The correlation between baseline prestimulus brain activity and anxiety change in single-session transcranial Direct Current Stimulation

Objectives: Transcranial Direct Current Stimulation (tDCS) on the left dorsolateral prefrontal cortex (LDLPFC) has been shown to moderate anxiety. However, the effect of tDCS has high variability, and it is considered that the effectiveness differs depending on the individual differences. The possibility of using tDCS would greatly benefit if we could predict the effect of tDCS for anxiety before stimulation.
