Repolarization is the process that restores the membrane potential of a neuron to its resting state after depolarization, characterized by a return to a negative internal charge. This is crucial for the proper functioning of neurons, allowing them to reset and be ready for the next action potential. It involves the movement of potassium ions out of the cell, which helps in reestablishing the negative charge inside the neuron and is essential for the propagation of nerve impulses.
congrats on reading the definition of repolarization. now let's actually learn it.
