| Outline of Final Research Achievements |
To investigate the truth of the replacement of Homo Neanderthalensis (HN) by Homo Sapiens (HS), we adopt neurocognitive and computational neuroanatomical approaches. We developed an integrative analytical framework for elucidating the anatomical and functional differences of the brain between them. The results of morphometry showed that hemispheres of cerebellum were larger in HS than those in HN. Our neuroimaging studies also demonstrated that the cerebellum play an important role for variety of highly cognitive functions such as attention, language, working memory, social cognition, creativity. Moreover, we revealed positive correlation between cerebellar volume and some cognitive abilities in modern humans. The present study indicates that HS utilizes their brain more efficiently with employing the cerebellar functions, which maybe one of the possible causes for the replacement.
