 Information processing in biochemical networks

 
From the previous talk it will appear that several networks in the immune system do work in under-percolated regimes. As a consequence attention should be paied on small cliques of interacting B and T clones alone.
In this talk I will show that the biochemistry underlying these dialogues has the same mathematical structure of dynamical systems in (biological) neural networks as well as that of transfer-functions in the electronic counterpart. 
In particular I will show how to relate cooperative/ultrasensitive kinetics (biochemistry) with ferromagnets (statistical mechanics) and operational amplifiers (electronics); anticooperative kinetics (biochemistry) with antiferromagnets (statistical mechanics) and flip-flops (electronics). 
Bio-Logic stochastic gates will be constructed via statistical mechanics, proved to work properly via logic and tested on real data regarding the related biochemistry.
