| Outline of Final Research Achievements |
To investigate neural representation of high-dimensional space of Shitsukan percption, we studied two problems. One problem is how the high-dimensional space is divided and labelled, and the other is how the different values along a specific dimension is discriminated. With regard to the former problem, we studied how various materials are distinguished in the brain mainly by using functional MRI (fMRI) technique in humans and macaque monkeys. With regard to the latter, we studied how gloss information is represented in the macaque brain by using fMRI and single unit recording technique. We found that, in both cases, information related to Shitsukan perception was represented in higher ventral areas. We also conducted experiments using multi-channel recording technique and in vivo visualization of neural connections, and found that multiple sub-regions existed in the higher ventral visual area of the marmoset and they formed a neural network.
