Extended Data Fig. 7. Characterisation of synergistic and redundant network profiles in macaque brains are similar to humans.

Extended Data Fig. 7

(a) Synergistic interactions between regions of the macaque brain. (b) Redundant interactions between regions of the macaque brain. (c) Anatomical connectivity was estimated from axonal tracing and diffusion MRI (Shen et al., 2019), and Spearman correlation coefficient was used to assess the similarity of redundancy and synergy matrices with structural connectivity, after thresholding to ensure equal numbers of connections. (d) The network organisation of synergistic interactions exhibits significantly higher global efficiency than redundant interactions (p < 0.001). (e) The network organisation of redundant interactions exhibits significantly higher segregation (modularity) than synergistic interactions(p < 0.001). (f) Networks of redundant interactions are significantly more correlated with underlying anatomical connectivity than synergistic interactions (p < 0.001). For all tests: *** p < 0.001 from paired-sample non-parametric permutation t-test (two-sided); n=19 distinct sessions from 10 individual macaques (Supplementary Table 7). For all violin plots: each colored circle indicates one data-point; white circle: median; central line: mean; box limits, upper and lower quartiles; whiskers, 1.5x inter-quartile range.
