Examples of two-component recovery from inactivation following 1P and 10P test stimuli for WT cells. Each panel shows recovery from inactivation following a single 10-ms step to 0 mV (blue), and then following a 10-Hz train of 10 pulses to 0 mV (red). A total of 22 WT cells from 8 different animals were compared with the 1P and 10P protocols.
