The number of pSer845 GluR1-immunoreactive puncta in the medial half of each dorsal horn in a single optical section from three rats that received injections of 250 μg of capsaicin into the plantar surface of the hindpaw 10 min before perfusion fixation. The table shows the total number of puncta containing at least one pixel that exceeded the threshold luminance value (see Materials and Methods), the number of puncta per 1000 μm2, and the proportion of these puncta that were also GluR2 immunoreactive. The density of pSer845 GluR1-immunoreactive puncta was significantly higher on the ipsilateral side than on the contralateral side (p < 0.05; Mann-Whitney one-tailed U test).
