Plate 1

Represents the left half of the brain of a human embryo of 15.0 mm, C-R length with an estimated ovulation age of 37 days. It is a graphic reconstruction of the configurations of the nuclei forming the medial wall of the mesencephalon and diencephalon and the medial external wall of the anterior portion of the left cerebral hemisphere. This graphic reconstruction was done to provide a basis to which the series of embryos could be related, and was constructed ty serial cross sections. The term nucleus as used in these descriptions does not necessarily indicate a region directly comparable to a nucleus in the adult sense, but indicates an area of cellular concentration which can be identified in the forebrain of successively older embryos. The names given to the tracts and nuclei have been based on the names of corresponding nuclei and tracts in the adult brain wherever it has been possible to identilNr the embryonic structure with its adult derivitive.
