Structural connections between the caudate subdivisions and the ACC. (A) Anterior and posterior caudate subdivisions together with the white matter tracts connecting them to the ACC, defined using the HCP data. (B) Differences in caudate-ACC white matter integrity between patients with TBI and healthy controls (CON). (C) Graphs representing correlations between fractional anisotropy measures in two white matter tracts and performance on the Stroop task executive function measure corrected for baseline speed. Reductions in white matter integrity were correlated with slower reaction times. Spearman’s partial correlations were significant at P < 0.05, FDR corrected for multiple comparisons. Fractional anisotropy measures have been plotted with variance for age partialled out.
