| Research Abstract |
To know the intercellular system that keeps the synchrony among oscillator neurons in the SCN, we developed two projects to delineate the intrinsic synchronizing systems. We got two bland new findings. (1) Synchrony between dorsomedial SCN (DMSCN) and ventrolateral SCN (VLSCN) is possibly attained by VIP and VPAC2 system. (2) We found that the SCN is divided into two parts in relevance to period of circadian rhythm. Medial small part containing oscillators with a period less than 24 hours and the rest of the SCN with a period longer than 24 hours.
