Rostro-caudal distribution of pERK-LI cells in the Vc and C1-C2 following thermal stimulation of the facial skin. A: low-intensity (35°C), B: medium-intensity (40°C), C: high-intensity (50°C), D: mean number of pERK-LI cells in Vc induced by thermal stimulation (35°C, 40°C and 50°C) of the lateral facial skin in day 7 CNX and Sham rats, E: mean number of pERK-LI cells in C1-C2 induced by 35°C, 40°C or 50°C stimulation of the lateral facial skin in CNX or Sham rats. **: P < 0.01, #: p < 0.05, ##: p < 0.01 (vs. Sham).
