Comparison of source-resolved versus scalp channel data. (A) One cluster of Independent component (IC) source locations and corresponding cluster mean event-related spectral perturbation (ERSP) time/frequency measures for a spatial working memory task performed by 43 ADHD and 43 typically developing (TD) children 7–14 years of age. Results for low and high memory load conditions are shown. (B) Equivalent ERSP measures for nearest scalp electrode channel Oz. Topographical distribution of the alpha band activity (in black dashed boxes) during the Encoding (E) time window are shown on the cartoon heads
