Вікові особливості швидкості центральної обробки інформації у осіб з різним рівнем функціональної рухливості нервових процесів

The dynamics of the speed formation of the central information processing (CIP) and its connection with functional mobility of nervous processes (FMNP) was investigated among the persons aged 7-20. The indexes of CIP and FMNP among the children, teenagers and youngsters were found to increase gradually and to reach maximum development at the age of 19-20. Statistically significant differences of the CIP speed were found in all age groups of the investigated persons with different levels of FNMP. The persons with high level of FNMP were characterized with reliably high indexes of CIP compared with subjects with the low level of investigated typological properties of high nervous activity (HNA). The correlation proved the reliable relationships between investigated variables. The general age-related conformities in forming CIP and FMNP were established favoring the genetically determined program for development of these nervous system properties. There is a reason to confirm that the index of CIP speed characterizes individual features of information processing and reflects the typological properties of HNA side by side with FMNP.

Physiological prerequisites for successful interaction between child and computer

The following specific psychophysiological functions, important for computer work, were identified in children aged five to six years: the functional mobility of nervous processes; the accuracy of hand kinesthesia; the functional state of the accommodative system of the eye; mental capacity, volume and concentration; and short-term memory function. A considerable number of preschoolers (47%) proved to have an insufficient level of development of body functions, necessary for successful interaction with a computer.

The influence of artificial mountain climate on the functional state of upper regions of the central nervous system in man

The study included 97 patients with vegetative vascular dystonia and chronic non-specific pulmonary diseases exposed to artificial high-altitude climate in an Orotron climatic chamber during 2 weeks. Atmospheric conditions maintained in the chamber had the following parameters: partial pressure of oxygen - 147-160 gPa, relative humidity - 60-70%, air temperature - 16-18 oC, light aeroion content - up to 6000 cub.cm. It was shown that the exposure to artificial mountain climatic conditions enhanced functional mobility of nervous processes and decreased the length of the sensorimotor reactions of the patients. Individual differences in the change of parameters being measured depended on the degree of initial functional flexibility of nervous processes.

Reactions of the autonomic nervous system of students with different characteristics of higher nervous activity in the situation of examination stress

The influence of examination stress on the reactions of the autonomic nervous system in students with different levels of functional mobility of nervous processes (FMNP) was studied. More intense functioning of the cardiovascular system and the strain of all regulatory mechanisms during examination stress were characteristic of individuals with low FMNP, whereas students with high FMNP values were characterized by a weaker strain of the mechanisms of cardiac rhythm regulation, more economical activity of the cardiovascular system, and better performance on the examinations. The activation of humoral, metabolic, and sympathetic effects was observed in all the subjects under examination stress, along with decreased parasympathetic effects on the cardiac rhythm.

Changes in human conditioned reflexes induced by carbon monoxide and by vibration

Observations were made on the conditioned reflex activity of 36 subjects during exposure to high CO concentrations and intense vibration. The result was a uniform stabilization of the latent period of the conditioned reflexes. The condition induced is regarded as a special state of the cerebral cortex in which the functional mobility of nervous processes is reduced.
