| Abstract: | Light and electron microscopic investigation has been made of the main structural components of the nervous tissue in two divisions of the telencephalon (the dorsal ventricular ridge and striatum) in 10-day chick embryos. Special attention was paid to the degree of maturation of cellular elements of the nervous tissue, the development of neuropil and the level of synaptogenesis. The data obtained suggest heterochronous maturation of the divisions investigated. Striatum, being phylogenetically more ancient structure, is formed prior to the dorsal ventricular ridge. |
