Electrophysiological properties of L3-5 dorsal root ganglion (DRG) neurons from Con, FM, and EA groups.

<p>(A) The action potential (AP) threshold was lower in the FM group than the control group. EA reduced neuronal excitation by increasing AP threshold, reversing the effect of acid injection. (B) FM induction decreased both AP rise and fall times compared to controls, effects also reversed by AE. (C) There were no significant group differences in AP amplitude and afterhyperpolarization (AHP) duration. (D) Data summary and statistical analyses.
