Ongoing neural activity associated with the cognitive set. (A and B) Spatial distribution of cortical regions showing trial-by-trial correlation between baseline neural activity and task performance. Baseline γ-band (55–85 Hz) power in the TL accounted for variation in planning time of Communicators and Addressees; baseline γ-band power in the parietooccipital cortex (POC) accounted for variation in planning time of Salesmen and Roadworkers. (C) Group-averaged correlations for each of the two tasks and cortical regions (±1 SEM).
