When the brain receives a traumatic injury, irreversible damage occurs as the cells at the point of impact die. Injured cells surrounding the area then release toxic substances, which cause the brain to swell. This decreases blood flow within the brain, leading to lower oxygen levels, which in turn leads to more cell deaths. Recently, however, scientists from North Carolina’s Wake Forest Baptist Medical Center have developed a new technique, that has greatly reduced the secondary cell deaths in brain-injured lab rats.
