Social modulation of network functional connectivity. A, Average connectivity matrices calculated from scenes during which monkeys viewed multiple macaques engaged in each of the three social interactions of interest (aggressive, affiliative, and ambiguous behavior). B, Results of a repeated-measures ANOVA assessing the degree to which network functional connectivity was modulated by social interaction (within-subject factor with three levels, aggressive/affiliative/ambiguous; for details, see Materials and Methods). The z statistic and p values obtained from this analysis for each connection are displayed as summary matrices. Connections with the strongest social modulation were selected with a threshold of z > 2.05 (equivalent to the strongest 15% of connections, suprathreshold connections outlined in black). C, Suprathreshold connections are graphically represented in blue between ROIs in the network (left). Simplified graphical representation of connections between the left and right frontal and temporal lobes. The thickness of the connecting line represents the proportion of suprathreshold connections displaying social modulation of functional connectivity.
