Unlike the human brain, which heals poorly after injury or disease, flatworms possess the remarkable ability to regrow their brains entirely. A team at the University of Georgia has now identified several genes that enable this regenerative process.
The study highlights how flatworms harness their own cellular machinery to rebuild brain tissue, a feat that remains impossible for humans. By pinpointing these genes, the researchers aim to better understand the mechanisms behind regeneration.
While the discovery does not yet offer a treatment for human brain damage, it provides a clearer genetic blueprint for how some animals achieve full neural regrowth. The findings could eventually guide efforts to stimulate similar repair processes in people.
