Fig. 2: Matrix representation of the five fMRI connectivity groups that account for 97% of the connectivity in SZ and BP patients.

Number of connections and their relative importance are shown and color coded [blue indicates positive connections (correlation greater than in controls) whereas red shows negative connections (correlation less than in controls)]. The number in the cells represents edges (i.e., links) are the functional connections between nodes (i.e., component brain regions or fMRI networks) that specify the connectivity networks (see also Figures S2 and S9). A–E represent each of the five sets that describe different patterns of connections among the nodes: A the Avoidant-Anhedonic (group 1), B the Sensitive-Disorganized subjects (group 2), C the Asocial-Blocked subjects (group 3), D the Fragile-Avolitional subjects (group 4), and E the Explosive-Inattentive individuals (group 5).
