How does vagal nerve stimulation (VNS) change EEG brain functional connectivity?

How does vagal nerve stimulation (VNS) change EEG brain functional connectivity?

Highlights • Intracerebral functional connectivity(Fc) was estimated in five patients who underwent SEEG recordings during ongoing VNS therapy. • In comparison with OFF periods, the ON periods disclosed higher synchronization values for four patients and lower values for one patient. • Decreased Fc...

Zusammenfassung:Highlights • Intracerebral functional connectivity(Fc) was estimated in five patients who underwent SEEG recordings during ongoing VNS therapy. • In comparison with OFF periods, the ON periods disclosed higher synchronization values for four patients and lower values for one patient. • Decreased Fc was observed only in the responder patient.
