Spike frequency was recorded in the nerve of the isolated superfused first gill arch of the bullfrog larva, Rana catesbeiana and the response to different superfusate PO2 was evaluated. In the metamorphic tadpole, spike frequency increased significantly when the superfusate PO2 was decreased (mean +/- SEM): 8.5 +/- 1.6 Hz at 650 Torr, 11.7 +/- 1.9 Hz at 140 Torr, 13.3 +/- 1.8 Hz at 65 Torr, 14.8 +/- 2.4 Hz at 0 Torr (ANOVA, p = 0.0002). The O2 sensitive chemoreceptor stimulants NaCN and almitrine also increased the spike frequency. This study demonstrates the presence of O2 sensitive chemoreceptors in the first gill arch of the tadpole.
