Figure 7. Results of a voxel-wise correlation between global imaginary coherence (GC) at rest in the AgCC cohort (in black) and problem solving (PS) performance on the D-KEFS Tower Test.

Functional connectivity of a region in medial pre-frontal cortex (PFC, top panel) and the left superior frontal gyrus in Brodmann's Area 8 (BA8; bottom panel) was positively correlated with Tower scores (p<0.05, 5% FDR correction) in the AgCC group. No significant relationship between performance on Tower and functional connectivity was identified in the healthy control group (in red). Conventions as in Figure 4. Statistical maps (Pearson's r) are thresholded (p<0.05, 10% FDR correction) and superimposed as in previous figures.
