Abstract

There were analyzed the parameters of spectral density in 1 Hz subranges of EEC (between 3 and 12 Hz) in schoolchildren (1-4 classes, 7-11 years old). EEC was registered when Ss were calculating summation tasks. During calculation there were found desynchronization of theta- and alpha-rhythms, relative increasing of input of low band-width frequency component (4-5 Hz) in theta-diapason and high frequency (10-12 Hz) in alphadiapason.
