[Common and individual in EEG spectral differences while performing verbal and spatial tasks].

[Article in Russian]

Abstract

It is shown previously that types of carried-out spatial-figurative and verbal-logic tasks can be distinguished by means of the trained automatic classifier, using individual for each examinee characteristics of EEG power spectra. Research with application of a subset of the same tasks, but aimed to identify the EEG spectral power group differences has been carried out with 31 participants. Contrast distribution of statistically significant differences on frequency bands qualitatively coincides with ranging of the bands by estimates of efficiency of recognition with the trained classifier, except for a range theta. Alpha bands are most involved. Results of comparison of the general (group) and individual indicators correspond to ideas of more significant involvement of mechanisms of semantic memory in the solution of verbal tasks, and also point to possible differences in balance of internal and external attention at realization of verbal-logic and spatial-figurative activity.
