Overview
In this within-subjects, crossover study, participants will undergo Electroencephalogram (EEG) recordings before, during, and after each of three 1-hour sessions. All participants will experience all three conditions: (1) dual-frequency visual (10 and 40 Hz), (2) single-frequency visual (40 Hz), and (3) non-rhythmic stimulation. EEG spectral power and amplitude coupling will be analyzed to determine whether stimulation-induced increases in alpha-gamma neural synchrony translate to improvements in cognitive performance.
