Book excerpt: To better understand brain injury mechanisms and better predict brain injuries under impact, this work focuses on the analysis of experimental brain motion data and the development of brain injury models. An analytical method is used to separate the measured brain motion into rigid body displacement and brain deformation with a minimum total squared error. Under mild impact, it is found that the whole brain has nearly pure rigid body displacement, having a magnitude of 4 to 5 mm in translation and +/-5 degrees in rotation. As the impact becomes more severe, the rigid body displacement is limited in magnitude for both translation and rotation, while the increased brain motion primarily is due to brain deformation, which is largest in the superior region of the brain.
