[Computer tests for research of the oculomotor reactions in patients with complains of dizziness]. / Komp'iuternye testy dlia issledovaniia glazodvigatel'nykh reaktsii u bol'nykh s zhalobami na golovokruzhenie.

New methodological principles for a study of vestibular function, intersensory interactions, and eye tracking function are proposed by parameters of spontaneous oculomotor responses and those induced by visual and vestibular stimuli using the series of computer stimulating programs, which provided polymodal, separate and combined stimulation of the visual and vestibular inputs for the OCULOSTIM unit. The method suggested allows to objectivity the subjective complaints of dizziness and equilibrium disturbances, to differentiate diagnosis of cerebral organic process and psychogenic disease of central nervous system (CNS), and to specify physiological systems involved in their pathogenesis as well as to diagnose subclinical cerebral vestibulopathy. Qualitative and quantitative characteristics of eye tracking movements with and without a visual background (retinal optokinetic stimulation) are the most informative in the differential diagnosis of organic and functional psychogenic CNS disturbances.

[Individual characteristics of correction of the cosmonauts' vegetative status with a method of adaptive biofeedback]. / Individual'nye osobennosti korrektsii vegetativnogo statusa kosmonavtov s pomoshch'iu metoda adaptivnogo bioupravleniia.

The ability of 4 cosmonauts to voluntarily control their physiological parameters during the standing test was evaluated following a series of the adaptive feedback (AF) training sessions. Vegetative status of the cosmonauts during voluntary "relaxation" and "straining" was different when compared with its indices determined before these sessions. In addition, there was a considerable individual variability in the intensity and direction of the AF effects, and the range of parameters responding to AF. It was GCR which was the easiest one for the AF control.

[Correction of autonomic reactions parameters in organism of cosmonaut with adaptive biocontrol method]. / Metod adaptivnogo bioupravlenia dlia korrektsii parametrov vegetativnykh reaktsii organizma kosmonavtov.

Presented are results of testing the method of adaptive biocontrol during preflight training of cosmonauts. Within the MIR-25 crew, a high level of controllability of the autonomous reactions was characteristic of Flight Commanders MIR-23 and MIR-25 and flight Engineer MIR-23, while Flight Engineer MIR-25 displayed a weak intricate dependence of these reactions on the depth of relaxation or strain.
