ROIs sensitive to both PM and WM load in a transient fashion
—

Note: No ROIs were identified as sensitive to PM task demands in a transient, ongoing fashion. Statistics in the last 6 columns reflect t-statistics for each direct comparison. Parentheses next to a region name indicate a label for an illustrated ROI in Figures 3 and 4. Abbreviations: L = left; R = right; Ant = anterior; Inf = Inferior; Lat. = lateral; Post = posterior; ACC = anterior cingulate cortex; PFC = prefrontal cortex. ***P < 0.001, **P < 0.01, *P < 0.05.
