Subject: Variable Resistors with time

Help! I'm trying to develop a circuit model that models the flow of ions when light is absorbed in retinal rod cells. I need to find a way to incorporate a variable resistor into the circuit that when light is absorbed the resistor will increase and cause a capacitor within the circuit to discharge. Is it possible to model the resistance source so that at certain time intervals the resistance will increase and then decrease back to a certain resistance and then repeat the process again several seconds later? THe increase in the resistor should cause a decrease in potential across that resistor.
