Because your brain has no pain receptors, brain surgery is sometimes performed while the patient is awake (and often even talking).
It sounds like something from a horror film, but keeping the patient awake and responsive during brain surgery can actually be a much safer way to operate because the surgeons can ensure they're not causing any significant damage. Still, it's a pretty scary thought.
I should know I'm a surgical tech.
So, you're semi awake and rebelling against the government? lol I know it's just a typo and that you meant to type "sedation", but the thought of "sedition" that you don't remember was too funny to pass up! It's a shame that there's no way we can go back and change our errors. Heaven knows I'm made my share and then notice it when it's too late!
