摘要

The focal riddle for physicists and neuroscientists consists in disclosing the way microscopic scale neural interactions pilot the formation of the different activities revealed (at a macroscopic scale) by EEG and MEG equipments. In the current paper we estimate the degree of the interactions between the remote regions of the brain, based on the wavelet analysis of EEG signals, recorded from these brain areas. With the help of the proposed approach we analyze the neural interactions, associated with cognitive processes, taken place in human's brain during the perception of visual stimuli. We show that neurons in the remote regions of brain interact with the different degree of intensity in the generation of different rhythms. In particular during the perception of visual stimuli strong interaction has been observed in β - frequency band while strong interaction in a - frequency band has been observed in resting state.
