Regeneration helps repair learning and memory after injury in mice
Newborn nerve cells may help heal the brain after a traumatic injury.
In a study in mice, blocking the birth of new neurons hindered the mice’s ability to learn and remember a water maze after a brain injury, researchers from the University of Texas Southwestern Medical Center at Dallas report in the March 30 Journal of Neuroscience. The finding could help settle a debate about what new nerve cells do for the brain and may eventually change the way brain-injured patients are treated.
