電気関連7学会が連携して67名の碩学に対するオーラルヒストリーを実施してその記録を残すことができた。また、このオーラルヒストリーを通じて、インタビュイーの選定から成果のまとめに到る一連のプロセスについて方法論を学び、ノウハウを蓄積することができ、更に、各学会においてオーラルヒストリーに対する理解が深まり、自主的継続の機運が生じたことも本計画研究のもうひとつの成果であった。

We investigated the olfactory “Kansei” information processing for two kinds of smells by measuring the brain activities associated with olfactory responses in humans. In this study, the brain activities related to discrimination and recognition of odors were examined using functional magnetic resonance imaging (fMRI). In experiment 1, odor stimuli (lemon-like and banana-like) were presented using a block design in a blinded manner, and the kind of fruits was identified by its odor. The frontal and temporal lobe, inferior parietal lobule, cingulate gyrus, amygdaloid body and parahippocampal gyrus were primarily activated by each odor based on conjunction analysis. In experiment 2, as a result of performing an oddball experiment using the odors of experiment 1, the active areas were mainly found in the temporal lobe, superior and inferior parietal lobule, insula, thalamus, supramarginal gyrus, uncus and parahippocampal gyrus. Moreover, these regions overlapped with the emotional circuit. These experimental results suggest that common brain activities accompany the discrimination and cognition associated with odor stimuli, which may underlie the olfactory responses relevant to the higher brain function and emotions associated with olfactory function.
