| Outline of Final Research Achievements |
We have developed the programs offering wide-range acoustic and natural environment sounds to activate the Kansei brain network. This neural network, which projects from the deep brain structure to the prefrontal cortex, plays an important role in controlling behaviors based on emotional reactions such as pleasure and aesthetic appreciation as well as coordinating mind and body functions.
Analysis of the acoustic of our newly developed musical instruments and natural sounds reveals that these contain significant quantities of non-stationary, high-frequency components above the human audible range that activate the Kansei brain network. We statistically confirmed the effect of such sounds through experiments on healthy volunteers and psychiatric patients.
Program testing in both educational and medical fields provides a promising perspective for subsequent research efforts.
