Effect of local inflammation of L5 DRG (LID) on excitability of sympathetic ganglionic neurons measured on POD 3–4. A Representative action potentials (AP) from neurons in isolated whole SG preparations from normal and LID rats on POD 3–4. B–D Average values of AP duration (B), rheobase (C), and input resistance (R _m) (D). **P < 0.01 compared with the normal group (Mann–Whitney test), n = 71 cells in the normal group (same cells as Fig. 2) and 25 in the LID group (from four male rats). Difference in rheobase approached significance (P = 0.09, Mann–Whitney test). Additional electrophysiological values are in Table 1.
