Scientists have revived light-sensing neuron cells in organ donor eyes and restored communication between them as part of a series of discoveries that stand to transform brain and vision research.

Researchers have identified distinct differences among the cells comprising a tissue in the retina that is vital to human visual perception. The scientists from the National Eye Institute (NEI) discovered five subpopulations of retinal pigment epithelium.

Molecular and cellular changes in rod photoreceptors are detectable in a mouse model of retinal degeneration several days prior to observable morphological changes, according to researchers at the National Eye Institute.
