Zusammenfassung
Phase synchronization plays an important role both under physiological and pathological conditions. With standard averaging techniques of MEG data, it is difficult to reliably detect cortico-cortical and cortico-muscular phase synchronization processes that are not time-locked to an external stimulus. For this reason, novel synchronization analysis techniques were developed and directly applied to MEG signals [1]. However, due to the lack of an inverse modeling (i.e., source localization), the spatial resolution of this approach is limited. To detect and localize cerebral phase synchronization, we developed the…
