In regards to the health maintain on brain, lots of attention is paid. Dementia and recognition symptom are observed if the blood circulation is blocked. At the same time great number of people are suffering from the stressful daily life. In this study, we investigated the effects of bone conduction of music on EEG and ultrasonic vibration on blood circulation. Two kinds of treatments were applied. The first one was music vibration. It was applied from the lateral side of the head. Twelve minutes music, three pieces of Mozart were played using the bone conduction method. The second one was ultrasonic vibration. Ten minutes of ultasonic vibration, every 1.5 seconds and the duration was for 0.2 seconds, was given from the frontal side of the head. Two devices were activated alternately. EEG was recorded before and after the treatments. Thermo-graph and Xenon CT were also taken before and after the treatments. Salivary amylase activity, blood pressure and heart rate were measured, as well. EEG alpha waves were increased by the treatments. Salivary amylase activity was decreased by the treatments. Blood pressure and heart rate were reduced by the treatments. Facial circulation was increased by the treatment according to the thermo-graph. CT showed the blood circulation of the deep region of the brain was also increased by the treatments. It is concluded that the music and ultrasonic vibration were effective on stress and improvement of the blood circulation. [J Physiol Sci. 2008;58 Suppl:S98]
