Music Evoked Brain Lobe Activation Using Spectral Features form EEG

Physiological research with human brain is being more popular nowadays because it is the center of human nervous system. Music is a popular source of entertainment in modern era which affects differently in specific brain lobes. In this research, an approach has been proposed to identify the music evoked brain lobe activation by using spectral features with different musical stimuli. Music has both positive and negative impact on human brain activity. EEG signals from different subjects are collected for three types of music i.e., mild, pop, rock at different sound level in this work. Music are categorized with their PSD value. The PSD value is 0.21 W/Hz, 0.32 W/Hz and 0.84 W/Hz for mild, pop and rock song respectively. According to the activity, human brain is subdivided in to frontal, central and parietal lobe. From logarithmic band power and PSD value, it is shown that for a preferable sound level (15%-55% volume) central lobe of the brain is more activated for mild song and parietal lobe is activated for both pop and rock song.
