Plain Bilayer Membrane
A plain lipid bilayer is approximately an ideal capacitor. The equation for an ideal capacitor is
Failed to parse (Missing <code>texvc</code> executable. Please see math/README to configure.):
Here C is a constant (parameter), the capacitance of the membrane, proportional to area.
Next V(t) is the membrane potential.
Next I(t) is the current into the membrane, with a sign such that a positive current depolarizes the cell. The sign conventions are TRICKY!!! I get confused all the time.
