| Outline of Final Research Achievements |
Objects in our living environment are made of various materials (metal, wood, etc.). To understand the neural mechanisms underlying the material perception, we examined the neural activity in the inferior temporal cortex (IT) while the macaque monkeys were viewing the various materials. Most IT neurons showed selective responses to the material images. The material category representation of IT neurons was affected by the visuo-haptic experience of touching and seeing the real objects of various materials, and the influence of the visuo-haptic experience was maintained for about half a year.

| Academic Significance and Societal Importance of the Research Achievements |
我々は目の前の物体を眼で見るだけで、対象物体がどの素材によって作られているかを瞬時に判断することができ、さらに視覚的な情報（色や形）だけでなく触覚的情報（硬さや重さ）も感じ取ることができる。この素材知覚の多感覚性がどこで、どのように処理されているかの理解が一層進むものと期待される。
