Membrane properties of MEC stellate cells from HCN1+/+ and HCN1−/− mice
HCN1+/+ | HCN1−/− | p | |
---|---|---|---|
Resting membrane potential (mV) | −68.5 ± 0.6 | −75.0 ± 0.5 | 5.2e-13 |
Input resistance (−ve) (MΩ) | 43.9 ± 3.2 | 73.2 ± 4.7 | 2.8e-6 |
Input resistance (+ve) (MΩ) | 55.2 ± 3.9 | 87.3 ± 7.1 | 1.8e-4 |
Time constant (−ve) (ms) | 9.3 ± 0.9 | 20.4 ± 1.3 | 6.1e-10 |
Time constant (+ve) (ms) | 10.3 ± 0.8 | 19.8 ± 1.6 | 1.1e-6 |
Sag | 0.62 ± 0.01 | 0.80 ± 0.01 | 1.2e-17 |

Input resistance and membrane time constant were calculated from membrane potential responses to negative current steps (−ve) and positive current steps (+ve). The membrane potential sag ratio (Sag) was calculated from responses to negative current steps. For HCN1+/+ mice, n = 45 for resting potential and input resistance and n = 41 otherwise. For HCN1−/− mice, n = 53 for resting potential and input resistance and n = 43 for other properties.
