Biophysical properties of uninjured and injured RS neurons following right spinal HTs at 10% BL and recovery at ~4–5°C
| N | Vrest, mV | Vth, mV | VAP, mV | VfAHP, mV | VADP, mV | VsAHP, mV | |
|---|---|---|---|---|---|---|---|
| Uninjured | 7 | −78.3 ± 4.9 | 14.9 ± 3.4 | 108.8 ± 5.0 | −3.39 ± 2.07 | 3.96 ± 1.20 | −2.09 ± 0.74 |
| Injured | 30 | −77.3 ± 6.7 | 15.6 ± 3.9 | 105.8 ± 8.2 | −3.71 ± 2.09 | 3.80 ± 1.80 | −1.87 ± 0.67 |
Values are means ± SD for uninjured RS neurons (left side of brain) and injured RS neurons (right side of brain). Following a right spinal HT at 10% BL and recovery at ~4–5°C for 2–17 wk (see methods), the properties of injured RS neurons were not significantly different from those for uninjured RS neurons (unpaired t-test). Also, the above parameters for injured RS neurons did not appear to differ substantially from those of uninjured lamprey RS neurons reported in a previous study (not shown; N = 31 neurons, McClellan et al. 2008).
