Fig. 2.

Neuron positions predicted by the quadratic dedicated-wire model vs. actual neuron positions. (Upper) Positions are normalized by the worm body length (0 = head; 1 = tail). Perfect predictions fall on the diagonal. Circles of the same color represent cell bodies belonging to the same ganglion. Three classes of pioneer neurons are labeled. (Lower) Schematics depicting the progression of pioneer neurons during worm development. Arrows indicate direction of neurite growth.
