Human parietal retrieval states prioritize an absent temporal reference to reconstruct event order

Chengmei Huang, Jing Fu, Ruimin Wang, Isao Hasegawa, Koji Jimura, Kiyoshi Nakahara

The paper shows that human parietal retrieval states prioritize reconstructing event order by referencing an absent temporal milestone rather than directly recalling the target.

Beyond Temporary Scaffolding: Persistent Hippocampal Engagement and Brain-Wide Network Reorganization in Remote Memory Consolidation

Ruimin Wang, Ruedeerat Keerativittayayut, Shuya Morioka, Masaki Takeda, Isao Hasegawa, Koji Jimura, Kiyoshi Nakahara

This paper challenges the standard model of memory consolidation by showing persistent hippocampal engagement and brain-wide network reorganization during remote memory retrieval.

Hippocampal-midcingulate connectivity is associated with representational integration during cognitive map updating

Jing Fu, Chengmei Huang, Ruimin Wang, Isao Hasegawa, Koji Jimura, Kiyoshi Nakahara

This study investigates how hippocampal-midcingulate connectivity supports the integration of updated spatial associations during cognitive map updating.

Neural oscillatory activities in separate frequencies encode hierarchically distinct visual features

Hiroto Date, Keisuke Kawasaki, Isao Hasegawa, Takayuki Okatani

The paper shows that theta and gamma brain oscillations encode distinct levels of visual features using deep learning models trained on primate data.
