Qu'est ce qu'une commotion cérébrale - Clifford Robbins
"Chaque année aux États-unis, on recense chez les joueurs de sports et d'activités de loisirs entre 2,5 et 4 millions de commotions cérébrales. A quel point les commotions cérébrales peuvent être dangereuses ? La réponse est complexe, et réside dans la façon dont le cerveau réagit quand quelque chose le frappe."
Clifford Robbins explique comment fonctionnent les commotions cérébrales.

The brain, a vast neuron network

And unlike Jell-O, the brain’s tissue isn’t uniform: it’s made of a network of 90 billion neurons, which relay signals through their long axons to communicate throughout the brain and control our bodies. When impacted, neurons will stretch, and even tear. As they begin to degenerate, they also release toxins, causing the death of other neurons too.
