About the Speaker
Amita Sehgal (University of Pennsylvania)

The focus will be on the mechanisms that drive the timing and the need to sleep. The 24 hour rhythm of sleep is driven by a circadian clock, while the need to sleep comes from a homeostatic system, which ensures adequate sleep levels. The lecture will show how the use of Drosophila has led to the identification of molecular mechanisms and circuits that underlie the circadian timing of behavior. It will also address a function for sleep and describe efforts to elucidate the genetic basis of sleep homeostasis.
