Neurologists made the human eye “see” after death

(ORDO NEWS) — Experts from the University of Utah were able to make eye cells work after death. They described the experiment in an article in the journal Nature.

To better understand how nerve cells die from lack of oxygen, the scientists measured the activity of mouse and human retinal cells several hours after they died.

It turned out that stimulation with light leads to the formation of the same specific electrical signals in the retina as during vision in living mammals.

“We were able to awaken photoreceptor cells in the human macula, the part of the retina responsible for central vision and the ability to see fine details and colors,” the authors of the work explained.

Previously it was thought that changes in the nervous tissue occur quickly and irreversibly, but new data are likely to expand the possibilities for corneal transplantation.
