Our new paper with Masanao Igarashi and
about the nonequilibrium thermodynamics of large, disordered networks (the asymmetric SK model) was just published in Nature Communications 😀 https://nature.com/articles/s41467-023-39107-y… Thread about the main ideas of the paper

Brain circuits are generally asymmetrically connected, displaying reentrant connectivity and generating self-exciting activity. Perhaps one of the first to study it was Cajal’s student and cybernetic pioneer Lorente de Nó

Lorente de Nó participated in the first Cybernetics meetings hosted by Norbert Wiener, who in the first chapter of his seminar book realizes that such asymmetric structures must be governed by the physics of nonequilibrium, irreversible processes

A classic example of an irreversible process is a cup breaking. A movie of a cup breaking feels perfectly natural, but watching the same movie backward is strongly unintuitive. This is because of the emergence of an arrow of time of the entropy dissipated by the cup shattering

Neural and other networks can display a similar process. Networks in equilibrium (A) have attractors that organize the activity of the network, but behaviour is reversible. Networks out of equilibrium (B) can display interesting irreversible phenomena, like oscillations and chaos

Thermodynamically, out-of-equilibrium dynamics must dissipate entropy to the environment to sustain such irreversible activity. Thus, entropy production is a measure of the emergence of such dynamical dissipative structures
