Last two columns give linear correlation coefficients (r) and p values for correlations across subjects between acuity threshold and β weight of activation for each ROI on the spatial task relative to baseline. Values in bold indicate significant correlations (p < 0.05). L, Left; R, right; IFS, inferior frontal sulcus; mIPS, mid-intraparietal sulcus; VPL, ventral posterolateral; MD, mediodorsal; MFG, middle frontal gyrus.
