The activity of the brain cortical network during solving tasks

In this paper, we analyze the functional connectivity between changes in the concentration of oxyhemoglobin, deoxyhemoglobin, and total hemoglobin, recorded by various leads of fNIRS from the frontal and parietal cortex. The obtained coefficients characterizing the functional connectivity between a pair of leads were presented in the form of a matrix. We analyzed the changes in functional connectivity during the performance of the subject of simple cognitive tasks associated with spatial perception.
