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

Thedevice that we have used, is a system realized by the NuCalm  designed with the purpose to treat subjects affected by depression, anxiety, stress. The whole system consists of four components that leverage biochemistry, neurophysiology, and physics to obtain and maintain parasympathetic nervous system dominance. Previously, we have performed an HRV analysis just on tVNS only. Let us express how the four components work together. First, NuCalm topical cream is applied to the carotid on the neck and it is designed to act counteracting adrenaline. It includes structured, nutrient-sourced building blocks (Active ingredients are PharmaGABA, Lactium (Casein Tryptic Hydroylsate), L-Theanine and L-Tyrosine) that rapidly create a natural relaxation response. Second, the system uses the micro current stimulation patches, a tVNS system that is placed behind each ear at the Mastoid Process. Research has shown that this device induces an increase of parasympathetic response. Next, a noise- dampening headphones.

are used to deliver proprietary nonlinear oscillating neuroacoustic software to bring the brain wave pace to the pre-sleep stages (12Hz -4Hz) via brain entrainment. Finally, Light-blocking eye masks are used to negate visual stimuli. The aim of the present paper is to study the combination of these four components in subjects having Psychological Disorders (P.D.) as depression and anxiety. We have studied the Electroencephalogram (EEG), the Galvanic Skin Resistance (GSR) level and the HRV during the complete treatment in subjects affected by anxiety and/ or depression.


Solace Lifesciences, Inc., of Wilmington, Delaware, USA, furnished the NuCalm device. 100 young subjects affected by anxiety, or depression were examined. To test the subjects each potential participant was given a nonstructured interview following the criteria of the Diagnostic and Statistical Manual of Mental Disorders (DSM-V). Participants selected for the study showed symptomatology of anxiety or depression.
