[Method for predicting danger induced by longitudinal accelerations in the 'head-pelvis' direction].
Aviakosm Ekolog Med
August 1994
The paper deals with the results of the studies aimed to validate the criterion of prediction of human tolerance to longitudinal tailward accelerations on the basis of structural changes in cardiac rhythm recorded directly during exposure. The experiments have been done on centrifuge with recording the sequences of cardiac intervals at rest and each stage of exposure with successively increasing intensity. Representation of basic information as two-dimensional distributions of cardiointerval durations based on the autocorrelation rhythmography method has been used.

Zh Nevropatol Psikhiatr Im S S Korsakova
March 1989
On the basis of examination of three groups of patients with Raynaud's phenomenon (RP) (Group I was composed of patients with an idiopathic forms of RP; Group II, of those with neurovascular syndromes of cervical osteochondrosis; Group III, of those with systemic scleroderma) which involved a series of vegetative tests (measurement of the heart rate, the cold test, Aschner's test, determination of autonomic provision of intellectual and other types of activity), authors draw a conclusion about the presence of a close correlation between RP and the psychovegetative syndrome and dysfunction of nonspecific systems of the brain. On the other hand there are differences in the psychophysiological organization of the idiopathic form of RP vs. Raynaud's syndrome, which should be taken into account in the treatment of angiotrophopathic disturbances.

November 1986
Informative signs for classification of disorders of consciousness were distinguished on the basis of clinico-physiological comparisons. Coma is characterized by failure of attempts to wake the patient, deep coma by muscular atonia, and protective inhibition coma by bilateral mydriasis. Opening of the eyes in response to a sound or pain is characteristic for the apallic syndrome, carrying out of instructions for deep stunning, answering questions for stunning.

Zh Nevropatol Psikhiatr Im S S Korsakova
January 1985
The results obtained in a study of 100 patients formed the basis for major differential diagnostic criteria of psychogenic tics in children. Polygraphic examination of the sleep-wakefulness cycle revealed dysfunctions in the nonspecific cerebral systems in the form of hyperfunction of the activating and insufficiency of the inhibitory apparatuses which were expressed in all functional states in the EEG, motor and vegetative spheres. These changes are considered to be pathogenetically important in view of their connection with the most significant clinical characteristics of the disease.
