Influence of Alpha Suppression on Bandwidth Confined Electric Stimulation of the Visual System

Transcranial alternating current stimulation (tACS) is an established means to modulate neural oscillations. Ongoing oscillations can hugely impact the effects of tACS. Retinofugal alternating current stimulation (rtACS) is a novel and promising application of ACS. It has already shown effects on neural oscillations outlasting the stimulation duration and a therapeutic effect on vision restoration. To optimise its efficacy, we assessed the influence of ongoing oscillations in form of alpha suppression on rtACS.
