title: [Differences of activations in visual and associative zones during figurative and verbal activity].
abstract: The study considers correlates of figurative and verbal tasks performance during attention paid to visual stimuli. There are 34 subjects (20 female, mean age 21, 2.5 [SD]) took parts in the study. During subjects performance of the task, there was carried out EEG registration from 19 sites according to 10-20%. Performance of the figurative creative task in comparison with control non-creative task of the same modality was accompanied by activation of occipital and parietal zones of the cerebral cortex (decrease of EEG spectral power in alpha 1 (7.5-9.5 Hz) and alpha2 (10-12.5 Hz) frequency bands was observed) whereas performance of a verbal creative task in the similar test-control comparison was accompanied by decrease of activation in occipital zones (revealed through increase of EEG spectral in alphal and alpha2 frequency bands). As visual stimuli were shown during the whole time of the creative and control tasks fulfilment was made an assumption observed distinction can be connected with redistribution of attention focus at various types of creative activity (figurative or verbal).
