Abstract
The interaction of neuron and glia is essential for functional neuronal circuits. We have been especially focused on microglia, a sole immune cell in CNS. In addition to the pathological function of microglia, recent developments in molecular probes and optical imaging in vivo have revealed that microglia are highly motile cell in the healthy brain, extending and retracting their process that extend from a largely stationary cell soma. We reveal their physiological and pathological function on synapse and vessels. In this session, we will show microglial role for cross modal plasticity and show how they can contribute on sensory discrimination by their effect on neural circuit function. In addition, we will introduce our recent developed holographic microscope that can precisely measure and manipulate neuron and glial cell activities in a spatiotemporal manner in living mice to ultimately affect on behavior output. Furthermore, we will show our successful evaluation method to analyze the functional neuronal connectivity to integrate the transcriptome information.
