Abstract: | Summary This paper reviews the discovery and characterization of a behavioural system for entrainment of circadian rhythms. This behavioural system depends on non-photic inputs but interacts with the light-entrainment system. Non-photic stimuli can be powerful quantitatively: behavioural events can shift rhythms by several hours. Nonphotic entrainment offers scope for rephasing biological rhythms in circumstances where light input from the environment is inadequate. |
