Alpha and Theta Oscillations Are Causally Linked to Interference Inhibition: Evidence from High-Definition Transcranial Alternating Current Stimulation

(1) Background: The Go/NoGo task and color-word Stroop were used to investigate the effect of applying different frequency bands neural oscillations lDLPFC on inhibitory control modulation. (2) Methods: Participants randomly categorized into four groups received HD-tACS at 6, 10, 20 Hz or sham stimulation 1.5 mA for min. All participants performed a before immediately after stimulation; closed-eye resting-state EEG signals acquired 3 min tasks. (3) Results: There no significant differences in behavioral indices across groups. In task, response time was significantly reduced by 6 10 stimulations compared stimulation, accuracy stimulation. range-specific (delta, theta, alpha, beta, gamma) resting power (4) Conclusions: effectively improved participants’ performance demonstrating importance interference inhibition supporting causal relationship between theta alpha inhibition.
