The scientific team of the laboratory is engaged in a comprehensive study of topical
issues of psychophysiology aimed at estimating human functional state. Research areas of the
laboratory include the study of the systemic activity of the brain, cognitive processes (memory,
attention), as well as the assessment and correction of various emotional states using modern
technologies, including virtual reality (VR) technologies.
Another direction of the laboratory is biomedical research in cooperation with «Precision
Sensors & Instruments» Ltd. (PSI Ltd.). Various types of ultra-sensitive sensors developed by
PSI Ltd.
are used in research to assess human functional state and to develop the most affordable
methods for diagnosing and monitoring diseases. These sensors can find their application in the
field of practical healthcare.
Special attention is paid to the implementation of new approaches into the study, the
development of methods for determining the most informative criteria for a multilateral
assessment of the functional state.
Research methods used in the laboratory:
- Psychological tests - (Taylor, Pichot, Eysenck questionnaires) to assess the level of
anxiety, depression, hypochondria, asthenia and determine the type of temperament of the
subjects
- Psychophysiological tests, which are used to study the processes of voluntary attention
and memory, the temporal characteristics of brain processes of information processing (the speed
of simple and complex visual-motor reactions)
- Polygraphic registration of physiological parameters (EEG, ECG, skin conductance,
blood volume pulse, respiration, temperature, analysis of heart rate variability and study of
systemic hemodynamics) in order to assess the autonomic support for mental activity
- Methods of exposure:
Exposure to an immersive environment generated by virtual reality (VR)
technology
Exposure to audiovisual stimuli
Micropolarization of the brain.
