In traumatic brain injury terminology, where does a coup injury occur?

Explanation:
In a head injury, a coup injury happens at the point of contact—the part of the brain that directly hits the inside of the skull when the head is struck. The brain’s inertia makes it slam into the skull on that side, causing localized contusion and bleeding there. The opposite side can be affected too, but that’s a contrecoup injury from the brain rebounding after impact. So the coup injury is defined by its location at the site of impact, not the opposite side, not the spinal cord, and it isn’t restricted to any age group.
