Outline of Final Research Achievements |
To clarify a selective and direct suppressive system in the brain, in which postnatal experiences change innate responses, we analyzed the stress-related activities of glomeruli in the olfactory bulb (OB) using predator odor induced stress responses. In the OB, a specific odorant receptor innervates spatially distinct glomeruli forming mirror-image maps. Our results suggest that simultaneous activation in both medial and lateral OB is necessary for inducing neural activities in the piriform cortex where might cause stress-like behavior.

Academic Significance and Societal Importance of the Research Achievements |
動物の持つ先天的な反応が経験によって改変される際の選択的な脳内抑制システムを解明することは、感性における個体差の形成過程を明らかにするための重要な知見をもたらすと思われる。これらの結果を総合的に解析することが、ヒト個々人において感性の相違を生じる重要な要因を解明するために有用であると考えられ、ヒトそれぞれ個別の刺激に対する意図的なリセットや反応抑制などが可能となり、各個人における生活の質(Quality of Life (QOL))の向上にも影響を与えるものと期待される。
