title: [Volumetric relationships of the rat striatum and its traversing corticofugal and corticopetal pathways].
abstract: On histological slices, studies have been made on the striatal area and total area of the internal capsule bundles passing through the striatum. The predominant diameter of fiber bundles which pass via the striatum and form direct contacts with the callosal body is equal to 10-60 micrometers, their total number being equal approximately to 1,320. Average area occupied by the bundles at all levels of the striatum on frontal slices amounts of 30.7%. It means that about 1/3 of the striatal volume is formed by the internal capsule bundles, whereas 2/3 of its bulk are occupied by neurones.
