- Relation between atrophy of the brain due to aging and relative motion between the skull and brain at head impact
抄録
<p>The purpose of this study is to clarify relation between atrophy of the brain due to aging and relative displacement between skull and brain by using the physical head-neck model during rotational impact. The physical head-neck model consists of skull part, brain part, neck part and head-neck joint part. The shape of skull and brain part was based on real-shaped three dimensional CAD data and polygon data constructed by CT/MRI images. We constructed two different shaped brain models. One model has the brain shape of young adults reproduced (hereinafter called adult physical head-neck model), and the other is model whose volume is reduced by 10% than it (hereinafter called aging physical head-neck model). The various conditions of rotational impact were given to these models and measured relative displacement between skull and brain occurring in each model. The relative displacement between skull and brain is calculated from the position data of each marker photographed by two high-speed cameras. As the result of that, it was found that the relative displacement between skull and brain is larger in the aging physical head-neck model than in the adult physical head-neck model. Therefore, it was revealed that brain atrophy due to aging increases the relative displacement between skull and brain when rotational impact is applied to the head.</p>
