| Rm, MΩ | 81 ± 6 | 99 ± 6 | 89 ± 5 (P = 0.038)* |
| Vm, mV | –54.2 ± 1.0 | –60.3 ± 1.5 | –57.1 ± 1.0 (P = 0.002)* |
| Absolute firing threshold, mV | –48.2 ± 0.8 | –45.2 ± 1.2 | –46.8 ± 0.7 (P = 0.044)* |
| Threshold-Vm, mV | 6.0 ± 1.1 | 15.1 ± 1.9 | 10.3 ± 1.3 (P < 0.001)* |
| EPSPmax, mV | 8.0 ± 0.7 | 7.7 ± 0.9 | 7.9 ± 0.5 (P = 0.8) |
| Number of cells with sound-evoked spikes | 19 of 24 | 11 of 21 | 30 of 45 (P = 0.057) |
Values are means ± SE. Rm, input resistance; Vm, resting membrane; EPSPmax, maximal EPSP size reached during sound stimulation.
* Asterisk indicates differences between cells with and without evidence for the presence of Ih were significant (two-tailed t-test or χ2 test).
