Transcranial DC stimulation modifies functional connectivity of large‐scale brain networks in abstinent methamphetamine users

摘要

BackgroundTranscranial direct current stimulation (tDCS) is a noninvasive brain stimulation tool suited to alter cortical excitability and activity via the application of weak direct electrical currents. An increasing number of studies in the addiction literature suggests that tDCS modulates subjective self‐reported craving through stimulation of dorsolateral prefrontal cortex (DLPFC). The major goal of this study was to explore effects of bilateral DLPFC stimulation on resting state networks (RSNs) in association with drug craving modulation. We targeted three large‐scale RSNs; the default mode network (DMN), the executive control network (ECN), and the salience network (SN).
