Analysis of Effect of Audiovisual Stimulation on Parameters of Encephalogram and Rate of Pulsation Wave Propagation in Humans

  • Published:
Biomedical Engineering Aims and scope

The effect of visual-audio stimulation on the parameters of electroencephalogram (EEG) and the pulsation wave propagation rate (PWPR) in humans was analyzed. The effect of rhythmic audiovisual stimulation (AVS) on the parameters of EEG was also tested. In both cases the effect on EEG was higher than the individual effects from sound and color stimuli. During analysis of the influence of rhythmic visual stimulation and AVS on EEG parameters, frequency peaks corresponding to various color stimuli were revealed in EEG. It was established that most significant changes in brain activity were caused by color stimuli with the highest saturation coefficient and by audio stimuli of maximal sound intensity. The frequency range of maximal deviation from background EEG during rhythmic AVS was observed. Maximal RPWP value was observed in the case of visual-audio stimulation.
