Task fitness and pretraining FC to/from visual cortex. (A) Voxel-wise FC–PC1 correlation map starting from a seed region in the right ventral visual seed (V1–V2; black border), corresponding to the left upper visual quadrant. The map is projected onto a flattened representation of the posterior occipital cortex using the PALS atlas (29). Color scale: yellow/orange indicates positive correlation (Z-statistic of Pearson r) thresholded at Z > 2, P < 0.05, and Monte Carlo corrected. Blue color indicates negative correlation. Blue lines are the same as in Fig. 1D. L.H., left hemisphere; R.H., right hemisphere. (B) x axis, task fitness, i.e., principal component scores of PC1; y axis, FC (Fisher Z-transformed) between a right ventral visual seed V1–V2 (green, Inset; same as in A) and a left dorsal visual region (red) extracted from the FC–PC1 correlation map in A (Talairach coordinates, −06 −96 +08; 185 voxels). Each diamond represents an observer. (C) Conjunction of eight voxel-wise FC–PC1 correlation maps, one for each visual seed shown in Fig. 1D (Table S1 provides coordinates). Color scale: yellow/orange indicates overlap of positive correlations (range, 1–8); cyan/blue indicates overlap of negative correlations. (D) Conjunction map between visuotopic localizer activations (Z statistic > 3, P < 0.05, Monte Carlo corrected; Methods; red) and FC-PC1 conjunction map thresholded four of eight (green). Overlapped voxels are in yellow.
