Sus-tentorial laterality index (LI) of the resting-state language network (LANG) identified by spatial independent components analysis and of the contrast sentence generation > tones-listening for the covert and overt sessions (Covert and Overt contrasts). Sus-tentorial LI for the explicit tasks were calculated using pre- and postcentral gyri as the exclusive mask. A The LI shift from the resting-state to the covert session (n = 32). B The LI shift from the covert to the overt session (n = 33). C One-way analysis of variance (n = 32). Positive LI indicates left lateralization
