||Note-According to Sulston 1983, PMID 6684600 p. 92 right column, there are 222 neurons present in the newly hatched L1 hermaphrodite. P.2 top paragraph: "The structure and connectivity of the nervous system of the nematode Caenorhabditis elegans has been deduced from reconstructions of electron micrographs of serial
sections. The hermaphrodite nervous system has a total complement of 302 neurons, which are arranged in an essentially invariant structure. Neurons with similar morphologies and connectivities have been grouped together into classes there are 118 such classes. Neurons have simple morphologies with few, if any, branches."
