Symbol solver in single neuron and in network

A model is proposed that is based on an attempt to unify the informational duties of a biosystem and to describe a canonical way of solving any problem that can appear. A language is introduced to make a correspondence between neuron-molecular and behavioral levels that, on the one hand, could be realized at the molecular level and, on the other hand, could be formal basis for solving artificial intelligence problems. The physical solver operates with the physical symbols' predicates as symbol space elements. It solves equations expressed in predicates, but not numerical or functional equations. An experiment proving the existence of a physical solver is described.<>
