研究実績の概要

In this research project, my primary objective was to compare the functional organization of the macaque and human cerebellar cortices. For macaque monkeys, data acquisition was successfully completed for high-resolution structural images by 2021 and for functional imaging by 2022. The comparison of the functional organization of the cerebellum revealed significant species differences, particularly in working memory, higher-visual, and default-mode networks. Interestingly, the human cerebro-cerebellar language network in macaque monkeys exhibit functional connectivity only auditory areas suggesting it is an early pre-language circuit. Unfortunately, the project experienced significant delays due to a failure of the 2023 Kobe RIKEN cloud server, where all the analyzed data was stored. This has caused substantial setbacks to the project. Nonetheless, manuscript is currently in preparation.
