Scientists have been able to demonstrate that light-sensitive neurons in the retina can respond to light within five hours of death.
In addition, they can prove that the eyes can communicate with each other after death. Scientists recorded signals from the eyes, which are similar to those from the eyes of living people. This and other advances raise the question of whether we can really reverse death.
They published their findings in nature. Among them, the researchers described their experiments in detail. Basically, they have found that cells respond to different types of light. In previous experiments, Yale researchers were able to restart the brains of 32 beheaded pigs. However, the new study goes further.
The idea of reversing death is not new. It has been described in the novel for many years, and scientists have been looking for ways to reverse aging for decades. But through this new study, scientists were able to recover B waves for the first time.
B wave is a slow and rhythmic oscillation. Scientists have found its existence in the brain of a living person and even in the brain of a dying person. The retina is part of our central nervous system. Therefore, it is a great breakthrough to let the cells in the retina talk to each other like living eyes. In addition, they hope this will help speed up eye experiments.
At present, many eye experiments are carried out on primates. However, if they can try to expand the process of reversing eye death, they can carry out these experiments on "live" donated eyes.
The researchers believe this could speed up new treatments to improve disease and vision loss. In addition, it can also improve our understanding of ocular neurodegenerative diseases.
Ultimately, reversing death may still be a long process. But through these new experiments, we are slowly finding a way to reverse the dial a little. And this may mean all the difference for disease research.
