If you ever come across a skull without an incision line, you can be damn sure there’s a brain in there.
False. If the flesh covering the skull has decayed there’s a good chance the brain tissue has also decomposed or been eaten by insects.
Also it’s called craniotomy or possibly osteotomy not an “incision”.
Depends on the age of the skeleton and the environment doesn’t it? The brain cavity isn’t 100% sealed. There’s openings for optic nerves, blood vessels, spinal cord, etc.
There’s a guy named Bill Bass that you might enjoy reading about. He has some books about the ‘body farm’ in Tennessee, where they study body decomposition in different situations.
I googled it for us, guys:
You can, without much work actually, remove the brain through the cervical hole (the hole the spine is “connected” to)
