EEG reactions during creative activity

Abstract

Evoked activity in response to light was recorded in students performing a verbal creative task. The changes in the amplitude of the N200 negative component of evoked potentials were analyzed. The amplitude of the N200 component was significantly increased in the frontal and anterior frontal areas of the left hemisphere, which indicated increased activity in the cortical structures involved in divergent thinking. The amplitude of the N200 component was increased in the temporo-parieto-occipital area of the right hemisphere, which indicated that the posterior associative region of the right hemisphere was also involved in the creative activity. The data obtained suggest that the frontal and temporo-parieto-occipital areas of the cerebral cortex actively participate in the performance of a creative test with distinct elements of complexity.
