A 4D Atlas for Studying Cell Development in Worms

For more than 50 years, scientists have used the roundworm Caenorhabditis elegans (C. elegans)—a hermaphroditic nematode that is widely recognized as an important tool for genetics, cell biology, and neuroscience research. The entire adult nervous system and cell lineage of C. elegans was mapped in 19861 and since then, scientists have used this map of neuron connectivity to help elucidate diverse neurobiological mechanisms. Compared to the 100 billion neurons in the human brain, C.
