Figure 5.

Action potential trajectories following manipulations of the expression and effective phosphorylation status of Kv3.4 in DRG neurons. A–E, Representative AP waveforms evoked by the indicated 0.5 ms current injection pulse. Insets, Corresponding phase plane plot for each group. F, Overlay of representative AP waveforms from the indicated color-coded groups. The RMPs for Kv3.4-GFP, WT, PN, PM, and DN were −56.8, −56.6, −59.2, –59.2, and −57.4 mV, respectively. For direct comparison of the AP trajectories, the RMPs of the overlaid traces are normalized.
