Comparison of epidural pressure in live anesthetized and post-mortem primates.

The response of the head to impact in the posterior-to-anterior direction was investigated with live anesthetized and post-mortem primates. The study was conducted at the University of Michigan Transportation Research Institute (UMTRI) under the sponsorship of the Motor Vehicle Manufacturers Association. 3-D motion and epidural pressures were experimentally measured. Interpretation of the results by simulating the tests using a 3-D mathematical model of the primate brain was done by Dr. C. Ward. The results of the tests and the simulation are presented to demonstrate the differences found between live and post-mortem primate brains.
