Plate 2
Plate II is a graphic reconstruction of the nuclear configurations forming the medial wall of the mesencephalon and diencephalon of the right half of a 12.5 mm., C-R length, human Embryo's brain, with the left cerebral hemisphere and the arterial and venous systems of the left side superimposed. Reconstruction of this type was used in order to illustrate, in two dimensions, the three dimensional aspect of the erabxyo brain. Serial cross sections were used to reconstruct structures lying lateral to the medial wall, with special reference to the blood vessels. Some of these sections are photographically reproduced in Figures A1 to A10 and are labelled on plate II, on the left, as planes A-L. The numbering of these planes, on the right, refers to the original sections.
Plates III and IV are enlarged reproductions of the areas outlined on the onion paper on plate II.
NUCLEI:
Plate II: Both diencephalon and telencephalon show the same nuclear structure as depicted in plate I but in a less expanded state.
