The study of correlation and spectral characteristics of human brain activity while performing cognitive tasks

In this paper, within the framework of Memory Function Formalism, one of the analysis methods in statistical physics, we study bioelectric activity features of the brain for two groups of people. The first group consisted of 10 artists with a Master of Arts degree, the second was represented by 10 people without any art education. The subjects performed the tasks of visual perception and mental image. As a result of autocorrelation analysis, we identify regions of the cerebral cortex in the activity of which the most significant differences were manifested. We observe features of electroencephalogram spectral parameters for two groups of subjects. As a result, we show that the use of statistical analysis methods allows detecting the difference in the cognitive abilities of people when performing various cognitive tasks.
