The study of the self-similar nature of human neuromagnetic responses when exposed to flickering light stimuli

In this work, we investigate the self-similar properties of the neuromagnetic responses of healthy subjects and a patient with photosensitive epilepsy in response to flickering light stimuli of different color combinations (red-blue, red-green, blue-green). The calculation of the fractality index for different areas of the human cerebral cortex is performed by the modified Higuchi method. Areas were identified in which spatio-temporal scaling is manifested to the greatest extent in photosensitive epilepsy. In addition, changes in the fractal structure of magnetoencephalograms of healthy subjects were found after exposure to flickering light stimuli. In the future, the use of machine learning methods for recognizing the images of topographic maps of the obtained numerical indicators will contribute to the search for new diagnostic criteria for neurological diseases and mental disorders (various forms of epilepsy, multiple sclerosis, obsessive-compulsive disorders). The results obtained will be useful for specialists working in the field of neurosciences, physics of complex systems and cognitive psychology.
