Proton‐evoked (pH 5.3) currents in mouse DRG neurons. (A) examples of transient plus sustained currents (top), sustained‐only currents (middle), and transient‐only currents (bottom). (B) numbers of neurons responding to low pH with patterns illustrated in A with pH ≤ 6.3. (C) Frequency histogram of peak amplitude of transient currents. The line represents the best‐fit to a Gaussian distribution with mean = 137 pA and standard deviation = 96 pA.
