Figure 5
Photomicrographs showing capsaicin-induced c-Fos-ir cells in the dorsal horn of L5 2 h after s.c. injection of capsaicin alone (a), (b), or combined with MK801 ((c), 1 mM) or with CNQX ((d), 1 mM). All data presented are mean ± SEM obtained from six animals. (a), (c), and (d) ipsilateral side. (b) contralateral side. Solid line indicates 100 μm.
