Does bumping your head kill brain cells?

When a person is hit in the head, the brain bounces back and forth in the skull, the researchers explain, which can lead to damaged brain cells and even damage to surrounding tissue. Such an impact can break nerve fibers called axons or connective cell tissue called synapses.

Can a head injury make you smarter?

Treffert, now retired from the University of Wisconsin School of Medicine, diagnosed Amato with “acquired savant syndrome.” In the 30 or so known cases, ordinary people who suffer brain trauma suddenly develop almost-superhuman new abilities: artistic brilliance, mathematical mastery, photographic memory.

These structures include the thalamus, which lies deep within the center of your brain, and the hippocampal formations, which are situated within the temporal lobes of your brain.

A hard hit that doesn’t cause bleeding or an opening in your skull could be a closed brain injury. An open brain injury is when an object penetrates the skull and goes into your brain.
