A team of neuroscientists led by the University of Texas Medical Branch in Galveston has come closer to finding a treatment for traumatic brain injury.

Transplanting human neuron stem cells into rats that have suffered traumatic brain injuries reverses the damage and allows the brain’s nerve cells filaments to reconnect, researchers say in a new study.

Previously, numerous studies showed that transplanting stem cells in lab animals with brain trauma improved their brain function significantly. But scientists had been puzzled about how these improvements happened.
