怒り刺激に対する血液循環応答と心拍変動解析

摘要

There is autonomic specificity in emotion. Objective evaluation for emotion using physiological parameters has some possibilities of applications to the creation of comfortable environment, emotional movies or advertisements, to the human interface of the machine that obeys emotions, and to an understanding of emotions of the patients who cannot speak. As anger correlates with the stress, the psychosomatic disease and coronary heart disease, an understanding of the physiological features is important in medicine. But, the responses of blood circulation and autonomic nerve activities in anger, which is often felt in daily life, are not clear. Therefore, the measurement of blood circulation in anger was introduced, and the autonomic nerve activities and the minimum value of the cross-correlation coefficients between RSA and the respiratory wave (pmin), which could associate with the autonomic nerve activity, were evaluated. Further, the correlation of the physiological parameters with subjective evaluation was investigated. Anger increased SBP/DBP and maintained their levels for a while. These reasons were estimated by the analysis of Pulse Wave Amplitude to the effects of sympathetic a-adrenergic vasoconstriction of the arteriole and slow metabolism of noradrenaline and adrenaline which must be elicited by anger. Anger did not change HR, but increased double product and maintained its level for a while. On the other hand, the correlation of pmin with subjective evaluation was obtained. Therefore, pmin is an effective index to objective evaluation for anger strength.
