The development of safer vehicles and protective devices such as helmets is based on estimating the risk of injury in an impact. Right now, in the development of these safety systems, the measure of risk to the head is based on deceleration signal produced in a crash test dummy during a test.

In the future injury risk will be measured using methods that better reflect the mechanisms of injury in an impact. Increasingly, these mechanisms are being investigated using computer simulations of head impact. However, quite how these simulations should be calibrated is unknown – it has been difficult to determine what magnitude of physical stress is required to injure the brain.

This project will seek to investigate this. By examining the response of the sheep’s brain to a controlled indentation, we can examine how the function of the brain is altered by physical stresses, and what level of stress is required to trigger an injury response. The results will allow criteria to be developed for use with computer simulations of head injury, which in turn will allow better measurement of head injury risk in any given situation.

Our hypothesis is that a quantitative relationship exists between mechanical forces induced in traumatic brain injury (TBI) and the resultant brain pathophysiology. Accordingly, the objective of this project is to characterize the relationship between mechanical strain and brain injury in a sheep model of human TBI. This will be achieved through a detailed study of the pathophysiological response of the brain to direct load. Imaging and histology will be used to quantify the injury response, and a computer model of the experiment will be used to quantify the mechanical strain.

This project is a collaboration between Dr Robert Anderson at the Centre for Automotive Safety Research at the University of Adelaide, Professor Robert Vink, Professor of Neurosurgical Research, the Head of School of Medical Sciences, and the Deputy Executive Dean of Health Sciences at the University of Adelaide, and will also involve Associate Professor Tetsuya Nishimoto of Nihon University, Japan.

We are honoured and grateful for the support of the Brain Foundation in the pursuit of our research.
