Signaling with Poisson-like processes: Theory and applications

Abstract:
Information transfer in biological systems is often mediated by some background Poisson-like process (spiking activity of cortical and sensory neurons provides an example) which is modulated in time by the transmitted signals. How to reveal information encoded in such a signal-carrying noise? How to quantify its amount? Can information transmission be improved by ambient noise for arbitrary signals of finite duration (nonstationary stochastic resonance)? I will discuss these problems from an information theory perspective within a simple and tractable framework provided by nonstationary Poisson processes with the signal-modulated rate. A generalization to the case of two-state Markovian noise (e.g. flipping of an ion channel between open and closed states) will be also considered.
