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.
