Aperiodic RS-EEG activity
SE
When using a directional hypothesis, based on the only other tRNS study that examined its effect on aperiodic exponent, significant changes in the aperiodic activity in Fz were seen following active compared to sham tRNS (β = −0.11 (SE = 0.06), t(20) =−1.99, Finally, there was a significant correlation between change in activity from t2 to t0 in the periodic beta bandwidth averaged over the frontal area and the aperiodic exponent measure across the entire sample (
