| Abstract | 「要旨」心拍数変動や血圧変動の持つ10秒周期(0.1Hz)ゆらぎであるMayer波は, 安静時に明確に現われる. 一方, 強い情動反応が生じた場合などには, 心拍数変動と血圧変動の間の関係性が変化することが考えられる. この予想に基づき, Mayer波帯域における血圧-心拍数間の相互相関関数の最大値ρmaxを指標とすることにより, 情動反応の定量化を行うことが期待できる. しかし, これまでの方法では連続血圧の計測に大型で高価な計測装置が必要であるところが欠点であった. そこで本研究では, 自作した小型で安価な装置で計測できる脈波伝播時間を用いてもρmaxが得られることを示すとともに, 9人の被験者に対する情動反応誘発画像提示実験により, このようにして得たρmaxが情動反応を有意に反映するものであることが示された. |

| Abstract | Mayer wave(10s period or 0.1Hz fluctuation)included in heart rate variability and blood pressure variability appears apparently in the resting state. On the other hand, it can be predicted that a strong emotional reaction may affect the relationship between these variabilities. This prediction suggests that the human emotional reaction can be quantified by the maximum correlation coefficient ρmax between heart rate and blood pressure whose frequency components are limited to the Mayer wave-band. However, the conventional method of obtaining ρmax needS a bulky and expensive deviCe for measuring continuous blood pressure. In this study, a smaller and cheaper device for measuring pulse wave transmission time(PTT)has been developed. This paper has shown that the PTT can give ρmax instead of blood pressure and that ρmax obtained by the PTT may significantly reflect the emotional reaction on the basis of an experiment using nine healthy subjects with nine self-produced devices in which pictures were presented to the subjects to induce their emotional reactions. |
