|---|---|---|---|
| 24 h Control | |||
| Type I (10) | 19 ± 5 | 360 ± 200 | −56.8 ± 11.1 |
| Type II (12) | 16 ± 3 | 570 ± 310 | −53.0 ± 10.5 |
| 48 h Control | |||
| Type I (8) | 20 ± 6 | 270 ± 160 | −64.8 ± 8.6 |
| Type II (8) | 16 ± 3 | 580 ± 350 | −51.6 ± 5.9 |
| Acute I | |||
| Type I (7) | 19 ± 8 | 310 ± 210 | −50.0 ± 13.6 |
| Type II (10) | 20 ± 6 | 410 ± 360 | −48.8 ± 11.3 |
Values are means ± SD. n values are given in parentheses. One-way ANOVA determined that variations among means of capacitance, input resistances, and resting membrane potential values for type I or II neurons were not statistically significant. Cap, Cell capacitance; IR, input resistance; RMP, resting membrane potential.
