Measurements of Electroencephalogram (EEG), Galvanic Skin Resistance (GSR) and Heart Rate Variability (HRV) during the Application of a System that Gives Simultaneously tVNS and Brain Entrainment on Subjects Affected by Depression and Anxiety

Abstract

The application of tVNS plus Brain Entrainment is expected to rapidly reduce the sympathetic activity and increase the parasympathetic activity. In this study, analysis of the system by a complete poligraphy consisting of HR, GSR and EEG demonstrated that a combined stimulus of supplement Cream + tVNS + Brain Entrainment and light blocking was able to produce a dominant parasympathetic state mixed to a drastic reduction of sympathetic activity in cases of depression, anxiety and stress.
