Figure 3. Charge conservation.

Figure 3

A, charge movement currents recorded in response to depolarizing pulses to −10 and +20 mV of increasing duration (2 ms increments) to evaluate charge movement conservation. B, QON or QOFFvs. pulse duration for the complete set of pulses of corresponding traces illustrated in A. The normalized charge-pulse duration relationships for both QON and QOFF are fitted to single exponential functions (continuous lines). The calculated QON time constants were 12.7 ms for pulses to −10 mV, and 2.3 ms for pulses to +20 mV.
