In order to determine the spatial-frequancy characteristics of the visual system of healthy subjects and patients with schizophrenia, we used the contrast comparison of two Gabor gratings with sinusoidal distribution of brightness. The Gabor gratings have low, medium or high spatial frequencies; the neurons of magnocellular and parvocellular channe...

The experimental study of psychophysiological parameters of the central nervous system (CNS) has been performed in the adolescents who combine the learning-educational and sporting activities. The differences in psychophysiological indices in dependence on the intensity level of sporting loads have been revealed in the trained and non-trained adole...

It was the objective of this research to study the functional parameters of endurance and performance and the brain electrobiological activity during local antebrachial muscle work performance among skilled athletes and unfit people aged 18-23. We examined performance and the brain bioelectrical activity changes at local muscle work by means of an ...

Investigations were carried out on 36 patients with reactive depressive states and repeating depressive episodes with severe manifestation of anxiety syndrome. The spatial organization of brain activity by cross-correlation analysis was studied. Shown, that clinical depression and anxiety syndrome is reflected in the structure of the spatial organi...

Unconscious perception essentially affects human behavior. The main results in this area obtained in experiments with visual stimuli. However, the acoustical stimuli play not less important role in behavior. The main idea of this paper is the electroencephalographic investigation of unconscious acoustical stimulation effects on electro-physiologica...

The purpose of this work was to study the reactivity of EEG mu-rhythm during observation, auditory perception and imitation of circular hand movements with a computer mouse, and its correlation with empathic ability of an individual. During observation of hand movements, we discovered a significant desynchronization of the mu rhythm in the hemisphe...

Chronic alcoholic myopathy occurs in 40-60% of patients who abuse alcohol, and is accompanied by decreased performance, proximal paresis and atrophy of skeletal muscles. However, it is unknown what is important in the development of the disease: duration of alcohol abuse, or the dose of ethanol consumed. Unknown dynamics of the pathological process...

The article presents data on new approaches to the application of the surface electromyogram based on the nonlinear dynamics of complex systems. Special focus is placed on applicability of nonlinear parameters for early and differential diagnostics of Parkinson's disease, various kinds of tremor, schizophrenia, as well as for the estimation of norm...

The level of endotoxin and indicators of activity of antiendotoxin immunity (antibody concentration to glycolipid Re-chemotype and general antigen of enterobacteria) were estimated in serum of 174 patients with persistent viral infections (viruses: herpes simplex, hepatitis C, human immunodeficiency). The presence of markers of systemic inflammator...

The article deals with a new medical technhique for the assessment of autonomic regulation of internal systems and skin. We suggest investigating skin sympathetic nervous activity by the method of electrodermal testing of skin sympathetic reactions. It has been showed that current of 200-250 microamperes and 12 volts is optimal for testing the skin...
