A) Average IRCs across bilateral language-responsive areas in the inferior frontal cortex, temporal cortex, and angular gyrus during story comprehension and rest (averaging across these 2 naturalistic conditions), which were computed using publicly available data from Malik-Moraleda et al. (2022). The LH fronto-temporal language regions are strongly inter-correlated. The RH fronto-temporal language areas and language areas in the bilateral angular gyri are also internally correlated, although to a lesser extent than the LH language areas. B) Average (off-diagonal) IRCs within (first 3 bars) and between (last 3 bars) sets of language areas (i.e. LH language areas [LH], RH language homotopes [RH], and language areas in the angular gyri [AG]). Error bars show standard errors of the mean across participants and region-region pairs. Horizontal bars show significant differences between average IRCs by permutation test (all P < 0.0001). All within- and between-set average IRCs are significantly >0 by bootstrap test (all P < 0.0001), but critically, the correlations within each of these 3 sets are higher than they are between them.
