Neurophysiology Data of Cognitive Training in Immersive Environment

A study of the cognitive status of relatively healthy young volunteers was presented in this paper. Cognitive status assessment is based on the study of electrophysiology and eyetracking (ET) signals during cognitive training in an immersive environment (virtual reality). The methodology of the experiment, the process of dataset formation and methods of data analysis are described. Several parameters of biological signals (EEG, ECG, ET) related to cognitive functions (attention concentration, working memory, reaction speed, motor control, hand-eye coordination) were identified. EEG and ECG signals were obtained using a 19-channel electroencephalograph “Neurosoft”. While eye tracking data (26 parameters) was extracted from the built-in eye tracker in virtual reality glasses HTC Vive Pro Eye. An open database on the conducted research was developed and published. A comparison of similar published studies is provided in the discussion section of the paper. The project is intended to involve more subjects and to apply machine learning algorithms to the analysis of biosignals. Consequently, an objective system will be developed to assess cognitive status based on biological signals.
