity commonly used to measure intrinsic brain networks at rest.
