Peristimulus time histograms displaying examples of the effects of cumulative doses of the MEK inhibitor, PD98059, on ATP-evoked responses of TMJ units from (A) HE2-treated and (B) LE2-treated naive rats. The small calibration bars above the histograms indicate the time of intra-TMJ injection of 1 mM ATP.
