| Outline of Final Research Achievements |
The suprachiasmatic nucleus (SCN), the primary circadian pacemaker in mammals, is a network structure composed of multiple types of neurons. However, the neural mechanisms underlying the generation of robust and stable circadian oscillation by the SCN network remains unknown. We generated mice with neuron type-specific genetic manipulations and performed analyses of their behavior, gene expression in vivo and ex vivo, and so on. We found that AVP producing neurons in the SCN play a critical role in the generation of stable circadian behavioral rhythms and the determination of the circadian period.
