[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. Latency of P300-wave and reaction time were calculated. It is shown that time reaction in stochastic, probabilistic and deterministic environmental conditions increase with age. The search activity is random, that leads to restriction of adaptive capacity of the organism. The increase in the number of errors in older women indicates a lack of mobility of mental processes. According to the temporal characteristics of the wave P300 it has been revealed that latent time increases with age mainly in the posterior-temporal, parieto-occipital and occipital areas of the right hemisphere. The inter-hemispheric asymmetry with a predominance of the left hemisphere was noted. The obtained age-related changes are most likely due to sensory deficiency, reduced neurotransmission and displacement of the locus of cognitive activity in the left hemisphere.
