Task-related changes in degree centrality and local coherence of the posterior cingulate cortex after major cardiac surgery in older adults

Older adults often display postoperative cognitive decline (POCD) after surgery, yet it is unclear to what extent functional connectivity (FC) alterations may underlie these deficits. We examined for postoperative voxel-wise FC changes in response to increased working memory load demands in cardiac...
