| Outline of Final Research Achievements |
This study aimed at understanding biological mechanism of synaptic dynamics by cutting-edge imaging technologies. To achieve this goal, we analyzed morphology and function of excitatory and inhibitory synapses in the neocortex, maturation steps of individual synapses imaged in vivo by two-photon microscopy, and defects in synaptic functions and dynamics in mouse models of psychiatric disorders. From these experiments, we conclude that synaptic dynamics in the developing neural circuits show circuit-specific regulation mechanisms. Furthermore, we showed that early impairments in synaptic dynamics cause dysfunction of neural circuits in later stages of development.
