EEG dynamics during the listening to the rock music with modified frequency structure
Investigation of the emotional influence of audio stimuli on the human is relevant and popular today because the music in everyday life has a lasting impact on the psycho-physiological state. The aim of the study was to investigate neurodynamics of human brain during listening to the sounds (white noise and sound of birds) and two variants of rock music (complete frequency range and cutting frequency range (60, 150, 400 Hz). 20 healthy volunteers (women and men) - students aged 18 to 22 years with no prior musical education participated in this study. We estimated the spectral power density (SP) of all frequencies from 0.2 to 35 Hz. The results demonstrated that the changes of SP in theta- and beta-bands during listening to the sounds and rock music are related to emotional and cognitive processes. During listening to the rock-music in both variants we observed the different lateralization: left temporal, parietal and occipital zones (the native rock music) and right frontal, temporal and parietal zones (the rock music with reduced frequency range). This allows us to conclude that during listening to the music take place analytic cognitive process and/or emotion activating componente observed the different lateralization: left temporal, parietal and occipital zones (the native rock music) and right frontal, temporal and parietal zones (the rock music with reduced frequency range). This allows us to conclude that during listening to the music take place analytic cognitive process and/or emotion activating component
