Outline of Final Research Achievements

We move our eyes three times a second, but the world around us remains stable. How does the brain stabilize the visual world? We proposed and tested a "background coordinate hypothesis" that the displaced retinal images are integrated relative to the "background". In this study, 1) we demonstrated that "background coordinate neurons" do exist in the precuneus of monkeys, and 2) the stability of the visual world was impaired by disturbing the precuneus. The results of this research have provided a solid answer to the basic question of visual stability, which has been debated for more than 1000 years.

Academic Significance and Societal Importance of the Research Achievements

目を動かしても世界が動かないのはなぜか、という問題はすぐに体験できるだけでなく、1000年にわたって繰り返し議論されてきた「基本的な」問題である。「サッケード抑制」が標準的な回答とされてきたが、これは問の1/3程度を説明するに過ぎない。我々は先行研究を総合して、「脳のネットワークの中心である楔前部に背景を中心とする座標系が在ること」が回答であるという仮説を提案して、検証に成功した。この研究成果は、1000年来の問題に実質的な回答を与えたという意義があると考えている。
