Research Field

Our lab started in July 2021 to understand fundamental mechanisms of postnatal brain development and to clarify the origin of developmental disorders such as autism. Infants’ brains undergo dynamic functional and structural changes during the first year of life. We aim to elucidate this process by studying the roles of synaptic proteins in the maturation of neural circuitry. We use multidisciplinary approaches that span molecular, synaptic, circuit, and behavioral levels. By applying these techniques to the mouse models of developmental disorders, we aim to find a solution that could provide a novel therapeutic strategy. Please refer to:
