Abstract :
The physical modeling study presented demonstrates that cortical brain tissue deformation increases substantially when the applied loading is changed from the lateral to sagittal direction. This observation indicates that the direction of loading is an important parameter to consider when investigating the mechanisms of cortical heat injuries. Results from animal studies show that it is not only the magnitude and temporal loading characteristics but also the direction of loading that contributes to the type of injury produced. The two physical models in this study were used to determine the change in cortical brain deformation that occurs when the head undergoes inertial loading in different directions
