An Anatomically Representative Atlas-Based Finite Element Model of the Human Brain for Studying Brian Injury Biomechanics: Development, Validation and Comparison to Existing Models
Traumatic brain injury (TBI) is a leading cause of disability and injury-related death. To enhance our ability to prevent such injuries, we can study brain response using validated finite element (FE) models. In the current study, a high-resolution, anatomically accurate FE model was developed from …
