Summary

  1. 1.

    We have failed in the early stages of development to separate neuroblasts from glioblasts with the means of electronmicroscopy. All cells forming the wall of the neural groove or tube have the same cytological structure seen in other primitive somatic cells.

  2. 2.

    Some identification is possible around the 7th day of incubation when synaptic differentiation permits the recognition of neuroblasts.

  3. 3.

    Neurons are characterised by a continuous and prolonged formation of granular ER which eventually becomes organized in parallel cisterns around the 14th–16th days when typical Nissl bodies can be recognized.
