Figure 6. Results of a voxel-wise correlation between global imaginary coherence (GC) at rest in the AgCC cohort (scatterplots, in black) and verbal processing speed (VPS) performance on the D-KEFS Color-Word Interference Test.

Functional connections of two regions in the left hemisphere were positively correlated (overlay, in red) with processing speed in AgCC, in the left medial temporal gyrus (MTG) and the superior temporal gyrus (STG). These same two regions were not found to be significantly correlated with processing speed in healthy controls (scatterplots, in red). No regions in the right hemisphere were correlated with verbal processing speed in any group. pAgCC  =  partial agenesis of the corpus callosum. cAgCC  =  complete agenesis of the corpus callosum. Statistical maps (Pearson's r) are thresholded (p<0.05, 1% FDR correction) and superimposed as in previous figures.
