The genetic basis for individual differences in complex traits is still unclear. In order to clarify the mechanisms related to behavioral diversity, we are using a series of wild-derived mouse strains. Wild derived strains exhibit a prominent degree of wildness and phenotypic diversity among them. We are also developing efficient genome editing methodologies in rodents with CRISPR/Cas9. We are identifying genes related to behavioral diversity using these tools, and are aiming to understand the role of these genes in the molecular, cellular, and neural mechanisms that underlie this behavioral diversity.
