Psychophysiological Functions

The study is devoted to assessing the psychophysiological adaptive capabilities of students of higher medical institutions. There was conducted a screening study on the basis of which a correlation analysis of a group of 42 students was performed. The main inclusion criterion was good physical activity. Exclusion criteria - the presence of chronic diseases, acute respiratory viral infections at the time of examination, taking antidepressants or psychoactive substances. The study was aimed to identify the peculiarities of changes in psychophysiological functions and the state of adaptive capacity of students of higher medical institutions being in stressful conditions. The following methods from the software and hardware complex "Psycholot-1" were used for the study: "Functional mobility of nervous processes according to Khilchenko" and "Memory." The survey was conducted under micro-stress, it means all tasks had to be completed in a limited period. Statistical analysis of the data was performed to establish correlations between psychophysiological indicators of short-term memory and functional mobility of nervous processes  (Spearman's rank correlation index). It was found that the faster the stimulus appears in conditions of time deficit, the lower the mobility of nervous processes in the student, which is directly reflected in the indicators in increasing the minimum exposure time of the figure on the screen (0.27±0.007 s). In addition, a relationship was found between the rate of reaction of the left hand to a stimulus and the amount of information that a person can store in short-term memory. The information obtained will help to determine the initial data of the adaptive capacity of a potentially healthy contingent of people and predict their success in further professional activities in the sphere of medicine.

Interpretation Of Change

This investigation is not concerned with the clinical indications or results of prefrontal leucotomy, but attempts to re-examine changes following the operation, especially in regard to the impairment of some of the manifestations of the highest integrative psychophysiological functions of the central nervous system that may bring about such alterations. Amongst these we were primarily interested in cognitive changes, but the interpretation of apparent cognitive changes led to the consideration of orectic alterations as well. Such changes have so far been impossible to localize exactly, but are considered to be partly related to the phylogenetically more recent parts of the cerebral cortex. Masserman (1946) compared the mechanism of shock treatment and leucotomy with the effects of alcohol and states that “its main actions are those of a cortical depressant,” as manifested by impairment of finer perceptions and discriminations and a “constriction of the integrative field.” He believes that shock therapies and leucotomy partly produce their results by temporary or permanent decorticating effects, “rendering the individual no longer capable of fine spun fantasies or elaborate delusions.” These decorticating effects can be assumed to be reflected in cognitive, conative and emotional alterations following the operation. The interpretation of change following leucotomy presents many difficulties, one of them being that only dysfunction can be related to structural damage of the frontal lobe and not function. Another is that psychotics or severe neurotics operated upon usually do not have a sufficiently intact pre-operative personality to draw conclusions about the normal functions.

BackgroundThere is no unequivocal estimation of influence of synthetic cannabinoids on health of the users, their influence on neurocognitive functions and their correction with use of microwave resonance therapy (MRT).ObjectiveTo evaluate dynamics of pathological craving and neurocognitive functions in patients with dependence on synthetic cannabinoids during use of MRT.Materials and methodsThirty-two patients (main group with dependence on synthetic cannabinoids with MRT) and 38 patients (control group with medication and without MRT) were examined. Craving was evaluated with “Drug Craving Scale”; efficiency with CGI. For evaluation of psychophysiological functions we used methods: “number square”, ‘balance-tranquility’, “verbal memory”, “linear visual estimation”, “exclusion of the word”.Results and discussionAfter therapy, stopping of symptoms of pathological craving was observed in the main group as 29.6% as more than in control group, improvement according to CGI as 37.1% as more than in control one. The evaluation of neurocognitive indicators was conducted. Attention: in the main group improved by 11 ± 1.3 points; in control one by 7 ± 3.1 points. Level of activation: in the main group decreased by 16 ± 2.9 points; in control one by 9 ± 3.5 points. Memory in the main group improved by 3 ± 0.21; in control one by 2 ± 0.3 points. Perception: in the main group improved by 1.5 ± 0.2; in control one by 0.8 ± 0.12 points. Thought: in the main group improved by 14.0 ± 1.6; in control one by 6.4 ± 1.1 points. Thus, it was shown that during use of MRT both perception and processing of information, improve in complicated conditions, reduction of pathological craving accelerates.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Psychophysiological Functions

Introduction. Visual impairment is the most common disturbances during the child development in preschool and primary school age. Such children need care with the health-improving technology based on scientific knowledge about the characteristics of their psychophysiological functions. The aim of the study is to identify development-related changes in blood circulation and central nervous system functions in 4-10 year healthy children and cases with visual impairments. Materials and methods. A total of 380 children were examined by electrocardiography, electroencephalography, registration of neurodynamic processes, analysis of the tactile function, and self-assessment of anxiety. Results. In subjects with visual impairment, an increase in age-related heterochronism in the development of psychophysiological functions was revealed. The accuracy indices of time intervals and tactile sensitivity of the skin of the fingers were higher, and the indices of physical development, kinematometry, and mobility of nervous processes in many age groups are lower than in healthy ones. Such adaptive changes were accompanied by an increase in functional stress. So, for example, in preschool children from 4 to 6 years, when analyzing the structure of the heart rhythm, an increase in the values of the stress index was noted (from 148.08 ± 3.32 to 220.08 ± 3.62 c.u.; p < 0.05). Conclusion. Judging by the high values of activity indices of the central mechanisms of heart rhythm regulation, anxiety, and the nature of bioelectric changes on the EEG, the “price” of age-related adaptation in children with sensory impairments rises. It contributes to the development of disadaptation. The conclusion is made about the need to develop effective means of psychophysical correction of children with visual impairments, taking into account the nature of age-related changes.
