[Stereological analysis of the vascular network of the ganglionic eminence and the corpus striatum during brain development in man].
A study of the volume density of the ganglionic eminence vascular network and the constituent parts of the corpus striatum was performed on 8 chosen foetal brains, which were well-injected with a mixture of India ink and gelatin, aged from 14-25 postovulatory weeks. The volume density of the ganglionic eminence vascular network amounts to 0.0209-0.0300 mm0, of the caudate nucleus to 0.0131-0.0181 mm0, of the putamen to 0.0136-0.0159 mm0, and of the globus pallidus to 0.0121-0.0159 mm0. The comparison of the results obtained, shows that the volume density of the ganglionic eminence vascular network is higher than the volume density of the other examined structures and that this difference is statistically highly significant (p less than 0.01). The augmented volume density of the ganglionic eminence vascular network points to a possibility of slow blood flow through its vascular bed, which was experimentally demonstrated on animals. This slow blood flow, among other factors, may be the cause of a ganglionic eminence venous infarction in premature newborns of low birthweight.
