Book is published from Iwanami Science Library.

I published a book that explains the "frontier research of memory" in an easy-to-understand manner for the general public. Due to a remarkable progress in the memory research in recent years, I think it will soon be possible to understand the true nature of memory. The motivation was to share these newest findings and I hope that there will be more various people in general start taking an interest in the field of neuroscience.

I included my research philosophy and a message for young people.
