Definition of Ion channel. Ion channel: A protein that acts as a pore in a cell membrane and permits the selective passage of ions (such as potassium ions, sodium ions, and calcium ions), by means of which electrical current passes in and out of the cell.
This article describes the role of ion channels in neurophysiology and the disturbances that lead to neurologic disorders. Ion channels also act as targets for drug action. Examples of drugs targeted to ion channels for the treatment of neurologic disorders are given. Examples of epilepsy and neurodegenerative disorders are given to provide a glimpse into the impact of knowledge of ion channels on the future management of neurologic disorders.
