Velocity Response Curves Support the Role of Continuous Entrainment in Circadian Clocks
Speed response patterns support ongoing adjustment in internal body clocks

Abstract
A velocity response curve (VRC) offers a unified framework for understanding how circadian clocks adjust to light cycles.
- Circadian clocks in organisms are influenced by the Earth's daily light/dark cycle.
- Two theories of light entrainment, discrete and continuous, have historically been used to explain these adjustments.
- The VRC describes how circadian clocks continuously adjust their speed in response to light, contrasting with the phase-shifting behavior emphasized by the discrete theory.
- The VRC effectively explains experimental data from both discrete and continuous light conditions.
- Features of the VRC are linked to specific entrainment behaviors, including seasonal phase adjustments.
- A model based on the VRC successfully predicts clock behavior in natural fluctuating light environments.
