From: Mechanisms involved in extraterritorial facial pain following cervical spinal nerve injury in rats
Rostro-caudal distribution of pERK-LI cells in the Vc and C1-C2 following mechanical stimulation of the facial skin. A: low-intensity (6 g), B: medium-intensity (15 g), C: high-intensity (60 g), D: mean number of pERK-LI cells in Vc induced by noxious mechanical stimulation (60 g) of the lateral facial skin in day 7 CNX and Sham rats, E: mean number of pERK-LI cells in C1-C2 induced by 6 g, 15 g or 60 g stimulation of the lateral facial skin in CNX or Sham rats. *: p < 0.05, **: P < 0.01 #: p < 0.05, ##: p < 0.01 (vs. Sham).
