The Study of Correlations of Neuromagnetic Signals in Response to Flickering Light Stimuli Using Flicker-Noise Spectroscopy

In this paper, we demonstrate the capabilities of the flicker-noise spectroscopy method in the study of cross-correlations and effects of frequency-phase synchronization in biomedical data dynamics of complex living systems. The results of the cross-correlation analysis of healthy subjects magnetoencephalograms in response to the effects of different color combinations of flickering light stimuli (red-blue, blue-green, red-green) were presented. We determine the features of bioelectric activity and different areas of the cerebral cortex interaction, as well establish changes in the 3D structure of two-parameter cross-correlators when exposed to different light combinations, taking into account the high individuality of the studied signals. The study of the light effect on changes in the bioelectric activity of the human cerebral cortex individual areas is interesting in terms of studying cognitive and sensory processes, for example, learning ability and memory performance. The results can be used in biophysics, data sciences, neurophysiology, cognitive psychology, as well as to search the diagnostic criteria of neurological and neurodegenerative diseases (photosensitive epilepsy, Parkinson's disease).
