| Outline of Final Research Achievements |
We aim to explore expression mechanism of the hypersonic effect, which is induced by sounds containing rich amount of inaudible high-frequency component of sounds above human audible range. We found that enrichment of sound environment significantly prolonged natural life span of mice. We also found that different sound environment containing human inaudible high-frequency component significantly affected the behaviors as well as corticosterone level of mice, which utilize ultrasound vocalization for communication. We explored the activation of reward-generating neuronal system in subjects under possession trances in Balinese ritual ceremony induced by sensory information including sounds containing inaudible high-frequency component using live recording of spontaneous EEG.
