The word "nostalgic" has a wide variety of textures. It is thought that the diversity of textures is created by the memory aspect of "that day, that place," and "those days," and the emotional aspect of "happiness" and “bittersweetness".

In this study, which was selected as a Grant-in-Aid for Young Scientists, we will elucidate the neural representations of textures such as "bittersweet memories of those days" through functional MRI studies focusing on (1) the hierarchy of autobiographical memories (episodic and semantic autobiographical memories) and (2) emotional valence (positive and negative), which constitute nostalgia.
