[Reorganization of the lateral geniculate body after deafferentation (experimento-morphologic research)].
One year after surgical section of the optical tract, the degenerative changes were found in the deafferented lateral geniculate bodies (LGB). The changes were species-dependent. In cats, the cytoarchitectonics was preserved, local neuronal losses and layers thinning absent. In night-active apes, with cytoarchitectonic image preserved and focal neuron necrosis absent, the layers were more substantially thinned. In apes with a primate-like LGB structure pattern, the extended zones of neurons degeneration were found in the layers. The most prominent deafferentation-induced structural LGB alterations were shown in the central vision projection zones.
