(a) The cell potential spatial regionalisation. (b) The protein regionalisation. (c) The time relaxations of V and p for the central cell marked by the arrow. As in Fig. 4, we consider the case of the positive regulation, but now for the decreased conductance ratio , which gives values of |V| higher than those of Fig. 4. Initially the cell potentials are depolarised (V = −8 mV) at the two small regions while the rest of the system is polarised (V = −59 mV). All over the system, we use the reference rate constants
. The electrical relaxation gives a predominantly polarised ensemble. The genetic relaxation results in high values of the protein concentration because of the positive regulation.
