and outputs.•The central complex promotes sleep and mediates sleep-drive.• …

Sleep is a complex and plastic behavior regulated by multiple brain regions and influenced
by numerous internal and external stimuli. Thus, to fully uncover the function (s) of sleep …

The circadian clock regulates animal physiological activities. How temperature reorganizes
circadian-dependent physiological activities remains elusive. Here, using in-vivo two-photon …

To survive adverse environments, many animals enter a dormant state such as hibernation,
dauer, or diapause. Various Drosophila species undergo adult reproductive diapause in …

Sleep is an essential and evolutionarily conserved behavior that is modulated by many
environmental factors. Ambient temperature shifting usually occurs during climatic or …

Small poikilotherms such as the fruit fly Drosophila depend on absolute temperature
measurements to identify external conditions that are above (hot) or below (cold) their …

Animals react to environmental changes over timescales ranging from seconds to days and
weeks. An important question is how sensory stimuli are parsed into neural signals …

Sleep is a biological enigma that has raised numerous questions about the inner workings
of the brain. The fundamental question of why our nervous systems have evolved to require …

Light discrimination according to colour can confer survival advantages by guiding animals
towards food and shelter and away from potentially harmful situations,. Such colour …
