EEG was recorded in children aged 8.5-9.5 years in the rest («O»), during presentation to remember of onscreen monochrome conditionally nonverbal picture («P»), and while holding a picture in memory («Y») . We have evaluated the relative spectral power of 0-, а-2-, 5- and в-band of total EEG in the right and left hemispheres. It was shown directional reduction of RSP а-2 in boys from the state of «O» to state «P», from «P» to «Y» in the right and left hemispheres. In the left hemisphere in girls the RSP а-2 was decreased from the state of «O» to «P», and then increase from «P» to «Y». The boys RSP 0 increases from the state of «O» to «P» and from «P» to «Y». In girls, the RSP 0 increases from «O» to «P», and then - decreases from «P» to the «Y» in the right and left hemisphere. The boys RSP в increases from the state of «O» to «P», and then - decreases from «P» to «Y». In girls, significant trends of the RSP в were not revealed in the right and in the left hemisphere. The boys RSP 5 increases from the state of «O» to a state of «P» and then reduced to a state of «Y» in both hemispheres, and in girls - the RSP 5 decreases from «O» to «P» and then restored to the state «Y» in both hemispheres.
