Description	In Drosophila, light and temperature cues can act as synchronization signals (Zeitgeber) of endogenous time with the daily cycles of light and temperature, but it is not known how they are integrated. We have shown that different sets of clock neurons play a role for synchronization to low and high temperature cycles with identical amplitude. This shows that temperature entrainment does not solely rely on measurement of temperature differences but rather on measurement of absolute temperatures. We show that this task is divided between different neuronal groups, opening the possibility that multiple temperature receptors - expressed either in different clock neurons, other neurons in the brain, or in the PNS - contribute to temperature entrainment. The blue-light photoreceptor Cryptochrome seems to actively block the entrainment strength of temperature both at a molecular and behavioral level, which most likely contributes to Zeitgeber integration.
