Abstract :
Some additions/corrections are offered to Geddes, 2004. Stimulation is initiated by the second spatial derivative of the voltage along the nerve (activating function) rather than current density. Chronaxie values change with distance from the electrode. Anodic stimulation can excite via anodic break excitation, or via virtual cathodes around the anode.
