To understand development of complex yet sophisticated neuronal circuits underlying higher brain function of mammals, integrative studies which cover from molecules to whole animals are indispensable. By using a wide range of techniques, such as mouse genetics, molecular biology, in utero electroporation, histology and two-photon in vivo imaging, we are studying mechanisms of development and function of mammalian neuronal circuits. In particular, we are interested in activity-dependent circuit development during postnatal stages.
