Effects of selective glutamatergic receptors antagonists and intracellular signaling pathway inhibitors on quisqualate-induced increase in capsaicin-sensitive neurons. (A) Experimental design for the recording of capsaicin-induced calcium elevation. (B) The change in the proportion of capsaicin-sensitive (gray) and -insensitive (white) neurons in presence of selective glutamate receptor inhibitors with quisqualate. (C) The change in the proportion of capsaicin sensitive (gray) and insensitive (white) neurons in the presence of intracellular signaling pathway inhibitors with quisqualate. *p < 0.05, **p < 0.01 against control. ^##p < 0.01 against quisqualate-treated alone.
