Statistics: *P<0.05 and **P<0.01; t-values for reaction time (generalized linear mixed models) or Z-scores for accuracy (logistic regressions). DLPFC: dorsolateral prefrontal cortex; mPFC: medial prefrontal cortex; PCC: posterior cingulate cortex; ROI: region of interest; SE: standard error; tDCS: transcranial direct current stimulation; iTBS: intermittent theta-burst stimulation.
