We hypothesized that the SCN entrains rhythms in the paraventricular nucleus (PVN) to time the daily release of corticosterone.

Loss of Bmal1 in CRH neurons causes arrhythmic PVN CRH calcium activity and reduces the amplitude and precision of daily corticosterone release.
Daily corticosterone release depends on coordinated clock gene rhythms and neuronal activity rhythms in both SCN VIP neurons and PVN CRH neurons.
Activation of SCN VIP neurons reduces corticosterone release and PVN CRH calcium activity, whereas inactivation increases them.
