Positive feedback mechanism. A process whereby an initial change in an atmospheric process will tend to either reinforce the process (positive feedback) or weaken the process (negative feedback). See Feedback mechanism.
The basis for knowledge of the mechanism of the action potential is. The voltage clamp technique. Electronic feedback is used to set Em at whatever level the experimenter desires. The voltage clamp amplifier then keeps the Em at the level and measures the net ionic current that flows across the membrane.
