Summary
Background: Daily behaviors in animals are determined by the
interplay between internal timing signals from circadian clocks
and environmental stimuli such as light. How these signals are
integrated to produce timely and adaptive behavior is unclear.
The fruit fly Drosophila exhibits clock-driven activity increases
that anticipate dawn and dusk and free-running rhythms under
