[Interaction of fibers from the retina and visual region of the cortex in several subcortical visual formations of rats].
The medial nucleus of the optic tract, the ventral lateral geniculate nucleus and the superior colliculus have been studied using the light (Nissl, Golgi, Viktorov) and electron microscopic methods in normal rats and in rats which survived for different periods after enucleation or occipital cortical lesions. Data were obtained on differences in terminal patterns of the afferent pathways. The study of the neuronal and synaptic organization of subcortical visual centers showed the distinctions and correlation between the complexity of neuronal and synaptic organization. Three types of interrelations between the optic and cortical pathways on the efferent neurons of the investigated structures are suggested.
