the expression of retinal degeneration was found to involve not only the disappearance of retinal receptors but also a reduction in thickness of the inner plexiform layer and a reduction of cell density in the ganglion cell layer : these changes were found to be associated with a reduction of neuronal density in the lateral geniculate nucleus , but not in the superior colliculus .
