The critical temperature for this model is only determined by the branching ratio γ γ and the site-to-site interaction energy ϵ ϵ , a fact which may have direct implications associated with neural structure vs. its function (in that it relates the energies of interaction and branching ratio to its transitional behavior.) For example, a relationship between the transition behavior of activities of neural networks between sleeping and wakeful states (which may correlate with a spin-spin type of phase transition) in terms of changes in neural interconnectivity ( γ γ ) and/or neighbor-to-neighbor interactions ( ϵ ϵ ), over time, is just one possible avenue suggested for further experimental investigation into such a phenomenon. In any case, for this Ising model it was established, that “the stability of the long-range correlation increases with increasing γ γ or increasing ϵ ϵ .”
