RT Journal Article T1 Efficiency at rest: Magnetoencephalographic resting-state connectivity and individual differences in verbal working memory A1 Del Río Grande, David Pedro A1 Cuesta Prieto, Pablo A1 Bajo Bretón, Ricardo A1 Pacios García, Javier A1 López Sánchez, Ramón A1 Pozo, Francisco del A1 Maestu Unturbe, Fernando AB Inter-individual differences in cognitive performance are based on an efficient use of task-related brain resources. However, little is known yet on how these differences might be reflected on resting-state brain networks. Here we used Magnetoencephalography resting-state recordings to assess the relationship between a behavioral measurement of verbal working memory and functional connectivity as measured through Mutual Information. We studied theta (4–8 Hz), low alpha (8–10 Hz), high alpha (10–13 Hz), low beta (13–18 Hz) and high beta (18–30 Hz) frequency bands. A higher verbal working memory capacity was associated with a lower mutual information in the low alpha band, prominently among right-anterior and left-lateral sensors. The results suggest that an efficient brain organization in the domain of verbal working memory might be related to a lower resting-state functional connectivity across large-scale brain networks possibly involving right prefrontal and left perisylvian areas.
