| Outline of Final Research Achievements |
Vision plays a vital role in sensing an object moving toward or away from self. The retinal motion input can result from either the actual motion of objects in the external world (i.e., ‘object motion’) or self-originated movements (e.g., eye movements). Here, we revealed for the first time that the visual area V3A shows a higher response to objective compared to retinal motion-in-depth, which suggests significant involvement of V3A in the processing of in-depth object motion.

| Academic Significance and Societal Importance of the Research Achievements |
眼球運動に依らない物体奥行運動推定の脳メカニズムの解明は，心理学・神経科学上の重要性のみならず，視線の動きを制約しない自由観視条件において，人がステレオ3D映像中の物体運動をリアルに感じている程度を，脳活動計測に基づき客観的・定量的に評価できる新たな映像評価技術の開発につながる等，工学的にも重要な意義がある．
