| Research Abstract |
In this study, we investigated the role of NMDAR-mediated neuronal activity in the refinement of neuronal connections in the mouse barrel cortex. By developing novel sparse neuron labeling system, we found that NMDAR plays an important role for the dendrite refinement of barrel neurons during neonatal stages when barrel formation is in progress. We also developed a method for in vivo 2-photon imaging of neonatal mice brain, and observed the dendritic morphology of developing barrel cells.
