Connectivity matrix for a representative subject showing z-scores between all pairs of ROIs. Each entry displays the z-score of one pair of ROIs, with the x and y axes corresponding to the ROI indices (1-40). In the caffeine session, the z-scores in the post-dose session are visibly lower than those in the pre-dose section. In the control session, the z-scores are comparable in both the pre-dose and post-dose sections. ROI labels (1-20 left hemisphere; 21-40 right hemisphere): anterior cingulate, middle frontal, cuneus, fusiform, inferior parietal, isthmus cingulate, lateral orbitofrontal, medial orbitofrontal, pars opercularis, post central, posterior cingulate, precentral, precuneus, rostral anterior cingulate, rostral middle frontal, superior frontal, superior parietal, superior temporal, supramarginal, insula.
