Networks of interacting neurons are responsible for the cognitive
information processing in the brain. They must remain functional also in
the presence of noise and need to be stable as stochastic systems. In
this case the introduction of a noise term to the evolution equation
should not change the dynamics qualitatively. This postulate should be
valid for the vast majorities of biological networks [...]
Ah, mira, açò vindría a donar-me la raó sobre el que dic sovint sobre el
tema del sorroll en aquesta llista. És clar, que una cosa es una xarxa
d'interaccións neuronals i una altre és el que pugui ser aquesta
llista... però bé, sempre es bò trobar-ne coses comuns. Tu creus calamar
que aquest postulat sería aplicable aquí, idò?
Stochastic Escape and Stochastic Resonance: A particle trapped in a
local minimum may escape this minimum by a noise-induced diffusion process;
a phenomenon called “stochastic escape”. Stochastic escape in a driven
bistable system leads to an even more subtle consequence of noise-induced
dynamics, the “stochastic resonance”. [...] Stochastic escape occurs in
many real-world systems. Noise allows the system to escape from a local
minimum where it would otherwise remain stuck for eternity.
As an example, we mention stochastic escape from a local fitness maximum
(in evolution fitness is to be maximized) by random mutations that play
the role of noise.

Què és un "bistable system"? i un "local minimum"? M'encanten els
paralelistmes que puguin haver entre la biología i el wetware que
poguesim estar ejecutant aquí, però no sé a què et refereixes, calamarix
:) Explica't una mica, va, que em sembla molt interessant...
pd: molt bona la indirecta del "caos" ;)
