Labelling of the supraoesophageal ganglion of postlarval Nereis virens with [3H]thymidine indicates that cell division is most active in very small worms, less than 0.1 g in weight. In such animals a few, small, labelled neurons were found, but only after 13 h of exposure to isotope. After shorter exposures, very small, undifferentiated labelled cells were seen in most of the ganglionic areas of the brain, although the various ganglionic nuclei differ in the time of first appearance of their characteristic neurons. In older animals gliagenesis continues at a reduced rate and neuron production becomes extremely slow.

Studies of a natural population of N. virens Sars at Southend reveal that the oocytes take a little over a year to mature. After a period of relative quiescence they grow rapidly between September and December and then increase little in size until early May. Within a given specimen small oocytes are more variable in size than large ones. Sperm develop fully from coelomic sperm plates in about eight months, and are mature by the beginning of May. There is a period during which they are characteristically clumped in quartets.
