[Injury from the deceleration and acceleration of human skulls (author's transl)].
Diametral injuries of the skull accidental force may be accepted as an effect of summation of osseous and cerebral oscillations which cause a gradient of pressure inside the skull. The cavitations of liquor between cerebrum and skull are of no influence neither in a positive nor a negative direction in transmission of the vibration. Situated in an area which is not effected by the oscillation the hypophysis is protected against trauma. The causes for the contre-coup is to be seen in the anatomical and morphological specificity of the skull following Newton's axioms. Several concepts of the contra-coup are discussed.
