also included a novelty vertex source for factor 241 (FCz, Cz, C1/2, CPz), and a secondary lateral frontal source topography (AF7/8, F7/8). ANOVA models for each of the midline topographies included group (patient, control) as a between-subjects factor and site (all electrode sites within the region) as a within-subject factor, or hemisphere (left, right) and site for topographies displaced from the midline. Even though the age difference between groups was small, significant ANOVA results were confirmed using age as a covariate.
