|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.
