Natural environment experiences in virtual reality (VR) can be a feasible option for people unable to connect with real nature. Existing research mostly focuses on health and emotional advantages of the "virtual nature" therapy, but studies of its neuropsychological effects related to visual perception are rare. In our experiment, 20 subjects watched nature-related video content in VR headsets (3D condition) and on a computer screen (2D condition).

Our paper considers the organization of fluid intelligence and psychometric indicators of creativity and is based on the experimental data obtained for children aged 11 ( = 99) and for young adults ( = 77). We used two figural and verbal tasks with and without time limit.

To study the effect of information load during training of visual-spatial memory in conditions of distributed attention, the dynamics of memory and attention indicators was analyzed during ten training sessions in groups of twenty-year-old (GrY) and sixty-year-old (GrO) women. Regardless of the experimental conditions, the GrO differs from the GrY in the lower accuracy of hitting the target spatial spaced stimuli but similar indicators of attention concentration on the centrally located stimulus.

To identify predictors of cognitive reserves and methods for their determination based on the developed applied ontology, we performed a bibliometric analysis of publications contained in the PubMed database. It is shown that the annual growth in the number of publications relevant to the topic in the period 1990-2019 was 11%, which is higher than the average for science.

Objective: A special place among cognitive disorders in patients with cardiovascular diseases is given to postoperative cognitive dysfunction (POCD). The study aimed at investigating the patterns of beta-2 activity associated with postoperative cognitive dysfunction (POCD) in patients after coronary artery bypass grafting (CABG).
Material And Methods: The study included 60 patients who underwent neuropsychological testing 3-5 days before surgery and on the 7-10 day of CABG.
Sustained focusing on a negative assessment of life events can create negative background and changes in the emotional feedback to new information. In this regard, it is important to assess the balance between self-assessment of emotional memories and their reflection in brain activity. The study was aimed at exploring the brain activity using electroencephalographic (EEG) analysis in six frequency ranges from delta to beta2 during the retrieval of positive or negative emotional memory compared with the resting state.

The study involved university students and elderly women (20±1,1 and 65,1±5,8 years, respectively). The dominance of cognitive activity in the profile of motivational inducers is established regardless of the age and time period of self-assessment.

Changes of the alpha1 and alpha2 rhythms during convergent (addition in the mind) and divergent (heuristic task solving) thinking due to rational and irrational cognitive styles were studied. It is shown that the functional activity of the cerebral cortex during convergent thinking was associated with rational style and presented in parietal low-frequency alpha1 biopotentials whereas during divergent thinking - with the irrational, and this effect was produced by widespread regional and frequency differences of alpha1 and alpha2 oscillations in posterior cortex. The originality of ideas correlated with the alpha desynchronization in the posterior cortex in the persons with high intuition, whereas the persons with low intuition characterized by the alpha synchronization.

The group of elderly people differed from younger in low values of an integrated indicator physical health according to SF-36 questionnaire, especially - on scales physical and role functioning, and decreased figurative and social intelligence at relative constancy of verbal IQ. The different age-associated forms of interrelation of components of intelligence and quality of life are found: positive correlation between social intelligence and role functioning scores at senior persons; more numerous positive correlations between verbal and figurative intelligence and indicators of quality of life including integrated indicator of mental health in the thirty-year-old group; and positive correlation between verbal intelligence and values on a scale physical functioning, but negative correlations between figurative intelligence and role functioning and between social intelligence and an integrated indicator physical health for the twenty-year-old group.

Personality traits and cognitive functions were studied depending on a tumor localization in the brain in 21 neurosurgical patients and the results were compared with a control group. In patients with brain damage, mostly affected were personality traits associated with emotion regulation and social interaction (neuroticism, psychoticism and social conformity). Increases in psychoticism and decreases in neuroticism were more expressed in patients with a left-hemisphere localization of tumors.

Creativity and intelligence changes depending on tumor localization in frontal or parietal cortex before surgical procedure in 24 patients in comparison with control group are studied. Brain damage-induced intelligence impairment and a decrease of fluency, flexibility of figural divergent thinking, and originality of verbal one without specificity of tumor localization were found. Intelligence decrease was more presented while performing of figural tasks and least of all in verbal ones.

Social creativity-related topographic changes of the delta, alpha2, and gamma2 power were studied using 19-channel EEG. Originality and fluency indices of social thinking were evaluated on basis of specially developed 'divergent' task solution that stimulated different interpretations of social scenes; complex visual stimuli (architectural building) were used as control task. 'Divergent' task performing was characterized by both the greater power of the delta and alpha2 rhythms mostly in the right hemisphere and widespread increase in the gamma2 power as compared with the control task.

It was found that the alpha2 and gamma2 rhythms are specific bands which make it possible to tell the difference between social creativity and control task. Solving socially significant problems in experimental conditions is accompanied by an increase in the power of the delta and gamma2 bands and desynchronization in the alpha2 band less pronounced in divergent tasks than during the interpretation of convergent visual stimuli.
