Properties of Ih at 23°C and 33°C in bursting and regular-spiking subicular neurons
| gmax (nS) | Vh (mV) | Vc (mV) | τ (ms) | |
|---|---|---|---|---|
| 23°C | ||||
| Bursting (n = 22) | 5.3 ± 0.5 | −76 ± 2 | 8.8 ± 0.2 | 117 ± 6 |
| Regular spiking (n = 13) | 2.2 ± 0.6* | −73 ± 2 | 8.7 ± 0.6 | 133 ± 9 |
| 33°C | ||||
| Bursting (n = 18) | 6.1 ± 0.5 | −72 ± 1 | 10.7 ± 0.8 | 35 ± 3 |
| Regular spiking (n = 7) | 3.2 ± 0.9* | −75 ± 2 | 10.8 ± 1.1 | 42 ± 8 |
The parameters maximal conductance (gmax), voltage of half maximal activation (Vh) and slope factor (Vc) were determined from the fit of the Boltzmann equation to the voltage-dependent activation. τ is the time constant of activation at −120 mV.
