Dynamics of the functional organization of brain cortex in subjects with different level of creativity at the stages of solving nonverbal creative task

Abstract

Event Abstract Back to Event Dynamics of the functional organization of brain cortex in subjects with different level of creativity at the stages of solving nonverbal creative task Liudmila A. Dikaya1* and Pavel N. Ermakov1 1 Southern Federal University, Russia The objective of our research is to study features of the functional organization of brain cortex depending on the subjects’ creativity level at the stages of solving nonverbal creative task. The participants were 72 university students at the age of 18-22 divided into two groups – with an average (38 participants) and high (34 participants) level of creativity. They were asked to perform nonverbal creative tasks (to draw the original picture, to compose music). EEG correlates were recorded at a resting state and at three stages of creative problem solving - at a preparation stage, at insight stage and at a check stage. Coherence function of the EEG in 6 frequency bands (from 4 to 35 Hz) was analyzed. For statistical analysis we used 4-way ANOVA (Task (art, musical) × Stage of Creative Process × Frequency Band × Type of EEG coherence) and post hoc analysis to compare the features of the functional organization of brain cortex in average-level creative and high-level creative experiment participants at different stages of solving nonverbal creative task. Results: We obtained significant increase of EEG coherence during insight at low frequency bands and at the stages of preparation and check at high frequency bands compared to previous stages in high creative individuals (p < 0.05). At insight stage at beta-2 band the independent and parallel functioning of brain hemispheres is revealed in these participants. Conclusion: High functional specialization of the brain to solving nonverbal creative task is characteristic of high creative subjects. The dynamics model of the functional brain system during the nonverbal creative process includes 3 levels: 1) Modulation level, 2) Specific creative cognitive level, and 3) Specific level depending on the subjects’ creativity level.
