© 2021, The Author(s), under exclusive license to Springer Nature Switzerland AG.We simulated radial traveling waves of local currents on the folded surface of the human cerebral cortex. The magnetic fields on the surface of the head were calculated by individual MRI. Model MEGs were compared with experimental data using two-dimensional correlation. The maximum values of correlation coefficients were determined for traveling wave velocities of 0.2 m/s with epicenters in the occipital lobes of the brain, including V1 and V2. In these cases, a jump in the levels of maximum correlations in time and space took place. At a velocity of 6 m/s, the maximum values were lower, and the change in the level of correlations was smoothed out. The results of the study show the advantage of the intra-cortical hypothesis of the brain traveling waves.
