Number of L5 ipsilateral DRG neurons 2 weeks after L5 and L6 spinal nerve injury.

	Small-sized	Medium-sized	Large-sized	Total
Sham C57BL/6J	371.6 ± 31.2	116.2 ± 10.7	18.6 ± 2.90	506.3 ± 42.3
SNL C57BL/6J	176.2 ± 18.4***	72.3 ± 6.64**	2.33 ± 0.59***	250.8 ± 21.9***
SNL Cav2.2-/- mutant	225.3 ± 25.2***	67.7 ± 8.62**	3.17 ± 0.72***	296.1 ± 30.2***

Each value represents the mean ± SEM (n = 12 in each group). **p < 0.01, ***p < 0.001, compared with Sham C57BL/6J (one-way ANOVA followed by Tukey's post hoc test). Numbers were obtained using conventional profile counting methods.
