Investigation of the Music's Effect on Human Brain Activity Using Electrical Capacitance Volume Tomography Brain Scanner and Electroencephalo-Graphy

In this study, ECVT brain scanner is used to measure electrical signals generated by the activity of the human brain to the audio response. The basic principle of ECVT is the permittivity distribution mapping of objects based on data measured capacitance. Data capacitance is a response to changes in the permittivity distribution in the brain which are affected by brain electrical potential. ECVT system consists of shaped-helmet sensors, 32-channel data acquisition system, and a computer for image reconstruction process and display the results of scanning. Based on the experimental results, the electrical signals from the electrode capacitance shows a clear distinction, when subjects listened to classical, pop and rock music. Furthermore, it also showed that the brain electrical signal of right hemisphere is higher than the left hemisphere when listening to music. These results from ECVT are consistent with the results of measurement using EEG. Analysis of the reconstructed image show that there is an increase in brain activity in the temporal lobe when listening to rock music when compared to the classical music. ECVT brain scanners can be used to observe the electrical activity of the brain that includes auditory activity.
