The researchers say they got nerve cells to send signals to each other.
Scientists at the University of Utah in the US have revived the eyes of a deceased organ donor. This was reported by the Daily Mail.
Noted that in this way, the researchers discovered that the light-sensitive retina cells of a deceased person’s eye could respond to light within five hours after death. In addition, they can exchange signals with each other, just like in life.
These nerve cells in the retina are part of the central nervous system (CNS). These include the human brain and spinal cord.
To revive the eyes of a deceased organ donor, scientists restored the supply of oxygen and other nutrients to the eyes 20 minutes after removal from the donor.
“We were able to activate light-sensitive cells in the macula lutea of the human eye, which are responsible for visual acuity. These cells, even 5 hours after a person’s death, still respond to bright and even in dark light.. Now we wonder if brain death is really the end? ” noted by scientists.
The discovery could help develop new treatments for vision loss, they said.
It will be recalled that last year in Israel, CorNeat specialists and surgeons from Yitzhak Rabin Medical Center restored the vision of a 78-year-old patient previously diagnosed with total blindness.
