Figure 4. Synchronization differences.
(a) Matrix of significant differences of synchronization between AD and controls (2-tail t-test, p<0.05 uncorrected). The white and black dots represent brain areas pairs with increased and decreased synchronization in AD respectively. (b-d) A subset of connectional differences corresponding to the matrix (a) are plotted at 3 superior-to-inferior levels through the AAL brain template: (b) = z53; (c) = z73; (d) = z111. Lines depict synchronization between pairs of regions: solid lines = enhanced synchronization; dashed lines = reduced synchronization. Note the pattern of generalized posterior (parietal and occipital) synchronization reductions and increased frontal synchronization.
