Quantification of mental healing and verification of the pain relaxation effect of a disease based on cerebral function analysis

通过对脑氧浓度水平和反映脑神经系统激活水平的活体信号的研究，分析了音乐疗法和芳香疗法对人体精神状态的影响。在音乐呈现的分析中，我们提出了一种基于氧浓度的绝对值和波动来量化大脑功能激活水平的方法，并验证了音乐治疗的效果。在芳香疗法的分析中，我们提出了一种可以分析精神状态变化的方法，该方法基于可以量化自主神经激活水平的活体信号，并分析了香水供应的效果。在这些调查中，除了在香川大学的实验室进行实验外，我们还在香川县的老年护理之家进行了实验。

We investigated the level of cerebral-oxygen concentration and the living body signals that reflect the activation level of autonomic-nervous system, and analyzed the effectiveness of musical therapy and supplying aroma on the mental state of human body. In the analysis of music presentation, we proposed a methodology that can quantify the activation level of a cerebral function based on the absolute value and the fluctuation of oxygen concentration, and we verified the effect of musical therapy. In the analysis of aroma therapy, we proposed a methodology that can analyze changes of the mental state, based on the living body signal which can quantify the activation level of autonomic nerves, and analyzed the effect of perfume supply. In these investigations, we conducted the experiment in the elderly-nursing home in Kagawa Prefecture besides the experiment in a laboratory of Kagawa university.
