Outline of Final Research Achievements

Songbirds employ a sophisticated system of vocal communication via songs which consists from sound elements intricately combined. These features enables them to serve as effective animal models for analyzing the neural mechanism underpinning human speech production and perception. However, reproducing the natural process of vocal communication in controlled laboratory setting poses significant challenges. In this project, we have developed a system that isolates songbirds in a soundproof box, enabling the complex syllabic structures of their song to be decoded in a nearly real time manner, and provides artificial feedback signals through an LCD monitor. This innovative system has thus bridged a critical gap in the field, allowing for the replication of vocal sequence-based communication within an animal model in a laboratory setting. This represents a significant advancement in our capacity to study and understand the neural mechanisms of vocal communication.

Academic Significance and Societal Importance of the Research Achievements

鳴禽類はさえずりと呼ばれる音素を複雑に組み合わせた音声シーケンスを用いて他個体とコミュニケーションをとり、この際に多彩なシーケンスが使用されるため,同様に複雑なヒトの「ことば」の生成と認識の神経機構の生物学的基盤を解析する動物モデルとして使用される。一方で実験室環境で自然なコミュニケーションを取らせることは困難であった。本研究では、鳴禽類個体が発するさえずりをリアルタイムで解読するとともに液晶モニタ上のバーチャル個体を介して人工的に応答シグナルを提示する実験システムを開発した。これにより音声シーケンスによるコミュニケーションを動物モデルにおいて実験室内で再現することを可能にした。
