Outline of Final Research Achievements

We examined the physiological features of parallel olfactory pathways in the cockroach. In the cockroach, general odors are processed by two separate populations of secondary olfactory neurons, type1 and type2 projection neurons (PNs). Intracellular recordings revealed olfactory properties and temporal patterns of both types of PNs. Type1 PNs were narrowly tuned but exhibited high sensitivity to effective odors. Type2 PNs were broadly tuned and exhibited clear dose-dependencies. Next, we revealed that odor-evoked responses were temporally complex in type1 PNs, while type2 PNs exhibited phasic on-responses with either early or late latencies. Simultaneous intracellular recordings and pharmacological experiments revealed that the early and late latencies of type2 PNs might be driven by activities of sensory neurons and local interneurons, respectively. These results suggest that two parallel pathways might employ different neural strategies to encode odor information.

Academic Significance and Societal Importance of the Research Achievements

本研究では原始的な昆虫であるワモンゴキブリにおいて、匂い物質を処理する脳内並行経路を発見し、それぞれの経路で匂いの濃度や質など異なる側面を抽出し処理していることが明らかになった。このような平行嗅覚路は哺乳類では一般的に報告されているが、昆虫ではミツバチで報告されているのみで、その匂い情報抽出の神経基盤はわかっていなかった。研究成果より、並行嗅覚経路を架橋する抑制性のGABA作動性ニューロンが二次嗅覚ニューロンの匂い応答潜時を厳密に制御していることが明らかになった。原始的なゴキブリをモデルとし、嗅覚並行処理の神経機構を明らかにすることで今後の嗅覚情報処理研究の一助となるであろう。
