Figure 2: (a) The mean current amplitudes of pH currents at pH 5, 6, 6.5, and 6.8 are not significantly different between groups injected with pH 4.0 (Injection 1, ; Injection 2, ) and controls injected with pH 7.2 (Injection 1, ; Injection 2, ), or uninjected controls ( ). (b) Data from (2A) was normalized to the peak transient currents evoked by pH 5 to analyze pH dose responses. pH dose responses and were not different between groups injection with pH 4.0 (Injection 1, ; Injection 2, ) and those injected with pH 7.2 (Injection 1, ; Injection 2, ) or uninjected controls ( ).
