EEG MAPPING IN CHILDREN WITH DIFFERENT DERMATOGLYPHIC PATTERNS

This study is an attempt to analyze the relationships between EEG and dermatoglyphic patterns (DP) in 6-8 years girls. EEG-mapping was carri ed out in 80 healthy girls with different types of DP in 6 frequency b and: delta, theta, alpha-1, alpha-2, alpha-3 and beta. Certain connect ion of the palmar and finger patterns with the EEG characteristics was revealed. The most pronounced differences were observed between subgr oups with prevalence (8 and more) or absence of whorls on their hands fingertips, and between groups with presence or absence of certain pat tern (whorl, loop or vestige) on thenar/interdigital 1 area (Th/1). Si gnificant (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 determinat ion of the EEG.
