Marklose Nervenfasern im III. und IV. Ventrikel des Kaninchen- und Katzengehirns

A Scanning and Transmission Electron Microscopic Observation of the Fourth Ventricular Floor in the Mouse

“…The ultrastructure of the ependyma and its cilia, using a transmission electron microscope, has been studied by TENNYSON and PAPPAS (1962), BRIGHTMAN and PALAY (1963), KOHNO and USUI (1966), TAKEICHI (1966), LEONHARDT and LINDNER (1967), HIRANO and ZIMMERMAN (1967), LEONHARDT (1968), LEONHARDT and PRIEN (1968), NAKAI (1971), MILLHOUSE (1972), SCHINKO et al (1972), NOACK et al (1972, ROHRSCHNEIDER et al (1972), COATES (1973b) andBRUNI et 415 al. (1974).…”

“…CLEMENTI and MARINI (1972), NOACK et al (1972) and HOSOYA and FUSE (1973 suggested the possibility of the existence of neurons in the lateral and third ventricles. BRIGHTMAN and PALAY (1963), TAKEICHI (1966), LEONHARDT and LINDNER (1967), ROHRSCHNEIDER et al (1972) andNOACK et al (1972) reported unmyelinated nerve fibers upon or among the ependymal cilia in the whole ventricular system by transmission electron microscopy; most of these fibers may possibly belong to the processes of the supraependymal cells. However, the possibility that these supraependymal cells are neuronal in nature still can not be excluded.…”

“…by LEONHARDT and LINDNER (1967), and named "ependymal bleb" by COATES (1973b) are observable. This is supposed to be a large process of the ependymal cytoplasm as was pointed out by them.…”

Organon thalamo-chorioidalis in the taenia thalami of the cat and other mammals

“…1,5,6 ) or concave ( fig. 24), facing the ventricular lumen, is lined by ependym a which, at the tip of the TCB, merges with the Leonhardt and Lindner, 1967], occur on the ventricular surface of the ependym a (V in figs.5, 6; fig. 13).…”

Histological observations on the ependyma of the ventriculus mesencephali in the guinea pig

“…Leonhardt and Lindner [1967] denoted them as ' Kugeln' and Coales [1973] as ependymal bulbs. These authors suppose that they are large particles of cyto plasm of ependymal cells.…”
