The purpose of this research is to discuss the basic study of mechanism of brain injury analytically with respect to pressure changes using some simple head models for FEM analyses and impact experiments. Two types of simple cylindrical models to discuss about thickness of CSF region were presented. From results of FEM analyses, we could confirm that pressure changes did not depend on the thickness of CSF. On the other hand, from results of impact experiments, we could confirm that pressure changes caused by a cavitation phenomenon depend on the thickness of CSF. From these results, we found that a contrecoup injury depends on the cavitation phenomenon.
