[Retrograde transneural degeneration in the visual system: neuromorphological study and problems (author's transl)]

The unilateral resection have been done entirely or in part of the primary visual cortex in 10 cats with various postoperational delays. In all cases, some large and medium axons in the primary optic tract show signs of degeneration, leading to their disappearance along with an important glial reaction. As there in similar signs of degeneration, but apparently less important in all normal cats used for control, it is worth-while to reconsider the notion of retrograde transneuronal degeneration after cortical lesion.
