| Definition: | Primary neurons are neurons develop shortly after gastrulation during early segmentation stages, between 10-12 hpf, before the neural tube is formed. Each neuron occurs in a stereotyped location along the neuraxis. Axons from these cells grow via a growth cone pioneering a stereotyped pathway. These axons form the pattern of the early nervous system. |
