[Reactive invagination of the neuroepithelium in anlages of the human neocortex, tectum of the midbrain, and the retina at various stages of development].
Intensity of invagination of neuroepithelium of neocortex of human embryonal anlages of neocortex, tectum of the midbrain and retina was studied as a response to mechanic damage of ventricular zone induced in the course of preparation of the anlages to explanation. It was shown that no invagination formed in 24 hrs of the explantation. In neocortical anlage intensity of invagination was meximal in 6.5 wks embryo. In tectum invagination intensity of th explants lowered gradually from wk 5 to wk 7.
