Ion channels following a Hodgkin-Huxley like formalism. The equilibrium open fraction and time constants are shown for each gate. They may be manipulated by dragging the curves, or with the corresponding sliders. Any number of gates may occur on a channel, and each gate can be raised to small integer powers to indicate identical serial copies.
