Relative SMR wave power spectra analysisofvisual arts majorsand non-majors

The change of SMR (sensorimotor rhythm) power spectrum of human’s EEG for visual stimuli is analyzed in this paper. The subjects are consists of two groups of twenties’ university students, one is majoring in visual arts and the other is non-majors. Two opposite visual stimuli of abstract paintings (Mondrian’s and Kandinsky’s) are provided to the two groups. EEG (Electroencephalogram) is measured using a standard equipment manufactured by Laxtha Inc. for 6 positions of the frontal and occipital lobes. The power spectrum of SMR wave for each position is analyzed and it is used to compare between the two groups. It is found that there are obvious difference in brain activity in the viewpoint of SMR power spectrum between the two groups. Major group shows higher brain activity at the frontal lobe for the artistic visual stimuli compared to non-major group and it can be thought as the result of their higher brain activity by analyzing the intention of the artists.
