Megjegyzések:	Results of axonal labelings with CoCl2, cobaltous lysine and cobaltic lysine complexes are compared on dorsal roots and nerves of the spinal cord and brain stem in the living frog. The most satisfactory staining of fibres and terminals is given by CoCl2; its application however, is limited by its rather short (6--10 mm) axonal transport. Cobaltous lysine is transported somewhat better, but it gives a poor fibre staining in the spinal cord. The axonal transport of cobaltic lysine is the best, covering a distance of 40--50 mm. Combination of cobaltic lysine with 2--5% dimethyl sulphoxide greatly enhances the axonal uptake of cobalt and extends the distance of transport to 70--80 mm. It is assumed that better transport of cobalt complexes is achieved by their less toxic effect on the nerve cell.

Cím:	Different dendritic arborization patterns of motoneurons in various places of the rat's lumbosacral spinal cord / Székely G., Matesz C., Antal M.
Dátum:	1980
Megjegyzések:	With the aid of the cobalt labelling technique the distribution and morphology of motoneurons were studied in the 2nd and 3rd lumbar segments of the rat's spinal cord. On the basis of arborization patterns of their dendritic arbors, motoneurons can be classified into six groups. 1. Large stellate-form neurons occupy the centre of the ventral horn. 2. Marginal neurons are found at the ventrolateral border of the ventral horn. 3. Horizontal neurons form a small group in the dorsolateral corner of the ventral horn. 4. Upper stellate neurons situate in the dorsal part of the ventral horn. 5. Triangular neurons constitute a compact group in the medial corner of the ventral horn. 6. Unclassifiable neurons form a scattered group in the ventral part of the ventral horn. The arborization pattern of dendrites of adjacent neurons belonging to the same group frequently resemble one another to such an extent that they are called "twin" neurons and derive probably from a common cell lineage. One member of such twin pairs is often the small counterpart of its much bigger mate. Dendrites originating from the same morphological type of motoneurons and running in the same direction, aggregate into smaller or larger bundles. The majority of dendritic bundles is oriented in, or close to, the transversal plane of the spinal cord; a significant number of longitudinal dendrites are found only in the group of triangular neurons innervating the axial musculature. The possibility is discussed that the differentiation of the different forms is determined both by genetic and epigenetic factors during morphogenesis.
