Functional characterization of rat and mouse TG neurons. A, fraction of cells responding to α, β-meATP (independently from their response to capsaicin), to capsaicin (independently from their response to α, β-meATP) or to both agonists for rat (left panel; n = 33) and mouse (right panel; n = 50). B, persistence of the responsiveness of rat TG neurons in culture to α, β-meATP and capsaicin. a, Proportion of cells responding to α, β-meATP (black bars; n = 7, 7, 10 cell cultures for the 1^st, 2^nd and 3^rd day, respectively) and capsaicin (grey bars; n = 7, 8 and 8 cell cultures for the 1^st, 2^nd and 3^rd day). b, peak amplitude of currents elicited by α, β-meATP (black bars; n = 22, 11 and 31 cells for the 1^st, 2^nd and 3^rd day, respectively) and capsaicin (grey bars; n = 16, 13 and 10 cells for the 1^st, 2^nd and 3^rd day). Only cells responding to the agonist were included in the current analysis.
