The head-withdrawal threshold to heat or cold stimulation of the tongue in the rats with 0.5 M Glu or vehicle injection into the whisker pad skin (A, B) and heat stimulation of the whisker pad skin in the rats with 0.5 M Glu or Veh injection into the tongue (C). Mean number of pERK-IR cells in Vc and C1-C2 following heat or cold stimulation of the tongue in the rats with 0.5 M Glu or vehicle injection into the whisker pad skin (D, E) and heat stimulation of the whisker pad skin in the rats with 0.5 M Glu or vehicle injection into the tongue (F).
