"What happens during a concussion?
From a biomechanical perspective, a concussion occurs when the head experiences an external impact. Since the skull is very stiff and the brain has inertia, the skull moves immediately while the brain initially remains in its original position. The brain eventually catching up with the skull’s motion.
In straight-line, or translational, impacts, the skull compresses the brain at the point of contact, creating localized positive pressure. At the same time, on the opposite side of the brain, the skull’s movement creates negative pressure.
In rotational impacts — when the head is spun — the skull’s movement causes shear forces within the brain tissue, causing it to deform. Since the brain consists of different regions responsible for different functions, this tissue deformation can affect specific brain functional regions, leading to the range of symptoms associated with concussion."
