title: [Morpho-histochemical investigations about the connection of the mesencephalic reticular formation (Area cuneiformis) to the subcortical structures of the visual system (author's transl)].
abstract: There was investigated the connection of the mesencephalic reticular formation (Area cuneiformis) with subcortical structures of the visual system. After coagulation of the reticular formation we studied the connections by degeneration and enzymhistochemistric methods. Terminal degeneration in different intensity was observed in the ventral part of the lateral geniculate in the nucleus lateralis posterior, the pretectal region and in the lower laminae (IV ... VII) of the superior colliculus. The findings are mainly ipsilateral. A direct projection to the dorsal part of the lateral geniculate could not be observed. By enzymhistochemic methods we localized the AchE intracellular in the rostral part of the area cuneiformis. After destruction of this area there was observed a clear diminishing of the AchE activity in the ventral lateral geniculate and in the area pretectalis. These results were confirmed by biochemical methods.
