Scientific priorities of the laboratory

  • Main direction of the laboratory investigations: a study of neuro- and psycho-physiological mechanisms of human personality formation, correction of unfavorable psycho-physiological states with a help of electroencephalogram biofeedback (EEG-biofeedback), analysis of neural mechanisms of individual brain wave pattern activity and effects of EEG-biofeedback.
  • Currently the laboratory is going to realize a project directed to study the mechanisms of negative changes of emotional and higher cognitive functions in their interrelation in children and adults, elaboration of new methods of diagnostics and correction of the above mentioned functions by using color and audio stimulation with feedback on EEG parameters on basis of portable automated complex and original software.
  • Project validation: it is known that mismatch of qualifying standards and abilities of an individual, absence of people encouragement lead to stress development in children and adults. Stress development and its transition to distress are accompanied by increased anxiety, depression and other unfavorable psycho-physiological states. These changes might be a cause of violation of some functions of cognitive sphere. Previously, in our investigations it was shown that peculiarities of manifestations of some emotional state indexes (level of anxiety, aggression) and degree of separate cognitive functions development (voluntary attention) specifically reflected in EEG pattern and event-related potentials (ERP). Also it was shown that a person participating in several EEG-biofeedback sessions can be taught to voluntary change power and frequency of EEG rhythms, their spatial localization and as a result reduce level of anxiety in children and adults, enhance level of voluntary attention development. It is found out that a decrease of situational and personal child anxiety gained as a result of such sessions is accompanied by efficiency improvement of several kinds of activity (school results, elements of social interactions). A correlation between frequency of dopamine neuron impulse activity of cat’s midbrain and EEG time-spatial characteristics of neocortex was revealed in experiments on cats. The above mentioned experiments allow evaluating neurons contribution of specified brainstem aminergetic system in forming of current EEG pattern that allows outlining paths for purposeful EEG-biofeedback protocol selection.

Main project tasks are as follows:

1. To develop new methods of objective psycho-physiological human state estimation on basis of EEG and ERP registration using data-intensive, emotional stimuli presented from a monitor screen, and also speech stimuli in a process of social interaction.

2. To study the mechanisms of psycho-physiological state violation on the whole and higher cognitive functions in children up to 12 years of age (including orphans) experiencing serious learning difficulties and social adaptation by using EEG and ERP registration.

3. To study the mechanisms of higher cognitive function violation in adults (including students and the clients of psychological consulting) experiencing serious learning difficulties and being in a state of emotional and information stress by using EEG and ERP registration.

4. To study the mechanisms of neocortex interaction, ventral tegmentum dopamine neurons, serotonergic raphe nucleu neurons and noradrenergic locus caeruleus brainstem neurons during EEG-biofeedback sessions in the model experiments.

5. To develop new technologies of emotional state correction and higher cognitive functions correction applying color and audio stimulation with feedback on EEG parameters.
