Patterns of the electrical activity of the brain in the ultraslow bandpass were registered by two groups of young students of psychology, practically normal, urban dwellers. The registration, which took about 15 to 20 minutes in each case, was conducted twice, with eyes closed, first prior to passing a course of psychological correction, and second, right after it. The course was two week long, 1.5 hours a day. It comprised listening to either random sounds of nature (control group) or, to familiar music (main group). Two basic trends in dynamics of mean spectral power of signals were demonstrated for members of the main group: if the initial level of ultraslow activity was high, it tended to fall as a result of passing the course; if the initial level was low, it tended to rise. As a result, sort of ‘fine tuning’ of the activity of the brain took place, which was not the case of the control group. In terms of physiology, the overall functional state of members of the latter tended to pass moderate activation. As to the members of main group, their functional state passed more sophisticated tuning, depending on its initial level. Presence of such tuning, forming part of normal adaptive capacity. was corroborated by data of molecular biological survey.

Optimization of the psychophysiological state of the specialist of the future by means of applying procedures of psychological correction forms a highly actual topic of present-day scientific research. Their verification at the level of brain structures and mechanisms seems to be most constructive and expedient. Electrophysiological registration of the dynamics of brain waves provides a relevant approach for the implementation of this approach. Joining the psychological correction with detailed study of underlying brain mechanisms of its effectiveness forms the main topic of the present research.
Spectral analysis of quick forms of brain activity, belonging to the realm of electroencephalography, which deals with periodic electric processes ranging from 1.5 to 30 Hertz, in the course of psychological correction of different kinds or, following it, has been quite studied by present time rather extensively. As to the so-called ultraslow activity, that is, electric processes ranging from 0 till 0.5 Hertz, it has been studied by now in an insufficient way. At the same time, ultraslow activity of the brain is currently regarded as being basic for the stabilization of functional state of the organism in general (Aladzhalova, 1979; Bekhtereva, Gogolitsyn, Kropotov, & Medvedev, 1985).
Thus, linking patterns of dynamics of ultraslow electric activity of the brain with different types of psychological correction in normal seems to be a constructive topic for systematic interdisciplinary research.
Research questions of the present study are the following ones:
Do different types of psychological correction regularly produce different types of brain activity at the level of ultraslow electric processes?
Do optimal types of psychological dynamics, induced by the application of psychocorrection procedures, have brain correlates of their own, at the level of ultraslow activity?
Purpose of the Study
Purpose of the study consisted in conducting the following procedures:
Routine medical testing of 40 young, practically healthy Russian-speaking urban dwellers, aged 23±3 years, which ended with subscription of the routine form of informed consent. All of the respondents were students at bachelor or master programs, intending thus to become specialists in psychology and neighbouring realms (e.g. counceling) (for overview of psychological attitudes of this societal group, see Obukhova & Obukhova, 2015). A sample of blood (5 ml) of each subject was taken, as part of the medical testing, which allowed us to conduct molecular biological analysis, including detection of telomere length (results of this part of the study were already published by us as separate paper);
Psychological testing was conducted in each case, by means of standardized questionnaires. It was focused upon the dynamics of mood, tension, general psychological activation, as well as the level of neuroticization (results of this part of the study also were already published by us as separate paper);
Initial registration of the electric activity of the brain in the ultraslow and electroencephalography bandpasses;
Passing a two-week course of sound (non-music) therapy, 1.5 hours a day (control group 1); passing a two-week course of music therapy, 1,5 hours a day (group 2), Each of the groups consisted of 20 randomly chosen respondents. Both audiocourses were conducted with the help of sets of sound/music tracks, recommended for the purpose of relaxation by the Federal Ministry of Health of Russia;
Routine medical testing of the 40 respondents, blood sample (5 ml) were taken;
Another run of the psychological questionnaires was conducted;
Final registration of the electric activity of the brain in the ultraslow and electroencephalography bandpasses;
Data processing and interpretation of results obtained, as a result of study of psychological dynamics occurring as a result of passing a course in psychological correction, and its brain correlates.
Brain activity was registered with the help of a 32-channel digital electroencephalograph, produced by Mitsar (St.Petersburg, Russia), from 19 electrodes, fixed at a special helmet, produced by MCS (Zelenograd, Russia), by 10-20 system. Electrode resistance did not exceed 50 kOM
Registration of brain activity and analysis of data obtained was conducted with the help of a special analytic program, elaborated by V.Ponomarev and J.Kropotov at Human Brain Institute, Russian Academy of Sciences in St.Petersburg, Russia, state registration No. 2001610516, of May 08, 2001. The program was applied by permission of the authors. In each case, the registration was done with eyes closed, in an isolated box, and took 15 to 20 minutes.
Notes: data present mean spectral power of signals from 19 electrodes, adjusted by logarhythmic scale. Prior – mean spectral power before passing a course of psychological correction, post - mean spectral power after passing a course of psychological correction, subgroup 1a – subgroup of respondents who initially had statistically relevant high level of mean spectral power of signals at the ultraslow bandpass, and passed after that a correction course of random sounds; subgroup 1b - initial low level / correction course of random sounds; subgroup 2a - initial high level / correction course of familiar music; subgroup 2b - initial low level / correction course of familiar music.
