The enormous incidence of closed head injury has resulted in employing the field of biomechanics as a means of predicting the site of a lesion, discovering, and understanding the forces acting during cranial impact. This paper indicates that the possibilities associated with trauma-induced lesions include: the establishment of large pressure gradients associated with damage resulting from absolute motion of the brain and its displacement relative to the skull; flexion-extension of the upper cervical cord; skull deformation and/or rotational acceleration. Analytical representations, inanimate and cadaver models and, experimental paradigms are presented and their behavioral implications discussed.
闭合性颅脑损伤的高发病率促使人们运用生物力学领域的知识来预测损伤部位、发现并理解颅脑撞击时的作用力。本文指出，创伤性损伤可能涉及以下方面：因大脑的绝对运动及其相对于颅骨的位移而产生的与损伤相关的巨大压力梯度；上颈髓的屈伸；颅骨变形和/或旋转加速度。文中介绍了分析模型、无生命模型和尸体模型以及实验范式，并讨论了它们的行为意义。
