Abstract :
An investigation is conducted of the bifurcations of periodic solutions observed in coupled BVP equations with sinusoidal forcing terms. This system is considered as a circuit model for human circadian rhythms. Various states such as synchronization and internal/external desynchronization behavior in human rest-activity are studied through the analysis of the circuit dynamics
