While various expertise domains have been studied extensively, the literature body provides only a few reports on chess expertise at rest. To fill the literature gap of resting-state study on chess expertise, we fALFF differences on a dataset consists of 29 chess experts and 29 novices and found a higher fALFF in the right insula cortex (IC,r). A further seed-to-voxel functional connectivity analysis seeding IC,r reveals a higher functional integration with two regions involves in object recognition, suggesting its role in integrating visual processing in salience network among chess experts.
