| Research Abstract |
We used a 2-dimensional sagittal-plane gelatin brain model and a finite element simulation model to elucidate the mechanism underlying brain damage in shaken baby syndrome(SBS). In the gelatin brain model, strain stress was higher in the frontoparietal and occipitoparietal regions than midbrain, and stress-related changes could be observed in the frontoparietal region near the brain surface. In the simulation model, the effects of stress and strain were clearly seen in the intraparenchymal region near the lateral ventricle. These results suggest that brain damage such as gliding contusion or subdural hematoma occur in SBS.
