= Plateau potentials
{wiki=Plateau_potentials}
Plateau potentials are a type of sustained depolarization that occurs in certain types of neurons and muscle cells. They are characterized by a prolonged period of depolarization, which makes the cell membrane more positive and can lead to an extended period of action potential firing or muscle contraction. In neurons, plateau potentials are often associated with specific types of excitability and are involved in functions such as rhythm generation in certain circuits (e.g., in neurons of the cardiac pacemaker or certain motor neurons).
