Here, we will explore two different IFFL designs that use either … WebNov 19, 2024 · Incoherent feed-forward signaling of a positive feedback loop with distinct regulatory thresholds of the two arms of the feed-forward loop are the key requirements for such emergent behaviors. Our calculations show that the specific types of atypical bistable responses depend on the logic gate configuration of the signals.

We demonstrate the capability of an Incoherent Feedforward Loop motif for the differentiation between sustained and oscillatory input … WebNegative feedback loops provide precise control of endocrine secretions (Fig. 13-3 ). The controlled component of the negative feedback loop can be ion concentrations, physical parameters (e.g., blood pressure), and hormone concentrations. Stimulators of endocrine gland secretion also have important trophic effects.
