BANG YOUR HEAD....for brain wrinkles.

Wired into the Brain

However, it turns out all those crevices and crenelations actually help prevent damage.

Other than packing a large surface area into a tiny space, the crinkles absorbs some of the shock from banging your head on the desk, being in a mosh pit, or one mean bar fight. Researchers discovered this through computer models of the brain, which in this case, smooth vs. wrinkled. In the smooth layout, every part of the brain was more susceptible to damage.
