Abbreviations: ME – main effect of diagnosis, g×h – diagnostic group by hemisphere interaction, g×BA – diagnostic group by Brodmann’s area interaction, g×h×BA – diagnostic group by hemisphere by Brodmann’s area interaction.
Uncorrected p values are followed by Huynh-Feldt corrected p in parentheses. Interactions at trend level of significance (p<0.10) are in italics. Note that parietal areas 1, 2, 3, and 5 were combined in these analyses, hence 1/2/3/5.
