Abstract:The article presents the results of a study designed to assess the anxiety and an analysis of its individual components in 104 elderly women. Summary of the data obtained shows that women between ages 55-64 years have higher anxiety in comparison with older women (65-74 years of age). This is due to emotional difficulties associated with a person's transition to old age. The anxiety is expressed as emotional discomfort indicators and in anxious assessment of near-term perspective. High indication of asthenic symptoms were present in both age groups, which is likely to be associated not only with the manifestation of anxiety but also with a separate state characterizing the elderly.UDC Classification: 612.67, 159.9.072.43, DOI: http://dx

In the article, there have been given results of a study of the brain bioelectrical activity in primary school children in periods of increasing, maximum, decreasing and minimum day length. Amplitude and frequency dynamics of basic EEG rhythms has been described, and their interrelation with periods of natural illumination has been determined. It has been detected that adaptive tuning of the brain bioelectrical activity occurred in contrasting seasons. During the period of increasing day length, increasing activity of all EEG rhythms was observed, while in the period of decreasing day length, delta- and theta- activity in all regions of the brain dominated. It has been proved that the detected dynamics of amplitude and spectral-frequency EEG parameters in the northern schoolchildren aged 9-10 years was not caused by age-related changes. Periods of maximum and minimum day length can be considered more favorable for the brain functioning and development of higher mental functions of children.
