Features of the correlation between two-sided electrodermal activity and EEG spectrum power

The paper considers the correlation between two-sided electrodermal activity and brain activation, as well as the correlation between the asymmetry of electrodermal activity and the asymmetry of the cerebral hemispheres. Aim. The paper aims to identify the correlation between electrodermal activity and EEG spectrum power so to compare the asymmetry of electrodermal activity and the asymmetry of the cerebral hemispheres. Materials and methods. The sample consisted of 30 people aged from 18 to 25 years (18 males and 12 females). Electrodermal activity was assessed by the method of nonspecific endodermal response (by Tarkhanov) with the help of the Activatsiometr AC-9K system proposed by Yu.A. Tsagarelli. EEG recording was performed using a 64-channel electroencephalograph (actiCHamp-64) and the Brain Products PyCorder package. Results. The features of the correlation between electrodermal activity and brain activation were found in all frequency bands. Most of the correlations were associated with the left hemisphere. The asymmetry of electrodermal activity correlates with the asymmetry of brain areas associated with electrodermal activity.
