Intrinsic properties of CCKBCs in sham control and IHK mice
| Animal group | Sham (n=12) | IHK (Ipsilateral; n=13) | IHK (Contralateral; n=8) | Significant differences One-way ANOVA |
|---|---|---|---|---|
| RMP (mV) | −60.0 ± 1.0 | −64.2 ± 1.2* | −62.6 ± 1.1 | p < 0.05 |
| Rinput (MΩ) | 189.4 ± 15.0 | 189.6 ± 15.6 | 197.6 ± 28.9 | ns |
| τmembrane (ms) | 17.6 ± 1.6 | 21.1 ± 1.9 | 16.9 ± 1.4 | ns |
| Sag amplitude (mV) | 8.8 ± 1.0 | 8.2 ± 1.1 | 7.9 ± 1.1 | ns |
| AP threshold (mV) | −37.7 ± 1.4 | −41.1 ± 1.1 | −39.0 ± 1.1 | ns |
| AP amplitude (mV) | 61.7 ± 2.7 | 68.1 ± 2.2 | 59.3 ± 3.5 | ns |
| AP half-width (ms) | 0.71 ± 0.03 | 0.66 ± 0.03 | 0.69 ± 0.03 | ns |
| AP frequency (Hz) | 43.8 ± 3.1 | 38.8 ± 2.9 | 45.0 ± 3.8 | ns |
See the methods section for descriptions of each of the measured intrinsic properties. The n values represent number of CCKBCs. AP frequency was measured from APs evoked by 1 s depolarizing current steps (300 pA). Abbreviations: RMP, resting membrane potential; Rinput, input resistance; τmembrane, membrane time constant; ns, not significant.
