Atomic-scale model unravels ion channel gating

U. ILLINOIS (US)—Nerve cells power human intelligence and behavior through electrical signals that rely on potassium and sodium ion channels to do their job, and an important part of that biological process involves a gating mechanism for generating and controlling the signals in those channels. (more…)
