132 Chapter 6 Although at face value time seemed to substantially affect the regional coherence spectra due to the large spectral differences between T1-T2-T4, none of the repeated measures models reached significance for the changes in beta and alpha connectivity (p>0.06). Similarly, no effect of time was found for wPLI alpha and beta band connectivity (p>0.08). Figures 6 and 7 show the coherence and wPLI scalp topography for AN at the 3 time points as well as the HC in the alpha and beta frequency range. For coherence, no large changes in the topography can be seen, despite a change in overall connectivity. Figure 6. Topography of Coherence. For each electrode, the connectivity in the alpha (left) and beta (right) bands are shown, averaged over each electrode’s connectivity with all other electrodes. Top three rows are for the three timepoints T1, T2, T4. Bottom row is for HC.
