The results of the omnibus ANOVAs are presented in Table 4. Similar to the power analyses, we conducted one overall omnibus ANOVA that included all frequencies to examine differences among regions. For intra-hemispheric coherence, this revealed a significant main effect of Region (F(5,1690)=4.50, p=.004). Pairwise contrasts revealed that intra-hemispheric coherence was maximal between central-parietal and minimal between frontal-parietal regions. For inter-hemispheric coherence, the main effect of Region was also significant (F(3,1014)=4.83, p=.004), with maximal inter-hemispheric coherence in the temporal region, and minimal coherence in the central region. Figure 2 depicts the strength of coherence within and across hemispheres for each group.
