Different membrane properties of CA1 interneurons, CA1 pyramidal neurons, and dentate granule cells
| Cell type | n | Vm | Rm | Maximum firing rate | Sag ratio1-a |
|---|---|---|---|---|---|
| mV | MΩ | Hz | % | ||
| CA1 Interneuron (a) | 7 | −62.1 ± 0.8 | 540 ± 52 | 89.3 ± 13.3 | 7 ± 2 |
| CA1 Pyramidal (b) | 10 | −67.9 ± 0.9 | 230 ± 22 | 30.4 ± 3.4 | 39 ± 4 |
| Dentate granule (c) | 6 | −82.0 ± 1.3 | 51 ± 87 | 32.7 ± 2.8 | 3 ± 2 |
Data are presented as the mean ± S.E.M.
↵1-a The sag ratio was determined by measuring the voltage response to a hyperpolarizing current and then calculating the percent difference in the response at the end of the current injection compared with the maximum response.
