Comparison of the quantitative properties of the simulated APs to those generated by the pharyngeal muscles
| Parameter | Nematode | Model | Experimental data | |
|---|---|---|---|---|
| 1 | Maximal rate of upstroke [mV ms−1] | 15 ± 1 | 14.6 | (28) |
| 2 | Peak amplitude [mV] | 34 ± 3 | 34.6 | (3, 16, 29, 30) |
| 3 | Notch exists? | v | v | |
| 4 | Average potential of plateau [mV] | ~20 to 30 | 25 | (3, 26, 28, 29) |
| 5 | Average decrease rate of plateau [mV ms−1] | −0.22 ± 0.06 | −0.1 | (16) |
| 6 | Action potential total duration [ms] | 100 to 250 | ~175 | [16, 28 (WPD), 29, 30] |
| 7 | Action potential overshoot [mV] | ~−80 (−67 ± 1.5) | −80 | [28 (WPD), 29] |
| 8 | Average interpump potential [mV] | −73 ± 1 (−45 ± 1) | −73 | [3, 28 (WPD), 29, 30, 31] |
All values were inferred from intracellular recordings from TB muscles. Experimental data for parameters 7 and 8 suggest two possible values, where the nonchosen, alternative value is written in brackets. WPD—WebPlotDigitizer (27).
