Portion I (0–10 min)	4.51±0.15	3.51±0.31	21.18±0.22	31.8±1.19	34.91±0.29	5.02±0.17
Portion II (10–20 min)	7.02±0.27	6.57±0.30	26.78±0.84	35.72±1.27	40.37±0.97	5.34±0.16
Portion III (20–30 min)	11.99±0.29	8.00±0.27	26.6±0.25	50.65±2.04	26.6±0.25	5.36±0.14

Notes: Baseline is the spontaneous neuronal activity before injection. Neuronal activity is divided by time. Firing rate is defined as spikes per second. Values represent mean ± SED.

Abbreviations: CCI, chronic constriction injury; GABA, gamma-aminobutyric acid; SED, standard error of the mean.
