a, Neurogram recording from a chronically endo-N-treated embryo showing a spontaneous bursting episode. Top trace, femorotibialis. Bottom trace, sartorius. Calibration bar, 1 sec. b,Motoneuron counts from the lumbar lateral motor column at st. 36 after treatment with endo-N, dTC, or both together.dTC (*) is significantly different from control (see Fig. 2 legend). dTC plus endo-N (**) is significantly different from dTC treatment alone by two-tailedt test, p = 8.62 × 10⁻³ (one tail) and p = 0.0172 (two tail) but also significantly different from control by two-tailedt test, p = 0.0291 (one tail) andp = 0.0583 (two tail). Endo-N treatment alone (⁺⁺) is not significantly different from control by two-tailed test, p = 0.0309 (one tail) andp = 0.0618 (two tail), but it is significantly different from the combined dTC plus endo-N by two-tailed t test, p = 0.0182 (one tail) and p = 0.0364 (two tail).
