Figure 4.

Coherence of the affected and unaffected hemisphere. Coherence of three sine models and two optimal signal models are displayed per subject and as a mean over the whole group for the unaffected hemisphere (left panel) as the affected hemisphere (right panel). All models showed a significant difference between the both hemispheres (P < 0.05). For the sine models, coherence in the unaffected hemisphere increased significant with the implementation of a voxel‐wise delay. Difference analysis showed a significant positive increase in the affected hemisphere after implementation of a voxel‐wise phase. Frequency‐adjusted sine shows only in the unaffected hemisphere a significant increase in coherence after difference analysis. A significant coherence difference between the sagittal sinus and unaffected hemisphere was found for both hemispheres (P < 0.05).
