We examined 102 patients with symptomatic, cryptogenic, and idiopathic forms of epilepsy in order to investigate the physiological mechanisms providing the efficiency of purposeful activity in patients with this disease. Three clusters of patients were formed with the use of the Gorbov-Shulte performance test. The patients of "low efficiency" clust...

Using spectral, wavelet, multifractal, and recurrence analyses we examined the features of involuntary shaking (tremor) arising during the performance of a given motor task. The task was to maintain the efforts of fingers under isometric conditions by a healthy subject, a patient with primary bilateral parkinsonism, and a patient with a syndrome of...

We studies the differences in oscillatory responses to emotional facial expressions in 40 subjects with different severity of depressive symptoms (19 men and 21 women) aged 18-30 years. In subjects with low severity of depressive symptoms (group 2), the perception of happy facial expressions was marked by lower delta synchronization as compared wit...

We studied the interrelations between G/A-polymorphism of EPAS 1 gene(rs1867785) and macimal oxygen consumption (VO2max) in Russian male athletes. There were two groups in the study: athletes of different sport specialization (n = 241) and nonathletic males (n = 92). It was found that the frequency of AA and AG genotype of EPAS1 gene in the group o...

The mechanisms underlying the locomotion recovery in poststroke patients remain unknown. Navigated transcranial magnetic stimulation (nTMS) is a new method to evaluate the functional state of the motor system. Using of the exoskeleton complex (EC) allow to correct walking pattern significantly. The aim of this study was to evaluate the capability o...

We performed a comparison of the results of recognition of fragmented outline images in the presence of noise and without it. Contour images and visual noise were synthesized form Gabor elements. Distances between the Gabor elements in contour and in noise were changed and image sizes varied too. The percentage of correct responses was not dependen...

Alcohol-induced muscle damage (AIMD) - an umbrella term that includes all forms of alcoholic myopathy developing in acute or chronic alcohol intoxication. The most common form of destruction of skeletal muscle in alcoholism is a chronic alcoholic myopathy, which develops independently of other manifestations of alcoholism, such as polyneuropathy, m...

Correlations of 25-hydroxyvitamin D, or 25(OH)D, serum concentration with the blood levels of total cholesterol (TC), high-density lipoprotein cholesterol, triglycerides (TG), and apolipoprotein E were analyzed in young non-overweight men (n = 40) and females (n = 61) aged 14–23 having no excess body mass. The measured variables have been standardi...

The method is described for joint use of electroencephalography and near-infrared spectrography for location of sources of electrophysiological and focuses of hemodynamic brain activity during motor execution and imagination. The sources of electrophysiological and focuses of hemodynamic activity the most relevant for controlling the hybrid brain-c...

Multisegmental muscle responses (MMR) are reflexes in the leg muscles evoked by transcutaneous electrical spinal cord stimulation over the Th11–Th12 vertebrae. We have used MMR to evaluate the excitability of lumbosacral motor neurons in individuals suffering lower paraplegia. Ten individuals were tested using H-reflexes and MMR bilaterally before ...
