Single-channel conductance

Data are means ± S.E.M. The frequency of the three conductance classes was calculated as a weighted mean ± S.E.M., based on the number of openings in each patch.

  • Significant differences in conductance (determined by ANOVA) to ACh (* P < 0.05; ** P < 0.01) are indicated. Otherwise, significant differences determined by pairwise comparisons to ACh ( P < 0.05) or to 4BP-TQS ( P < 0.05) are indicated.
