    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.

    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.

    cAMP_in_dend
    Represents diffusion, from a volume of 9e-20 to 5e-18. Assuming neck dimensions of 0.1 x 0.1 microns, this works out to a diffusion const of about 270 um^2/sec, which is pretty conservative. It is what cAMP does in frog cilia.
    ** This is a trasport reation between compartments of different volumes. Therefore Kd is not applicable. Please Note Kf, Kb units are in number of molecules instead of concentration
