脳震盪とは何でしょうか。みなさんが想像するものとは違うかもしれません。元アメフト選手であり生物工学者のデイビッド・カマリロは、脳震盪が起こるメカニズムと、そして運動用ヘルメットが有効な保護にならない理由について、最先端の研究を紹介します。未来の脳震盪対策の姿をご覧ください

なぜヘルメットでは脳震盪を防げないのか―何で防げばよいのか

Most helmets protect against skull fractures, but do little to stop concussions, which happen deep within the brain—not at its surface. New research reveals that when the head rotates rapidly, forces travel down the brain’s center and stretch vital connections, often causing lasting harm. Even childhood bike riding is a leading cause of sports-related concussions. Promising new technology, like airbag collars, could slow head movement and reduce injury, but regulations must catch up before these innovations reach everyone.
