Immunohistochemial analysis for spinal GABA and its receptors, GABAA and GABAB, among the naïve, allodynic and non-allodynic animals 2 weeks following neuropathic surgery. Behavioral differences among the groups are illustrated in Fig. 5A. (A) Microphotographs illustrating distribution of GABA-, GABA_A and GABA_B-ir in the S1 spinal segment ipsilateral to nerve injury. Scale bar=100 µm. (B) Relative staining intensities of GABA, GABA_A and GABA_B, compared to the naïve group. Immunoreactivities in both the allodynic and non-allodynic groups are not different from those of the naïve group.
