This study is an attempt to analyze the relationships between EEG and dermatoglyphic patterns (DP) in 6-8 years girls. EEG-mapping was carried out in 80 healthy girls with different types of DP in 6 frequency band: delta, theta, alpha-1, alpha-2, alpha-3 and beta. Certain connection of the palmar and finger patterns with the EEG characteristics was revealed. The most pronounced differences were observed between subgroups with prevalence (8 and more) or absence of whorls on their hands fingertips, and between groups with presence or absence of certain pattern (whorl, loop or vestige) on thenar/interdigital 1 area (Th/1). Significant (p<0.05) increase of spectral density in alpha-2 and alpha-3 bands in children with whorls on hand fingertips were revealed in the first case. EEG of children with Th/1 pattern differed from the group without such pattern by increased spectral density in alpha-2, alpha-3 and beta bands. The new data obtained support the genetic determination of the EEG.
本研究旨在分析6至8岁女童脑电图（EEG）与皮纹模式（DP）之间的关系。对80名具有不同类型皮纹模式的健康女童进行了脑电地形图检查，检查频段为6个：δ波、θ波、α1波、α2波、α3波和β波。研究发现手掌和手指模式与脑电图特征之间存在一定联系。在指尖有8个及以上螺形纹或无螺形纹的亚组之间，以及在大鱼际/第1指间区（Th/1）有特定模式（螺形纹、箕形纹或痕迹）或无特定模式的组之间，观察到了最明显的差异。在第一种情况下，发现指尖有螺形纹的儿童在α2和α3频段的频谱密度显著（p<0.05）增加。有Th/1模式的儿童脑电图与无此模式的组相比，α2、α3和β频段的频谱密度增加。获得的新数据支持脑电图的遗传决定因素。
