When an action potential propagates down a neuron, the charge across the membrane (membrane potential) increases. This causes the opening of voltage gated Na+ ion channels. When voltage gated Na+ion channels open, Na+ ions are allowed to rush into the cell. This causes the charge across the membrane to increase due to an increase in positive ions in the cell. A larger membrane potential causes more voltage-gated Na+ ion channels to open. This increases the rate at which Na+ ions enter the cell. This further increases the membrane potential, causing even more Na+ ion channels to open, causing more Na+ ions to enter the cell. This is an example of
