My dad knew someone who had a reinforcing steel bar stuck into the middle of his head; The bar entered is mouth and exited in the middle of the top of his skill. After that, the guy was noticeably smarter but also more irascible. My dad theory was that the healing of the brain raised the number of synapses and ridges[1] in the damaged part of the brain (which in this case was right between the two cerebral hemispheres). Albert Einstein's brain had four ridges instead of three.

Wait, there's a modern-day Phineas Gage, and your dad knew him personally?
