The results presented above show that, during the normal postnatal ontogenesis, regional brain cells, oligodendrocytes, and neurons fuse and form heterokaryons. The oligodendrocytic nucleus in a heterokaryon changes according to the pattern of the neuronal nucleus to which it is fused.

To create a new hybrid, homokaryons are combined, or crossed, to form heterokaryons. Heterokaryons are cells that contain multiple genetically different nuclei (Figure 1).
Heterokaryons can not be identified because protoplasts of the parents were of the same type and shape.
