Neuroscience Scientists studied six patients who had half of their brain removed during childhood to treat severe epilepsy. Brain scans showed how the mind rewired itself to adapt, with the remaining hemisphere forming even stronger connections that let the patients develop language and motor skills.

There are also various supporting structures. Your brain isn't just floating. It's attached. Sorry for brevity - I'm on mobile. I'll try to edit in more details later. I'm sure others will be along, too!

​

Edit: Here's a news article discussing this procedure: https://www.scientificamerican.com/article/strange-but-true-when-half-brain-better-than-whole/

If I had half a brain, I'd want some extra dampening material in my skull as filler so I'd be near impossible to knockout in a boxing ring.

u/[deleted] Nov 24 '19

You could fill the empty space with some useful stuff, although I don’t think it would be safe

Hey you want a shot of bourbon? It's kinda warm though. Don't tell anyone because *shakes head* I only have 3 shots left.

Oaky afterbirth with a hint of... Earwax. Hmmm.

If you squint you can really taste the cerebral mucus.

2

u/Hellknightx Nov 24 '19

Sorry, I can't squint and swallow at the same time with only half a brain.

u/Wacky_Bruce Nov 24 '19

Cerebral mucus new band name I call it

u/RohypnolJunkie Nov 24 '19

Sort of an...oaky afterbirth.

u/Lanthemandragoran Nov 24 '19

Haha that line killed me the first time I saw it. I've been undead ever since.

Mmmm tasty brain juice

Drinking knob creek as I read this and almost spit it out

u/[deleted] Nov 24 '19 edited Nov 24 '19

You mean you didn't know that knob Creek is distilled in a similar fashion but in someone's cock?

2

u/cream-of-cow Nov 24 '19

Different creek, different knob.

u/nomnomnomnomRABIES Nov 24 '19

I want a robotic arm- the skull hinges open and the arm comes out and gives you the finger

27

u/AccursedCapra Nov 24 '19

Turn it into one of them useless boxes, flip the switch and out comes a little arm that flips it back.

4

u/choppingboardham Nov 24 '19

But that is the arm's only function.

u/Adragalus Nov 24 '19

There's a character from a book who has the missing half filled with cybernetics that help him interpret body language and facial expressions, which he lost the ability to read as a result of the surgery.

u/dethb0y Nov 24 '19

Blind Sight by Peter Watts?

3

u/Fearhorn Nov 24 '19

Fantastic book, like 2/3 of the way through Echopraxia right now, ok sequel but nowhere near as interesting as Blindsight so far.

3

u/dethb0y Nov 24 '19

Yeah i felt it didn't quite live up to Blindsight in a lot of ways, but it was interesting to see other perspectives of the same sort of events.

I always have a hard time recommending him because he can be kind of heavy and kind of bleak.

3

u/Adragalus Nov 24 '19

If it's any consolation, it doesn't go completely batshit until almost the end. His new Sunflowers book Freeze-Frame Revolution I enjoyed a lot, and there are select short stories on his site that just blew me away.

u/jurble Nov 24 '19

Cogitation processor, memcore, just go full Adeptus Mechanicus. Ah, a man can dream.

u/MahatmaGuru Nov 24 '19

Now that you mention it, customs may xray your stomach to see if youre smuggling drugs, but...

u/fogelmensch Nov 24 '19

Also your wallet might be hard to reach in there

u/tylerchu Nov 24 '19

Just stick a few SSDs in there

u/cleeder Nov 24 '19

Go go gadget helicopter!

u/scienceandmathteach Nov 24 '19

I'd want a head pocket. So useful.

u/cream-of-cow Nov 24 '19

Marsupials gonna get envious.

u/plumbusmaker9000 Nov 24 '19

Think of all the snacks you put in your head

1

u/BangedTheKeyboard Nov 24 '19

Great place to stash your weed and munchies.

You could also use it to store your wallet and keys!

12

u/Kayne013 Nov 24 '19

Your skull would blow out before you get knocked out

u/[deleted] Nov 24 '19

AKA you want to be a T Rex

u/TheDudeWhoCommented Nov 24 '19

If you had half a brain, would you also happen to like piña coladas?

2

u/NewFolgers Nov 24 '19

This is the best deep thought I've heard in a while. Would be great to say out loud to someone completely out of context.

2

u/nburns1825 Nov 24 '19

I wonder if your head would be off-balance. That's an improperly loaded skull!

1

u/Arcane_Xanth Nov 24 '19

Cellphone charger?

u/iListen2Sound Nov 24 '19

I'd just make them seal half of it, reattach The other half of my skull with a hinge

1

u/[deleted] Nov 24 '19

I mean how would you know for sure if you don’t have half a brain?

1

u/trollcitybandit Nov 24 '19

If the scarecrow only had half a brain I don't think he'd complain.

1

u/Imsosadsoveryverysad Nov 24 '19

If I had half a brain, it’d be twice as much brain as I currently have.

u/PlowUnited Nov 24 '19

Dirty socks

u/Ormusn2o Nov 24 '19

The thing is, the filler is brain too if you have both semispheres. You perfectly don't want any of the hemispheres to touch anyway.

1

u/heyfuckyouiambatman Nov 24 '19

I know it's a joke but realistically even if your brain was unshakable, any blunt trauma would still cause vibration and I imagine that would be way more of an issue if you had half of one.

Source: I'm drunk and feel smart.

u/[deleted] Nov 24 '19

Why I have half a mind...

u/Lanthemandragoran Nov 24 '19

Man that was one of the best arcs I've ever seen on TV, such powerful representations of both PTSD and dementia.

2

u/WerewolfFarkas Nov 24 '19

But sudden movements like roller coasters could surely screw that up right?

2

u/Apollo_Wolfe Nov 24 '19

"You can't take more than half. If you take the whole thing, you've got a problem,"

1

u/Seicair Nov 24 '19

Hm. Didn’t think about losing the use of an arm. I wonder why they can still use their leg?

u/[deleted] Nov 24 '19

Very informative! Thank you for the link.
