Analysis of EEG coherence effects of physical loads and rhytnmic auditory stimulation

Objective of the study was to explore the effects of physical loads and auditory stimulation by music of varying rhythm and tempo on the intra-hemispheric EEG coherence rates. It has been established that listening to rhythmic music strengthens the coherence of the cortical bioelectrical activity. For alpha band activity, this effect was more pronounced in the frontal lead, whereas for the theta band - in the occipital lead. The most remarkable effect was observed when listening to music with the RTS of maximum frequency. Physical load with different RTS suppressed coherence, while for alpha activity the effect was more pronounced at low frequencies, for theta activity on the contrary, at high frequencies. Listening to music after exercise helps increase the coherence index (in some cases even higher than background levels).
