“…The enhancement of posterior interhemispheric coherent connections that was revealed by our research coheres with contemporary views on changes in synchronization of alpha rhythm in modally-specific cortex zones (Farber et al, 2014), and with the opinion that an enhancement of alpha rhythm reflects inhibition of any distracting and interfering information flowing from the visual system (Fink et al, 2011). The increased intensity of frontal interhemispheric connections in artists' brains that was detected in the course of the research at the stage of image creation, can also indicate suppression of cognitive processes that are not directly related to the current tasks.…”

“…Scientists declare that the functional role of alpha1 rhythm is connected with a general state of activation, the actualization of intuitive processes, internal information processing, and inhibition of information that is irrelevant to fulfilling the current task (Behtereva & Nagornova, 2007;Farber, Machinskaja, Kurganskij, & Petrenko, 2014;Fink & Benedek, 2014;Fink, Schwab, & Papousek, 2011).…”

The steadily increasing demand for artistic professions brings to the fore the task of studying the phenomenon of art by researching the unique capacity of the human brain to create works of art in different spheres of creative activity. So far, only a few studies have investigated creativity-related brain activity in representatives of the creative professions. The aim of the empirical research was to study the neurophysiological correlates of artistic image creation by representatives of the artistic professions. The participants were 60 right-handed females aged 23-27, divided into three groups-artists (23 people), actors (17 people), and specialists who do not work in an artistic field (20 people). The mono-typing technique was used to model the creative artistic process. EEG signals were recorded in a resting state, and during four stages of the creation of an artistic image (viewing of monotypes, frustration, image creation, and thinking over the details) from 21 electrodes set on the scalp according to the International 10-20 System. We analyzed EEG coherence for each functional trial at theta (4.00-8.00 Hz), alpha1 (8.00-10.5 Hz), alpha2 (10.5-13.00 Hz), and beta (13.00-35.00 Hz) frequency bands. For statistical analysis, we used MANOVA and post hoc analysis. We found that the neurophysiological correlates of creating an artistic image are different at different stages of the creative process, and have different features for artists and actors. The actors primarily show dominance of right hemisphere activity, while close interaction of the hemispheres distinguishes the brains of the artists. The differences revealed in brain cortex functioning when artists or actors create an artistic image reflect different strategies of imaginative creative work by representatives of these professions.
