Behavioural genetic technique (model fitting) was used to study the genetic and environmental contributions to individual variability of power of the alpha-frequency band and its components (alpha 1 = 7.5-9.0 Hz; alpha 2 = 9.5-11.0 Hz; alpha 3 = 11.5-13.0 Hz) in different brain areas. 26 pairs of monozygotic and 22 pairs of dizygotic twins aged 6-8 years participated in EEG study. EEG was recorded from the frontal (F3, F4), central (C3, C4), temporal (T3, T4), parietal (P3, P4), and occipital (O1, O2) areas. Our study revealed that the nature of different alpha-components was different. It was found that the later in the ontogenesis a component of the alpha-frequency band became dominant in the EEG the less genetic factors contribute into the family resemblance.
采用行为遗传学技术（模型拟合）研究遗传和环境因素对不同脑区α频段及其成分（α1 = 7.5 - 9.0Hz；α2 = 9.5 - 11.0Hz；α3 = 11.5 - 13.0Hz）个体差异的影响。26对6 - 8岁的同卵双胞胎和22对异卵双胞胎参与了脑电图研究。脑电图记录于额叶（F3、F4）、中央区（C3、C4）、颞叶（T3、T4）、顶叶（P3、P4）和枕叶（O1、O2）区域。我们的研究表明，不同α成分的性质不同。研究发现，α频段的某个成分在个体发育过程中越晚在脑电图中占主导地位，遗传因素对家族相似性的贡献就越小。
