These results provide supportive evidence that sNPF-producing neurons promote long-lasting increases in sleep, and show for the first time that even brief periods of activation of these neurons can cause changes in behavior that persist after cessation of activation.

Light and the neuropeptides PDF and sNPF act dynamically at distinct hubs of the circadian neural circuit to produce multiple suppressive events that create the proper tempo and sequence of circadian pacemaker neuronal activities.
