Larger Image Figure 10. Fast gating relaxations in D2O. Representative current traces from an inside out patch measured in the standard H2O solution (A) or in D2O (B) at pH/pD 8.3. The extracellular solution was in H2O. The pulse protocol consisted of a prepulse to −140 mV, test pulses ranging from 140 to −160 mV, and a tail pulse to 100 mV. The right panels show a zoom of the pulses to 100 mV, superimposed with a monoexponential fit (red line). Image published in: Zifarelli G et al. (2008) © 2008 Zifarelli et al.
