Head injury in man and experimental animals: neuropathology.

All of the principal types of brain damage that occur in man as a result of a non-missile head injury, viz. cerebral contusions, intracranial haematoma, raised intracranial pressure, diffuse axonal injury, diffuse hypoxic damage, and diffuse swelling have been produced in subhuman primates subjected to inertial, i.e. non-impact, controlled angular acceleration of the head through 60 degrees in the sagittal, oblique and lateral planes.
