Fig. 2: Scalp topographical mapping of percentage change in EEG power following rhythmic and patterned stimulation paradigms across frequency bands.

The difference in power pre-post stimulation was plotted on the scalp axial projection, with each row corresponding to a specific stimulation frequency band. The first three rows represent rhythmic stimulation at theta-RS (3–7 Hz), alpha-RS (7–12 Hz) and beta-RS (12–20 Hz) while the fourth row illustrates PS. Columns represent the response frequency bands (from left to right): delta (1–3 Hz), theta (3–7 Hz), alpha (7–12 Hz) and beta (12–20 Hz). Scalp regions are color-coded indicating percentage changes in power ranging from -10% (blue) to +10% (red). Regions exhibiting statistically significant pre-post differences, as determined by the linear mixed model, are marked with black stars.
