| Outline of Final Research Achievements |
To elucidate neural substrates for visual working memory, which is a neural function for maintaining visual information temporarily after its disappearance, I tried to develop a new mathematical method to model neural representations and to quantify neural representations of categories (e.g. “woman”, “talk”, and “cute”) during visual working memory. The developed method not only visualized neural category representations successfully but also was applied to a neural decoding technique to recover perceptual contents from brain activity in the form of words. Using this method, I found the cortical localization of category representations during working memory and the commonality of category representations between when visual information is directly perceived and when visual information is stored in working memory.
