title: [Investigations on the basal dendritic tree of lamina-V-pyramidal cells in the visual cortex of rats after destruction of the lateral geniculate body and after dark raising (author's transl)].
abstract: The basal dendritic trees of the lamina-V-pyramidal cells of rats were investigated after 1th unilateral destruction of the dorsal lateral geniculate body (Cgld) 2nd dark raising I. Animals with destroyed Cgld. Comparing the data of free dendritic terminations (FDE), branching points (VZP), number of segments (AdD) and length of segments (LdD) no significant differences have been remarked between--controls of the same litter (non-influenced side),--influenced sides of animals of the same litter. A significant difference between the ipsi- and contralateral hemispheres of animals with unilateral geniculate destruction. II. Dark raised animals There were no significant differences between dark raised animals, their controls and between dark raised animals and controls. The causes of postoperative changings have been discussed. Mainly retrograde degeneration effects may be responsible for the ascertained differences.
