Abstract

A study was made of human embryos at the end of 8 weeks and foetuses aged 9 weeks. It was shown that at the beginning of the foetal period the cortical plate, which is the primordium of the neocortex, covers the whole surface of the cerebral hemisphere. The plate consists of 8–12 rows of densely packed cells. Below the cortical plate is the subplate.
