[The Psychomat computer complex for psychophysiologic studies].

The authors analyze the principles of the design of a computed psychophysiological system for universal uses. Show the effectiveness of the use of computed technology as a combination of universal computation and control potentialities of a personal computer equipped with problem-oriented specialized facilities of stimuli presentation and detection of the test subject's reactions. Define the hardware and software configuration of the microcomputer psychophysiological system "Psychomat". Describe its functional possibilities and the basic medico-technical characteristics. Review organizational issues of the maintenance of its full-scale production.

[Rhythmotest, Mnemotest, Binatest--a family of microprocessors for studying higher nervous activity in man].

The design of outfits for analysis and parametrization of the fundamental mechanisms and functions of the higher nervous activity (HNA) is one of the efficient approaches to solving problems of medicine equipment with technical facilities of deriving objective data on the CNS status of man. With this purpose in view, "Rhythmotest", "Mnemotest" and "Binatest" outfits unified in terms of methodology and engineering have been devised. Each of the outfits is a functional combined system that permits analyzing a definite mechanism of the HNA as a totality of its basic manifestations with the aid of different methods. "Rhythmotest" makes it possible to examine the mechanisms of assimilation and reproduction of rhythmic irritants, "Mnemotest" the mechanisms of memory and visual perception, and "Binatest" the mechanisms of making a decision. The outfits may be widely used in solving research and applied problems.

[Correlation of the parameters of central and regional hemodynamics of the eye in patients with open-angle glaucoma].

Studies of this correlation have revealed correlation between stroke and minute blood volumes in reference subjects and in patients with open-angle glaucoma with the rheographic coefficient. No correlation at Stages II-IV glaucoma indicates a decompensation of ocular hemodynamics regulation mechanisms. Hemodynamic disorders should be corrected already during the first stage of the disease to prevent the disease progress to later stages.

[Use of the PFK-01 psychophysiologic unit in the diagnosis of alcoholic patients].

Alcoholic patients were tested on production of short time intervals by means of psychophysiological computer-controlled unit PFK-01 after the dedicated software was completed. Subjective time rate was related to the emotional state of patients. A tendency towards hypoproduction, i.e. towards acceleration of subjective time rate, was associated with the state of anxiety.

[Set of devices for psychophysiological research].

For more efficient practical application of psychophysiological examination methods in the network of therapeutic-prophylactic and polyclinical establishments a set of instruments-II phi K-01 has been developed. It was produced on the basis of a programmed key-board computer and permits automatic patient examination with processing the data by 12 psychophysiological methods.

[Computerized instrumental tools for psychophysiological studies of normal higher nervous activity and in pathology].

The paper considers the theoretical bases of design and examples of practical use of specialized computerized instrumental tools for psychophysiological studies of higher nervous activity in man. A number of principles in the design of medical devices and units for psychophysiological examinations have been defined by analysing some P.K. Anokhin's concepts and from the author's own experience in designing and employing psychophysiological equipment, which is reflected in the concept of psycho-engineering. The paper provides the most typical examples of some generations of the proposed scientifically based devices and complexes for psychophysiological examinations, such as a KPFK computerized unit for psychophysiological examinations, a specialized personal computer terminal for determining the characteristics of sensomotor coordination and tremor, a specialized physicomedical terminal of a personal computer for evaluating the steadiness of the gravity center of a person's position, Rhythmo-Mnemo-Binatest automatic microprocessor apparatuses for assessing the characteristics of human higher nervous activity in health and in disease.

[Standardization of of instrumental tools for psychophysiological examinations].

The paper presents an approach to standardizing the methodical and technical aids used for qualitative and quantitative instrumental assessment of some human higher cortical functions in health and in disease. The formulated approach and some experience in developing and using instrumental tools to examine higher nervous performance enable one to define the basic characteristics and parameters to be standardized.

[Instrumental studies of motor function using "Stabilotest" and "Ataxitest" devices in preschool children].

The paper describes devices used to examine motor functions in preschool children, methods of examinations and presents their results. Instrumental indices of the development of large and small motility in preschool children and objective criteria for the efficiency of stimulant therapy are proposed. It is shown that the devices for examination of motor functions may be successfully used to train coordination functions of a child and to correct static motor and ocular motor performance.

[A new approach to assessment of the impairment of higher cortical function in psychoneurological diseases in children and adolescents by instrumental computer-assisted methods].

The authors discuss the possibility and efficacy of instrumental methods of psychophysiological examinations: automated devices Ritmotest, Mnemotest, and Binatest for assessing the disorders of the higher cortical functions in children with psychoneurological diseases. The main protocols and parameters for examination of children aged 7 to 15 years with various diseases are offered, test performance by children of different age shown, and score values fit for practical use of the above devices obtained.

[Use of an experimental space-time prediction model to design instruments for evaluation of higher nervous activity in man].

While examining the basic mechanisms responsible for the performance of the central nervous system (CNS), of interest are the situations in which the behaviour caused by these mechanisms and independent of education levels, habits, and occupation is shown to the highest extent. The paper presents an example of constructing and testing an experimental model which may assess different manifestations of CNS functions. The use of the model as textual examination procedures provides an insight into the higher nervous performance.
