| Research Abstract |
The present study was carried out to visualize the spatiotemporal patterns of neuronal network activities in suprachiasmatic nucleus, the center for mammalian circadian clock. To this goal, I have developed fast scanning single or multi-photon confocal microscopy and methods to load calcium sensitive dye in large neuronal population in suprachiasmatic nucleus. I successfully recorded synaptically-induced or spontaneous calcium concentration changes from hundreds of neurons in deep brain tissue at high spatial (single cell level) and temporal resolutions (millisecond scale).
