Baseline connectivity differences between older African Americans and Caucasians with NC (p < 0.04). Among nodes distributed along the three subsystems, three node pairs’ connectivity differed between the races. In all instances, African Americans (green) with NC had lower connectivity between these node pairs than Caucasians (blue; bars represent mean values). TP = temporal pole, vlTC = ventrolateral temporal cortex, dmPFC = dorsomedial prefrontal cortex, dlTC = dorsolateral temporal cortex, TPJ = temporal parietal junction, pIPL = posterior inferior parietal lobule, pHG = parahippocampal gyrus, vmPFC = ventro-medial prefrontal cortex, PCC = posterior cingulate cortex
