Before revision: A thirteen-state master equation for Na+ channel gating that describes the coupling between three activation sensors, a two-stage fast inactivation process and a slow inactivated state , may be reduced to kinetic equations for a six state system .
After revision: A fifteen state kinetic model for Na+ channel gating that describes the coupling between three activation sensors, a two-stage fast inactivation process and a slow inactivated state , may be reduced to kinetic equations for a six state system .
