The division of the lateral ventricle into the segments in white rat

The lateral brain ventricle (ventriculus lateralis) of the rat on the frontal serial histological slices was studied. Based on the change in the ventricle form in slices it was divided into the segments, marked by capital L (lateralis) and by the order number as segments L1 to L7. The method aims to serve as an aid for the simple denotation and easy identification of the examined part of the lateral ventricle during the morphological examinations.
