AB  - Cognitive performance relies on the coordination of large-scale networks of brain 
      regions that are not only temporally correlated during different tasks, but also 
      networks that show highly correlated spontaneous activity during a task-free 
      state. Both task-related and task-free network activity has been associated with 
      individual differences in cognitive performance. Therefore, we aimed to examine 
      the influence of cognitive expertise on four networks associated with cognitive 
      task performance: the default mode network (DMN) and three other cognitive 
      networks (central-executive network, dorsal attention network, and salience 
      network). During fMRI scanning, fifteen grandmaster and master level Chinese 
      chess players (GM/M) and fifteen novice players carried out a Chinese chess task 
      and a task-free resting state. Modulations of network activity during task were 
      assessed, as well as resting-state functional connectivity of those networks. 
      Relative to novices, GM/Ms showed a broader task-induced deactivation of DMN in 
      the chess problem-solving task, and intrinsic functional connectivity of DMN was 
      increased with a connectivity pattern associated with the caudate nucleus in 
      GM/Ms. The three other cognitive networks did not exhibit any difference in 
      task-evoked activation or intrinsic functional connectivity between the two 
      groups. These findings demonstrate the effect of long-term learning and practice 
      in cognitive expertise on large-scale brain networks, suggesting the important 
      role of DMN deactivation in expert performance and enhanced functional 
      integration of spontaneous activity within widely distributed DMN-caudate 
      circuitry, which might better support high-level cognitive control of behavior.
