| Hermaphrodite L1 hatches with 202 somatic and 20 pharyngeal neurons; 80 postembryonic neurons are later added to the somatic nervous system to make a total of 302 neurons (no new pharyngeal neurons are generated during the postembryonic stages). All male-specific neurons, except CEMs are born postembryonically. |

| Total = 62 neurons are ciliated in hermaphrodites. In males, an additional 50 male-specific neurons are ciliated (4 in head, 46 in tail) (WA editors; Barr and Garcia, 2006) |
