BACKGROUND: The aim of the research was to reveal the individual features of synchronization of neuronal networks in people with different level of self-regulation of the functional state of the CNS.
METHODS: The research sample included 38 athletes, meditation practitioners, and people with increased anxiety aged 20-40. We analyzed the baseline EEG record with opened eyes for 30-60 minutes, test with eyes closed for 10-30 minutes, and mental calculation test. EEG sampling rate was 250 Hz.
RESULTS: It was possible to distinguish the areas (epochs of analysis) of synchronization at one dominant frequency of the alpha rhythm in the group of leads individually for each participant. The analysis of synchronized leads allowed us to find four different individual patterns. The regular synchronization of fronto-centro-temporal leads was typical of athletes and meditators. People with increased anxiety levels had synchronization of centro-occipital and temporal leads accompanied by asymmetry between left and right hemispheric leads.
CONCLUSIONS: The obtained data make it possible to determine the current type of individual EEF pattern, predict the capacity of regulation of one’s functional state, and be used as a scientific basis of developing means for correction of the functional state of the nervous system and for training of self-regulation skills.
