Neurosurgeons or anyone who knows alot about neurosurgery (not a medical question)

OK so my friend has a friend whos dad is a famous neurosurgeon. I’ve hatched a brilliant and nefarious plot to get him to set up my friend for the punchline of the century without knowing it. But what we need is some really obscure fact about neurosurgery that any neurosurgeon would know but almost no one else would. He needs to casually drop this in conversation for the plan to work. I’m counting on the dopers!

Thanks.

I’m not a neurosurgeon but you can try one of these Dandy-Walker Syndrome, Klippel Feil Syndrome, or the Arnold-Chiari Malformation.

Alternatively, why not mention that there is a lucid interval after the initial traumatic event in many people with a tear of the middle meningeal artery (GROSS PICTURE WARNING).

Homonymous hemianopsia Its a visual field cut due to a very specific type of stroke.
Each eye sees either the left or right half of the visual field. The person often ignores the effected side. Its as though they have only half a body.
