Can sulci protect the brain from traumatic injury?
However, strain local to the sulci was reduced and increased in other areas. The authors also discussed that a 3D FE model can test the insights from that study with in vivo tolerance limits. Thus, there is inconclusiveness regarding the influence of the sulci based on these previous studies. A 3D study with detailed FE models having anatomical correct sulci might shed some light into this matter. The current study uses two detailed 3D FE models with and without sulci which are constructed based on an MR T1-weighted image. The mechanical responses of these models are compared in several impact simulations. A large number of brain trauma cases involve diffuse axonal injuries (DAI) which can cause complica- tions to the patients and even years of living with disability after hospitalization (O’Connor et al., 2007). The occurrence of DAI can be predicted by strain in the cerebral tissue (Margulies et al., 1990) and the most commonly occurring cerebral regions for DAI are the corpus callosu
