Figure 2. Seed derivation for the connectivity analyses. Task-specific seeds for functional and effective connectivity during tasks were derived by overlapping activation maps from either the N-back or RP task, and the DMN and PCu masks from the Conn atlas. Analysis for each task was carried out independently. For task-independent structural and resting-state functional connectivity, the PCu seeds (d/vPCu) were defined as the spatial intersection of the activated or deactivated clusters in both tasks, the DMN and the PCu masks.
