FIGURE 2.

Representative acid-evoked current responses in circumvallate and fungiform taste cells. Membrane currents were recorded at a holding potential of −60 mV. Arrowheads indicate 0 current level. A, a representative membrane current in response to pH 4.0 stimulus in a circumvallate taste cell (left). A current-voltage relationship is shown in the right. pap., papillae. B, a representative membrane current in response to pH 4.0 stimulus in a fungiform taste cell. C, off currents in circumvallate taste cells (267.7 ± 83.7 pA, n = 6) were significantly larger than those in fungiform taste cells (14.6 ± 1.2 pA, n = 4, *, p < 0.05). Data are shown as mean ± S.E.
