Figure 1From: Perineural resiniferatoxin selectively inhibits inflammatory hyperalgesiaLocating the sciatic nerve for electrically-stimulated percutaneous, perineural RTX injection. Note finger palpation locations and direction of the needle (see Methods). Fluorescein dye injection (50 μl, 1 μg/μl) using this technique demonstrates the distribution of dye-containing fluid within the perineurium of the nerve (B).Back to article page
