30 Hz High-Definition Transcranial Alternating Current Stimulation at the Left Frontal Cortex Reduces the Spectral Slope of the EEG in the Contralateral Hemisphere
Orestis Stylianou, Basak Senel Kara, Joachim Behr
This study applies HD-tACS to the left frontal cortex and finds it reduces the spectral slope of EEG in the contralateral hemisphere, suggesting changes in neuronal dynamics and potential as a biomarker.
