**M current**, often referred to as **M-type current**, is a type of ion current characterized by its dependence on the voltage across the cell membrane and its activation and inactivation kinetics. This current is generally mediated by specific types of potassium channels known as *M channels* or *KCNQ channels*. -M current plays a crucial role in regulating the excitability of neurons and other excitable cells.
