Brain injury from the macro to the micro level and back again : what have we learned to date ?

This presentation relates the macroscopic with the more microscopic aspects of the biomechanics of central nervous system injury. A natural evolution in the field of injury biomechanics has taken place in recent years. Investigators have moved from the study of the macro to the micro world of biomechanics in order to obtain answers to the current questions of cellular and tissue failure criteria, as these relate to the macro issues of human injury tolerance criteria. This report briefly discusses this topic.
