Scatterplot of the number of GABAB(1)-IR neurons in the ipsilateral L4 or L5 DRG of naïve rats or rats that underwent sham surgery or L5 spinal nerve ligation. Spinal nerve ligation caused a significant decrease in the number of GABAB(1)-IR neurons in the L5 DRG of both sham-operated and ligated rats compared with values in naïve rats. The numbers of GABAB(1)-IR neurons were unchanged in the adjacent L4 DRG. Each symbol is the number of neurons estimated from 8 or 10 optical disectors taken through the DRG of a single rat. Numbers adjacent to the symbol show the mechanical threshold of the ipsilateral hindpaw. Horizontal lines indicate the mean value. Ordinate: number of GABAB(1)-IR neurons. Abscissa: Treatment condition. NS: not significant. *P < 0.05; one-way ANOVA.
