Source-level analysis of brain activity in the process of learning and retrieving new information

In this paper, we discovered the increase in EEG power in the theta frequency range in the occipital cortex during a visual analysis of new information and the power decrease in the alpha range in the temporal lobe during retaining information. The revealed increase in theta power correlates with the response time and errors rate. The alpha power correlates with response time. Summarizing the above, the detected cluster of theta-activity during information perception may reflect the increased concentration of attention.
