Influences of the heterogeneities of the cerebral cortex for traumatic brain injury

Introduction Current numerical head models that are used to predict traumatic brain injury resulting from accidents have no detailed geometry of the cerebrum (Figure 1). Therefore, these head models have no direct link to tissue-based injury criteria. To investigate the influences of the heterogeneities of the cerebral cortex, a model has been developed with a detailed geometry of a small section of the cerebrum (Figure 1b, red box, and Figure 2).
