Abstract

Newly developed finite-element brain models of a small primate, a baboon, and a human, are used to simulate animal and cadaver head impact tests. Kesponse measures of these three-dimensional models are compared to measured brain displacements and recorded pressures. The correlation between measured and computed response is the same in both the live animal and human cadaver tests. Brain displacements are found to be small, and pressure response is quickly damped.
