    Notes: Summary The number of Golgi cells per unit volume was determined in different regions of the cerebellar cortex of man and of ten other mammals. Despite the general belief in the uniform architecture of the cerebellar cortex, regional differences in the distribution of Golgi cells were found. In the inferior parts of the vermis, the number of Golgi cells per unit volume is twice that in the corresponding hemispheres. In addition, there are differences between the anterior and inferior parts of the vermis. These differences are a feature of the cytoarchitecture of the cerebellum in man and all the investigated mammals. The ratio of Purkinje cells to Golgi cells was also determined and found to differ in different species. In man, this ratio is 1∶1.5, while in the monkey and cat it is almost 1∶1.9 and in the rat 1∶3.3. These differences in the ratio of Purkinje cells to Golgi cells are discussed from the point of view of cerebellar evolution.

    Description / Table of Contents: Zusammenfassung In der Kleinhirnrinde des Menschen, des Rhesusaffen und der Katze formen die rückläufigen Kollateralen der Purkinjezellen im unteren Drittel der Molekularschicht einen markhaltigen Plexus, den Plexus supraganglionaris. Dieser Plexus ist nicht in allen Abschnitten der Kleinhirnrinde gleichmäßig entfaltet, sondern zeigt starke regionale Unterschiede in seiner Dichte. Im Lobus nodulofloccularis, dem ältesten Kleinhirnabschnitt, ist der Plexus im Wurmanteil nur spärlich entwickelt, im dazugehörigen Hemisphärenanteil dagegen etwas stärker ausgebildet. Im Lobus posterior des Corpus cerebelli ist er im Wurm und in den Hemisphären nur sehr diskret angelegt. Seine stärkste Entfaltung erfährt der Plexus supraganglionaris im Lobus anterior des Corpus cerebelli. Hier nehmen im Wurmabschnitt die rückläufigen Kollateralen beinahe das untere Drittel der Molekularschicht ein, während der Plexus in den Hemisphärenanteilen nur schwach entwickelt ist. Die mögliche Bedeutung der regional unterschiedlichen Dichte des Plexus supraganglionaris für den intracorticalen Erregungsablauf wird diskutiert.
    Notes: Summary In the cerebellar cortex of man, rhesus monkey and cat the recurrent collaterals of the Purkinje cells form a myelinated plexus, the plexus supraganglionaris, in the lower third of the molecular layer. This plexus does not exhibit a uniform distribution in all parts of the cerebellar cortex but its density varies considerably in different regions. In the eldest part of the cerebellum, in the lobus nodulofloccularis, the plexus is developed sparsely in the region of the vermis, somewhat more, however, in the corresponding part of the hemispheres. In the lobus posterior of the corpus cerebelli there are only few collaterals in the vermis as well as in the hemispheres, while the plexus supraganglionaris is best developed in the lobus anterior. Here in the region of the vermis rather the lower third of the molecular layer is occupied by recurrent collaterals while in the hemispheres only a sparsely developed plexus can be observed. The possible importance of the regional differences in density of the plexus supraganglionaris in regard to the transmission of excitation is discussed.

    Notes: Summary In the cerebellar cortex of rhesus monkey and cat differences in the arrangement of basket cell axons and dendrites are described. In the anterior lobe, basket cell axons are short, very small in number and of a small diameter. In the posterior and nodulofloccular lobe, these fibers form plexus-like accumulations within the lower third of the molecular layer. In these parts they are longer, more numerous and bigger in diameter. Finally the contribution of Lugaro cell dendrites to this fiber accumulation is discussed.
