This behavior is not consistent with the notion that INaP arises solely from a bell-shaped window conductance that results from the overlapping steady-state activation and inactivation curves of the fast Na+ current in a narrow voltage range, nor with the notion that INaP is generated by a single uniform conductance independent of the fast Na+ current. 5.
