| Slope (Hz/mM or 1/min mM or V/mM) | p value | R2 | Figure | |
|---|---|---|---|---|
| preBötC composite frequency (Hz) | 0.021 | 3.0E-14 | 0.55 | 2A |
| XII motor output frequency (Hz) | 0.024 | 2.0E-17 | 0.68 | 2A |
| Sigh frequency (1/min) | 0.074 | 1.9E-8 | 0.53 | 2D |
| Burst amplitude (V) | 0.049 | 0.673 | 0.002 | 3A |
| Burstlet amplitude (V) | 0.179 | 0.0001 | 0.19 | 3B |
| XII amplitude (V) | 0.148 | 0.497 | 0.01 | 3C |
[K+]o was changed from 3 to 9 mM in 1 mM steps. All results were analyzed using linear regression analysis. Number of slices (n) at each [K+]o (mM, n): (3, 12); (4, 9); (5, 8); (6, 12); (7, 8); (8, 8); (9, 19).
