[Characteristic of the behavioral response and cognitive evoked potentials at 60-74 aged women.].

The article presents the results of the study of the characteristics of behavioral response and cognitive visual event related potentials in 90 elderly women. To analyze a behavioral reaction the computer complex KPFC-99 «PSYCHOMAT», which includes the computer test system Binatest (Moscow) was used. The event related potentials were registered for all participants with using of 128-channel system GES-300.

[Studies of the dc-potential of the brain level distribution in elderly women with high anxiety.].

The article presents the results of studies of the direct current (DC) potential of the brain level distribution in elderly women with high anxiety. Analysis of the DC-potential of the brain level distribution was held by mapping obtained by measuring the monopolar values of the DC-potential of the brain and calculating deviations in each of the leads from the average records which were registrated in all areas of the head. The results of the study indicate an increase in the background level of the DC-potential in most parts of the brain and the peculiarity of its distribution in elderly women with a high level of anxiety.

[An aging brain: morphofunctional aspects].

A review of main results in the field that are relevant for understanding of the clinical pathology developed in old age is presented. The authors focus attention on the characteristics of atrophic processes and their severity in different brain structures including cognitive impairment (memory etc). Correlations between structural changes in brain tissues and neurochemical and bioelectrical processes in the CNS are discussed.

[The DC-Potential of the Brain in Older Women Circumpolar Region].

DC-potential of the brain was performed in 97 women 55-74 years old living in the circumpolar region. Study and analysis of the distribution level DC-potential brain mapping was carried out by the measured values of monopolar constant potentials. The resulting distribution characteristics DC-potential compared with the average values for the corresponding normative age period.

[The DC-potential of the brain in older women with postural instability].

The article presents the results of studies of the DC-potential of the brain level distribution in elderly women with postural instability. Analysis of the DC-potential of the brain level distribution was held by mapping obtained by measuring the monopolar values of the DC-potential of the brain and calculating deviations in each of the leads from the average records which were registered in all areas of the head. It is established that elderly women with postural instability DC-potential of the brain level distribution are characterized by increasing in background values and rigid structure of the interaction between brain regions.

[Behavioral response of older women in a stochastic environment].

The article presents the results of studies of the behavioral response in 63 elderly women. With the help of a computer complex for psychophysiological studies KPFK-99 "Binatest" we estimated figures of restructuring strategies of decision making in a stochastic environment. The leading psychophysiological mechanisms of behavioral response of older women in a stochastic environment are presented as a high-speed component of decision-making process, and search activity as a dynamic component of motivational orientation dominates over the informational component of the decision-making on the temporary costs.
