Direct demonstration of transsynaptic degeneration in the human visual system: a comparison of retrograde and anterograde changes.

Transneuronal degeneration of retinal ganglion cells was directly demonstrated in a patient who had unilateral removal of the striate cortex forty years prior to necropsy. For comparison, another case is presented showing anterograde transneuronal atrophy forty years after enucleation of one eye.

Conclusive Evidence for Human Transneuronal Retrograde Degeneration in the Visual System

Damage to axonal fibers in both central and peripheral nervous system leads to degeneration. The degeneration can be anterograde (Wallerian) in which injury to the cell body or proximal regions of the axon leads to degeneration in the axon distal to the damage. Retrograde degeneration is death of the cell body following axonal injury and can be seen throughout the Central Nervous System (CNS) i...

Trans-synaptic Retrograde Degeneration in the Visual System of Primates.

Although the first observations of trans-synaptic degeneration in the nervous system were made in the nineteenth century, the phenomenon has been something of an infrequent curiosity. From an experimental point of view it is not a particularly attractive field for study due to the time required for the full effects to become evident and may entail many months or even years of waiting. Consequen...

Retrograde transsynaptic degeneration of the inner nuclear layer of the retina

Eleven eyes with lesions of the optic nerve and chiasm and 5 normal eyes were histologically studied and cells of the inner nuclear layer were counted in specific meridians. There was consistent decreased cellularity in the 9 eyes in tohich lesions of the optic nerve had been present for 2 years or longer. The probability that the decreased celhdarity occurred by chance ivas less than 0.02. Ret...
