For the nervous system to function, neurons must be able to send and receive signals. These signals are possible because each neuron has a charged cellular membrane (a voltage difference between the inside and the outside), and the charge of this membrane can change in response to neurotransmitter molecules released from other neurons and environmental stimuli. To understand how neurons communicate, one must first understand the basis of the baseline or “resting” membrane charge.

The lipid bilayer that forms the wall of a neuron (or glial cell) is not permeable to charged ions. However, there are a number of types of ion channels that allow ions to move down their concentration gradient across the membrane, and ion transporters that allow ions to move against their concentration gradient (from low concentration to high concentration). One of the best examples of an ion transporter is the sodium-potassium pump (also called Na+/K+ pump or Na+/K+ ATPase), which pumps potassium into a cell and sodium out of a cell, both against their concentration gradients, with the use of ATP to provide energy for the process. The actions of this pump sequester K+ inside of neurons and extrude Na+ from neurons (in other words, the sodium potassium pump causes intracellular K+ to be high and intracellular Na+ to be low, relative to the extracellular fluid).
