How Does the Membrane Potential Work

The action potential is an explosion of electrical activity that is created by a depolarizing current. This means that some event (a stimulus) causes the resting potential to move toward 0 mV. … Action potentials are caused when different ions cross the neuron membrane. A stimulus first causes sodium channels to open.

How does the membrane potential change?

The membrane potential can change over time, allowing signals to be transmitted. These changes in membrane potential are caused by particular ion channels opening and closing, and thereby changing the conductance of the membrane to the ions.
