A resetting signal keeps circadian rhythm on track in Drosophila fruit flies

g clock resets the evening clock every day, without changing the intrinsic speed of the evening clock. Between daily resets, therefore, the evening cells time evening activity with their own clock, but they will always start counting time from the moment they were reset by the morning cells. In other words, the evening clock triggers the alarm at its own pace, but it is the morning clock which sets the alarm every day.

"So if you are looking over several days, only one period will be observed ?the one dictated by the morning clock," Stoleru said.

Research by the same Brandeis team, published last year in Nature, had shown that two distinct groups of clock neurons determine morning and evening activity. The present study greatly advanced the understanding of how temporal coherence between these two cell groups, and between their behavioral outputs, is achieved.
