[INFLUENCE OF SOCIAL FACTORS ON PERSONAL SOCIAL AND PSYCHOLOGICAL ADAPTATION AND FUNCTIONAL STATE OF THE CNS IN NORTHERN CHILDREN].

The results of the socio-psychological and psycho-physiological study of children and adolescents rural secondary school in a remote area of the Arkhangelsk region were studied. It was found that the poor situation of children in families at social risk leads to a decrease in their school performance, motivation to succeed and, in some cases, to reduce their personal social and psychological adaptation. However, in general, the level of personal social and psychological adaptation in the majority of surveyed students is high enough.

Comparative analysis of the EEG in babies in the first month of life with gestation periods of 30-42 weeks.

The aim of the present work was to compare measures of the power spectra, indexes, and coherence of the EEG in term and preterm infants in the first month of life. Six groups of children were investigated, born at 1) 30-32, 2) 33-34, 3) 35-36, 4) 37-38, 5) 39-40, and 6) 41-42 weeks of gestation; there were 10 in each group. The power of the delta frequencies was maximal in group 5.

[Comparative analysis of the infant EEG at gestation term 30-42 weeks].

The research involved comparison of characteristics of the power spectrum, index, coherence of the EEG at preterm and full-term infants of the first month of life. 6 groups of children are surveyed: (1) 30-32, (2) 33-34, (3) 35-36, (4) 37-38, (5) 39-40, (6) 41-42 weeks of gestation; each group consisted of 10 children. Capacity of delta frequencies was high in the 5th group.

[Characteristics of the EEG power and coherent structure of term and premature children during the first postnatal year].

Objective of the study involved characteristics of the spectre of the EEG power and coherent structure in children of different degree of maturity in the first month of their postnatal development. 32 children were divided into three groups: 1) 38-41 weeks (11 children); 2) 34-36 weeks (12 children); 3) 30-33 weeks (9 children). At the moment of the study the children's chronological age was as follows: in the 1st and 2nd groups--19 +/- 1, in the 3rd group--30 +/- 4 days.

[Changes in spectral coherent characteristics of EEG in the early postpartum period in mothers with anxious and depressed mood].

Postpartum EEG spectral and coherence characteristics were estimated in mothers with or without postpartum depressions. In mothers without affective disorders the power of oscillations in the delta, theta, and alpha 1 frequency bands was increased as compared to controls. Intrahemispheric EEG coherence between the left frontal and adjacent derivations in the delta and theta bands and interhemispheric coherence in the central areas was increased and decreased over the remaining cortical surface.
