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 high density EEG was registered in 41 healthy subjects (20 males, 21 females) in the cardinal (horizontal and vertical) and oblique (45 and 135 deg) line orientation identification task. The analysis of the adaptive amplitude maximum (4 ms averaging) of P1 and N1 evoked potentials in the symmetrical occipital, parietal and inferior temporal are...

86 patients with posttraumatic defects of median and ulnar nerves were examined. Autoneuroplasty was performed at all of patients: in 42 cases--in combination with sympathectomy (thoracoscopic clipping of Th3-4 sympathetic ganglions), in 44 cases--without sympathectomy. Ultrasonography of nerve trunks, stimulation electroneuromyography, computer th...

Effect of human Pregnancy specific β1-glycoprotein (PSG) in physiological concentrations was analyzed against the expression of natural killer (NK)-, T-cells with natural killer functions (N KT-) and T-regulatory lymphocyte (Treg) markers, as well as on the activity of monocyte indolamine-2,3-dioxygenase (IDO) and lymphocyte apoptosis in vitro. It ...

The production of drawing movements was studied in 29 right-handed children of 9-to-11 years old. The movements were the sequences of horizontal and vertical linear stokes conjoined at right angle (open polygonal chains) referred to throughout the paper as trajectories. The length of a trajectory varied from 4 to 6. The trajectories were presented ...

This paper analyzes the variation of the functional anatomy of the brain in healthy people performing identical activities on the basis of functional magneticresonance imaging (fMRI). According to the authors, this approach allows you to showcase a variety of individual strategies to achieve the same external (behavioral) result intracerebral diffe...

According to the literature data incomplete restoration of the muscular strength is observed after malleolar fractures that made us evaluate the contractile capacity of the tibial muscles after treatment of 59 adult patients with these fractures using Ilizarov method. Additionally, late follow-up of 5 cases were examined in complex. Practically, fu...

The aim of this study was to examine the effect of exhaustive weightlifting exercise on electrical and biochemical variables and performance capacity in young male subjects. The onset of exercise (80-50% 1RM) was associated with a decrease in the amount of work performed, which was followed by a steady performance capacity at 40-10% 1RM. There were...
