ABSTRACT
The present paper is intended as a continuation of preceding publications (Bergquist, 1959 a, b) on possible causes of the phenomenon of ‘overgrowth’ (Patten, 1952) in the brain of the chick embryo. Reference should be made to these publications for the relevant literature. In these earlier investigations, it was observed that the mitotic rate in the altered portions of the neural tube seemed higher than in the normal regions, and that the hemispheres and tectum opticum showed marked folding.
