模型调节电路中的时变信息传输

Time-dependent information transmission in a model regulatory circuit

Francesca Mancini, Chris H. Wiggins, Matteo Marsili, Aleksandra M. Walczak

摘要:

许多生物调节系统处理非稳态信号,并以生理延迟响应。一个简单的调节模型,尊重这些功能,显示了延迟输出传输信息的能力是如何受到限制的:在短时间内由动态输入的时间尺度,在长时间内由动态输出的时间尺度。我们发现,最大信息网络的拓扑结构对应于通常发生的生物电路链接到压力反应和电路功能的稳定状态可能会利用吸收状态,以最佳方式传输信息。

英文摘要:

Many biological regulatory systems process signals out of steady state and respond with a physiological delay. A simple model of regulation which respects these features shows how the ability of a delayed output to transmit information is limited: at short times by the timescale of the dynamic input, at long times by that of the dynamic output. We find that topologies of maximally informative networks correspond to commonly occurring biological circuits linked to stress response and that circuits functioning out of steady state may exploit absorbing states to transmit information optimally.
