✦ Synopsis

The single oscillator feedback model describing the circadian system of the nocturnal insect, Hemideina thoracica, (Gander and Lewis, 1979) has been developed and refined by restricting the range of parameter values which successfully simulate the known behaviour of this insect's circadian system. The model accounts for Aschoffs Law for nocturnal animals, and makes new predictions on the combined effects of temperature and constant light on the period of the free-running rhythm, which were verified experimentally. These simulations also indicate that the same general feedback model can be used to describe the circadian systems of other organisms.

A control systems model for the photoperiodic clock is developed, which is an extended version of the earlier published "damped circadian oscillator model", and which consists of two feedback circadian oscillators, a "pacemaker" and a "'slave", both entrainable by light and by temperature. The pacem
