[Galvanic vestibular stimulation in physiological and clinical studies in recent years].

Galvanic vestibular stimulation is a simple, harmless, noninvasive and low-cost research technique. In spite on a long history, it has been recently found popularity as a research tool. At present occurs of its revival as a research and diagnostic tool.

[Trends in hospitalizations of patients with acute coronary syndrome and indicators of the atmospheric state in Moscow in 2009-2012].

Aim: To identify the meteorological factors or their combinations, which are most significant for the development of acute coronary syndrome (ACS) in different seasons.

Subjects And Methods: A Statistica package was used to make an exploration analysis of the data of the A.S.

[Specifics of activation of cortex by stimulation of support receptors in healthy subjects and in patients with lesions of CNS].

Results of basic studies in space medicine revealed the mechanism of motor disorders and the importance of support input in regulation of the tone and posture system of the mammals. Progress in functional magnetic resonance tomography (fMRT) enabled in vivo estimation of activity of various parts of the brain during stimulation of support afferent pathways. The goal of our study was to detect specific activation of the cortex during stimulation of support input in healthy subjects and in patients with lesions of CNS.

[Mechanical stimulation of soles' support zones: non-invasive method of activation of generators of stepping movements in man].

The effects of mechanical stimulation of the soles' support zones in regimens of slow and fastwalking (75 and 120 steps per minute) were studied using the model of supportlessness (legs suspension). 20 healthy subjects participated in the study. EMG activity of hip and shin muscles was recorded.

[The effects of support-proprioceptive deprivation on visual-manual tracking and vestibular function].

To determine the effects of support and proprioceptive afferentation on characteristics of the visual-manual tracking (VMT) we used a model of weightlessness - horizontal "dry" immersion. Altogether 30 subjects who stayed in immersion bath from 5 to 7 days were examined to evaluate the accuracy of VMT in tasks to pursue the jerky (saccadically) and smooth (linear, pendular and circular) movement of a point visual stimulus. Examinations were performed before, during and after immersion using electrooculography (to record eye movements) and a joystick (to record hand movements) with a biological visual feedback - one of the two visible stimuli on the screen matched the current angle of the joystick handle.
