Study Summary
This is a single-blind randomized within-subject crossover design study that will be conducted in 2 phases. In Phase 1, up to 50 participants, after signing informed consent and determining eligibility, will undergo a baseline EEG and cognitive assessment. In Phase 2 participants will undergo tACS at IAF+2Hz, IAF-2Hz, and IAF during a double-flash illusion task in a randomized order. The tACS will be applied with a current of 1-2 mA (milliamperes) via two saline soaked electrode sponges (25 cm²) applied to the back of the head. The investigator's hypothesis is that participant's will perform better on the visual task while tACS is set to 2 Hz above their IAPF, relative to tACS set to 2 Hz below their IAPF.
Primary Outcome
Participants are instructed to fixate their gaze on a central fixation cross. When the cue appears, a low-luminance disc stimulus flashes on either side (left or right) of the fixation cross. The disc can flash one or two times. After the stimulus ends, participants are cued to make a response regarding the number of disc flashes (1 or 2). Participants will undergo 300 trials. Participants will be scored on response accuracy (i.e., number of correct responses out of 300 possible responses).
Interventions
