The influence of professional art preparation on the features of the formation of brain cortex’s functional links in the performance of imaginative creative activity

Abstract

The article gives an analysis of modern ideas about the brain mechanisms of creativity. The authors note the diversity and inconsistency of the results of modern research of brain correlates of human creative activity. Relevance of the study of the dynamics of brain functional organization at different stages of the artistic creative process in humans, depending on the level of training and productivity of imaginative creative activity is proved.
The technique and the procedure of empirical research are described. 60 students aged 18–23 took part in the study. For modeling of creative activity the technique of monotype was used. Peculiarities of brain cortex’s functional connections during the imaginative creative activity were investigated by EEG method. Statistical comparative post hoc-analysis was carried out for representatives of four groups of research participants: not artists with low level of productivity (10 people); not artists with medium level of productivity (20); artists with medium level of productivity (12) and artists with a high level of productivity (18 people).
On the basis of the comparative analysis it is confidently shown that a high level of professional training of artists is associated with the active formation of intra- and interhemispheric short functional connections of the brain cortex in the high frequency bands (alpha2, beta) that maximizes the efficiency of creative problem solving, as well as contributes to the speed, ease and productivity of image creation.
It is concluded that the level of productivity of imaginative creative activity in artists effects the optimal processing of imaginative information. Strong long intrahemispheric functional connections in the low frequency bands (delta band) are revealed in research participants with high levels of productivity
