| Description: Electrodes attached to a voltmeter record the potential across the axonal membrane. At the resting axon ion concentrations shown here, the voltmeter would read about 60 mV. If the axon is stimulated at point A by a depolarizing pulse, the traveling membrane potential will shortly pass point B, where it can be recorded.
