    Notes: Abstract By means of a level crossing experiment the hyperfine structure constants of thez 6 P 7/2-level of Eu have been determined. The results areA=-6.51(6) MHz andB= 131.2(1.0) MHz in the isotope151Eu andA=-2.84(3) MHz andB=327.5(1.5) MHz in the isotope153Eu. Experimental data on the hyperfine splitting are available now for 11 of the 12 levels of the configuration 4f 7 (8S)6s 6p of EuI. These data are compared with the theoretical interpretation given by Bordarieret al. [1] which was based on only 7A-factors andB-factors. It is shown that the agreement between theory and experiment can be improved by taking into account configuration interactions.

    Comparative studies on the pre-and postterminal blood vessels in the cerebellar cortex of rhesus monkey, cat, and rat (1979)

    Notes: Summary In the rhesus monkey, cat and rat, pial arteries give off branches which run vertically through all three layers of the cerebellar cortex. The large cortical arteries are surrounded by a perivascular space in the molecular layer. Their wall consists of several layers of smooth-muscle cells and the luminal endothelium. As the arteries reach the deeper layers of the cerebellar cortex, the number of smooth-muscle cells is reduced. In the rat, sometimes no smooth-muscle cells are detectable in the preterminal arterial vessels. If these deep arteries branch off by dichotomy of terminal vessels there occurs a gradual or complete loss of myocytes in all three species. In the cat, where cortical arteries give off branches at rightangles, there is a sphincter-like accumulation of smooth-muscle cells at the opening to the smaller branch. The postterminal vessels and veins in all species exhibit the smae mural structure found in capillaries. The wall consists only of an endothelium and occasional pericytes embedded in the basal lamina. Even the large veins which run to the pial veins show this simple mural structure.

    Notes: Summary In the spinal cord of the rhesus monkey and of the cat paired vessels near the central canal are described. These paired vessels, consisting of one artery and one vein, are enveloped by a common glial sheath. In some Virchow-Robin's spaces two arteries and two veins can be observed. The physiological significance of this morphological feature is briefly discussed.

    Notes: Abstract We first show how to formalize environments in which situations can be changed only by action, and in which a situation should be brought about that is acceptable. This leads us to the concept of a problem constellation that consists of an action system, a reaction system, a judgement system, and an initial situation. We then present a cybernetical system which we call Robbimat. It is capable of testing problem constellations, of modifying them according to the results of the tests, and of judging the final constellation. We designed Robbimat in order to have favourable problem constellations automatically generated. As an example we discuss a simple game. It constitutes a win-loss-environment the structure of which can be deduced from the payoff function. We show how Robbimat analyses such an environment, and utilizing its structure classifies the initial situation.

    Cell number and cell density in the cerebellar cortex of man and some other mammals (1975)

    Notes: Summary The number of cells per unit volume was determined in the cerebellar cortex of man and 19 other mammals. The cell density (i.e. the number of cells per unit volume) decreases from mammals with a low brain weight to those with a higher brain weight. This decrease in the number of cells is found to be proportional for all three layers of the cerebellar cortex. In addition, the ratio of Purkinje cells to granule cells was determined. In contrast to the decrease of all cell types with increasing brain weight, this ratio varies remarkably among the mammals and is not correlated with brain weight. In man, this ratio is 1∶2991, while it is lower in all other mammals investigated. These differences in the ratio of Purkinje cells to granule cells and the decrease in cell density with increasing brain weight are discussed in relation to brain evolution.

    The myelinated parallel fibers of the cerebellar cortex and their regional distribution (1976)

    Notes: Summary In the cerebellar cortex of the Rhesus monkey and the cat, the supraganglionic plexus in the molecular layer exhibits regional differences. The plexus is very well developed in the vermal parts of the anterior lobe, but only poorly developed in the nodulofloccular lobe. Most of the fibers of this plexus are myelinated parallel fibers, which synapse in the typical manner with dendritic thorns of Purkinje cells. Only very few fibers of this plexus are recurrent collaterals of Purkinje cells. Their distribution throughout the cerebellar cortex does not display regional differences. These findings agree with physiological data on the disinhibition of Purkinje cells in different parts of the cerebellar cortex.

    The myelination of the cerebellar cortex in the cat (1978)
    Springer
    Cell & tissue research 188 (1978), S. 509-520 
    Details
    ISSN: 1432-0878
    Keywords: Cerebellar cortex (Cat) ; Postnatal development ; Myelination of efferent and afferent fiber systems ; Electron microscopy

    Topics: Biology , Medicine
    Notes: Summary The myelination of the cerebellar cortex of the cat was investigated in 61 cats aged from 3 hrs post partum to two and a half years. The first myelinated fibers appear at the time of birth in the central medullary ray. Before the onset of myelination, all fibers reach a critical diameter of about 1 μm. About the 14th day of life the number of oligodendrocytes in the prospective white matter increases markedly. Thereafter, the oligodendrocytes invade the inner granular layer. It therefore seems that the myelination of the cerebellar cortex proceeds from the central medullary ray towards the granular layer. At the 60th day of postnatal life, most of the afferent and efferent fiber systems are myelinated. These findings are discussed in relation to the development of function and the maturation of the electrical activity of the cerebellar circuit.
