There are 3 psychological parameters of creativity: fluency, flexibility and originality. These characteristics are important to understand how successfully the process of creativity proceeds. The aim of our study was to investigate the EEG differences in high and low creative subjects during the performance of the tasks for creativity parameters, which were measured separately. Four types of tasks were used: fluency, flexibility, originality and control. Volunteers’ level of creativity (high or low) was measured according to Torrance Creativity Test (verbal battery). Healthy volunteers- 20 high creative и 21 low creative subjects- underwent computer EEG registration while being tested. EEG was recorded from 19 sites (10-20 system) in seven frequency bands. Statistically significance differences of EEG power and coherence in high and low creative subjects for each of creativity parameters tasks versus control were revealed. High creative subjects were characterized by an increase of interhemispheric connections for all types of creative tasks in beta2 and gamma bands, a solitary decreasing of EEG power in alpha, beta, gamma bands for fluency, a general decreasing in alpha2 band for flexibility and a general increasing in gamma band for originality. Low creative subjects were characterized mainly by the rise of intrahemispheric connections in the same frequency for all types of creative tasks in the left hemisphere, and by a general increase of EEG power in beta2 and gamma bands for fluency and flexibility, and a solitary decreasing in alpha1 and gamma bands for originality. Our results indicate that there is a different brain pattern for high and low creative subjects during the performance of creative tasks. Funding: Supported by grant NSh-3318.2010.4.
