[Electroencephalographic approach to lateralization in children].
Electroencephalograms were recorded in 76 normal children between 10-12 years of age and several parameters were calculated from the results of spectral analysis. Sections of recordings which were free of artefacts, taken under different conditions (eyes open, eyes closed and during tests of mental arithmetic and vocabulary with the eyes closed were analysed. In these normal children, there was significant asymmetry of the alpha 1, beta 1, theta rhythms, and related parameters at rest, but the asymmetry was not necessarily found to correlate with the laterality of hand, eye, foot or all three. Vocabulary, and to a greater extent arithmetic significantly decreased alpha rhythms. Arithmetic affected both hemispheres equally but vocabulary depressed the alpha rhythms more obviously on the left.
