abstract = "Temperatures outside the preferred range require flies to acutely adjust their behavior. A new study finds that heat-sensing neurons provide input to fly circadian clock neurons to extend the daytime siesta, allowing flies to sleep through excessive daytime heat.",

note = "Funding Information: The data from multiple groups support a working model (Figure 1) in which at high temperatures inputs from AC thermosensitive neurons to DN1p clock neurons delays siesta onset2 and decreases nighttime sleep4, and at cool temperatures inhibition of DN1a clock neurons by thermosensory projection neurons shifts the siesta earlier, suggesting a morning-specific role of DN1as in regulating timing of siesta onset1. However, the circuitry underlying the extension of siesta into the late day at high temperatures remained undefined. Alpert et al. find that increasing temperature from 25°C to 30°C for 24 h increased daytime sleep by widening the mid-day siesta, including extending the siesta into the late day. Blocking synaptic transmission of either ACs or LPNs prevented heat-induced increases in late day sleep. These data add to the nuanced literature on daytime sleep regulation by temperature and identifies LPNs as the key clock cell group regulating siesta extension at high temperature.
