    This is a model of weak coupling between the AMPAR traffikcing bistability, and the CaMKII autophosphorylation bistability. In this model, there are three stable states: Both off, AMPAR on, or both on. The fourth possible state: CaMKII on but AMPAR off, is not truly stable, since over the course of hours the AMPAR also turns on.

    The stochiometry is a bit off here. Each NMDAR actually binds to a holoenzyme, about 12 CaMKII subunits. But our CaMKII calculations are in terms of individual subunits. So as a hack, we put in much more NMDAR than is actually there.

    Kd is calculated only for second order reactions, like nA+nB <->nC or nA<->nC+nD, where n is number and A,B,C,D are molecules, where as for first order reactions Keq is calculated. Kd for higher order reaction are not consider.
