Biomedical Engineering expert Dr John Mulvihill and his research group are one step closer to solving Traumatic Brain Injury (TBI).
The team are evaluating the mechanics that result in injury, also termed “mechanopathology”. The Dural Venous Sinuses are large veins within the skull that play an important role in blood draining from the brain. It is becoming evident that they are significant for dampening forces from potentially concussive impacts due to their unique collagenous structure, and how they attach to the skull and brain. This study is the first to test the stiffness and strength of these veins and demonstrate their potentially important role in the mechanopathology of concussion.
Dr Mulvihill’s next step is to quantify the mechanical and structural damage of concussive impacts to the tissues in the brain to better understand the effect of these impacts to the cells within our brain; “By understanding how and when damage occurs in our brain, we can better predict a threshold for injury. This can lead to improved safety designs in helmets, vehicles, and long-term assessment of brain injuries”.
Globally an estimated 40 million people are affected annually by Traumatic Brain
