A Symmetric Dual Feedback System Provides a Robust and Entrainable Oscillator
Figure 1
Biochemical network maps of the circadian clock models with different types of loop coupling logics.
A: The single feedback model, B: the semi-dual feedback model, C: the dual feedback model, D: the redundant feedback model. The notation of CADLIVE [46]–[48] is used for simplifying the diagram. The dashed circle represents nucleus.
