How much is known about the level of injury the brain can recover from? Over what time period does the brain adapt to an injury?A lot is known about brain plasticity immediately after an injury. Like any other injury to the body, after an initial negative reaction to the injury, the brain goes through a massive healing process, where the brain tries to repair itself after the injury. Research tells us exactly what kinds of repair processes occur hours, days and weeks after the injury.What is not well understood is how recovery continues to occur in the long term. So, there is a lot research showing that the brain is plastic, and undergoes recovery even months after the brain damage, but what promotes such recovery and what hinders such recovery is not well understood.It is well understood that some rehabilitative training promotes brain injury and most of the current research is focused on this topic.
