It depends on how differentiated they are. There are some nerve cells that do replicate and there are nervous system malignancies and benign tumors that obviously replicate. Neurons have been known to grow, but after a certain level of differentiation, they will not replicate. Astrocytes, Gliomas, and other supportive nerve cells do replicate.

Careful this one. Are you saying, replicate or duplicate; linguistically even as regards the sciences, there is a difference...

In any case, neurology is finding fallacies all the time in what was formerly assumed regarding neurons and networks..
