- Brain damage is usually a bad thing, but sometimes the best option is actually to damage the brain in very specific ways.

Is this the human equivalent of slapping the top of your TV to make it work?
Nope. Slapping (old, CRT type) TVs works by either moving away dust/(dead)insects [so the interruption or soft_short_circuit between metalic parts move away]; or by re-attaching (temporarely) broken contacts that have spread appart (because of termal expansion, corrosion or other impacts).
-> The examples with the "cortical stimulators" is more like a peacemaker.
No, this is better compared to taking the faulty computer and turning it off-and-on again.
the brain recognizes the signals from the stimulation bits as faulty, and so does the biological equivelent of "resetting" that section.
DISCLAIMER: this metaphor is also very flawed. I am not a neurosurgeon. Have a nice day.
It's more like the human equivalent of connecting your computer to a surge protector when you live in a place with lots of lightning storms.
did you try turning it off and on again
Hahaha. 😂
CGP Grey made a video called "you are two" where he talks about side effects off splitting the brain into halves and I think it's really interesting!
Until he wades happily into Dunning-Kruger territory making wide-sweeping generalizations (essentially all based on the oooooooooooold "right brain vs left brain" myth) and flowery assertions that aren't based in anything more solid than philosophical flatulence either ignoring or hilariously ignorant of wholly invalidating details like rare examples of people who unknowingly grow up with a single hemisphere without any side effects, that while some processes can be *more specialized (i.e. not unilaterally specialized)* to one side than another, the ability to name an object vs draw it aren't locked to a single hemisphere, the brain reorganizes itself over time to compensate (though not completely) for deficits, and people survive relatively normally following hemispherectomies rather than completely lose half their personalities or whatever traits commonly ascribed to whichever hemisphere.
@@custos3249 No he doesn't, I'm no sure you understood the video.
@@MakkusuOtaku My bad. I must've missed those days in biopsychology while getting my degrees.
@@custos3249 Yeah, my attendance wasn't so great either.
@@MakkusuOtaku You understand neither sarcasm nor neurobiology. Classic.
I know someone who had surgery a few months ago to install a DBS implant to help with her early-onset Parkinson's. It's really helped her a lot.
Rithene That's good to hear!
Aw, you didn't mention the most interesting side effect of a corpus callosotomy: Alien Hand Syndrome. Due to the reduced communication between brain hemispheres, sometimes one result is that one of the patient's hands can do something different than what their other hand is doing. As in, a totally different task, like if they wanted to play basketball, but their other hand decided to wave at a family member without them intending it to.
Because it's rare
Actually it's even more interesting. Corpus callosotomy seems to divide the consciousness of one person to two. Alien hand syndrome is the least of your problems when you realise you share your body with another entity. Sam Harris describes this in a chapter of his book "Waking Up" and CGPgrey visualizes that in his popular video "you are two"
Man, that's fascinating
Could you do a video on why we get that feeling of being watched? I really want to know why that happens.
Keep making amazing stuff guys.
Another fascinating topic in this category is recent discoveries showing how the brain will route around damaged regions and over time repurpose other regions of the brain to take up those same tasks. Damaging the brain in order to get it to rebuild itself is a very promising treatment angle and potentially much less complex than attempting to directly fix it ourselves. There's a good possibility that this is the mechanism that makes ECT work as well as it does, for example.
If only we could find ways to make the brain regenerate. That would be super awesome.
Feynstein 100 or prevent brain damage from happening
+Celina k That too but the nature of randomness is that no matter ho much you try to prevent something, occasionally it does happen :/
There are. Or atleast there are ways to promote new brain cell growth. Sandra Thuret does a TED talk on it. I HIGHLY recommend it! :)
+Jamie Mann I think I've watched that video. But iirc, new cells are only generated in the hippocampus. If any of the other parts get damaged, then there's pretty much no way to repair them.
Neuroplasticity
Fantastic and Informative video thanks Brit (And the rest of the SciShow team)!
I'm loving the animations, your animator is good.
There's another more extreme form of intervention for conditions like severe epilepsy beyond severing the corpus callosum - a hemispherectomy. Where half the cerebrum is removed.
It's definitely a big cost/benefits sort of procedure (rarely medically necessary, but cases exist). Though neuroplasticity generally never completely goes away - it's best indicated in very young children (who don't otherwise respond to less invasive treatments) because their brains will be better able to rewire around the missing tissue.
I'm surprised she didn't talk about the guy with severe OCD that shot himself in the head, he survived and discovered that his OCD was gone.
I swear that half the reason I watch is to see what awesome t-shirt she's got on today.
She looks amazing as well!
If the corpus callosum is severed then the 2 hemispheres can't directly communicate, but they can still wave at each other, right? Isn't that what "brain waves" are?
I can't tell if your being serious?
big mike
LOL If you ever see a comment of mine it's 99% likely I am joking ^_^
big mike,
I've seen enough of Therion's comments to realize that he's just trying to make puns.
Beskamir
Trying? More like *pun*tificating!
Sorry, but this one is one of your worst puns ever :(
So to protecc, you must also attacc...

I keep getting sleep mattress and pillow ads on these! They're actually really interesting!
My brain is ready! In fact it is the perfect specimen! Now heal me!

I have OCD and ADHD and anxiety and depression but I smoke a lot of weed which helps soooooo much. I'm able to focus and be productive. Marijuana also treats seizures the best.
Isn't split brain surgery a cause for alien arm syndrome? Just wondering if information has changed since last time heard about it.
For males, it forever isolate "one person" by removing their ability to speak or even understand language (females _usually_ develop two independent talking centers).
Still able to comunicate their basic feelings with hand gestures and other actions, but to never sharing their ideas/complex_opinions with their other half or third parties.
wrathXzoul yeah
Argamis (SilverComet) yeah, female speech is often (but not always) more bilateral than in males, however it is also possible for males to have their Brocas/Wernicke's areas in their right hemispheres, or even bilateral speech centers. This possiblity is much higher in left handed males (and females).
I am talking about "male brains" (statistically speaking for the great majority of population, from with a small percentage of cases are treated this way).
The factors that may make a female to NOT develope bilateral speech (or a male to DO so) are completely unrelated with the posibility of developing a disease that requires isolating their brain hemispheres.
THEN -> The chance of ever finding a male who has his two minds able to use their vocal cords to TALK [not just to speak, but to comunicate on a high level] is as small as getting an intersex requiring the operation.
wrathXzoul limme Guess
Life noggin?
To Heal an Omelette, Sometimes We Need to Break a Few Brains; gotcha
1:56 Now, I dunno 'bout math or all dat fancy shtick, but unless they mean 64% = 40% + 24% here, it seems them doctors had a case of 4% inflation
No more drop seizures is certainly a decrease, so I'd say the 40% is a subset of the 64%. Which implies that the procedure didn't make any difference (or maybe even made things worse) in 36% of cases.
Which implies they didn't make such a good job with the script; oh well, you know what they say: if you can't beat lemonade, make some life with it
When life gives you lemons, lobotomize your patient.
Or the lemons
I'm surprised you missed the big side effect of severing the corpus callosum...alien hand syndrom.
"2013 study: 40% of the patients had no more drop seizures after surgery and 64% had the frequency reduced." That's 104% total... unless the 64% is for seizures in general and not specifically drop seizures?
I wonder what procedure will cure OCD. Obsessive Chicken Disorder.
Gravijta
Rinse the chicken obsessed brain and pat dry. In a large bowl, beat the eggs and set aside. Coat the brain in egg and dredge in flour, shaking off any excess. Heat 1 inch of oil to 375° in a large frying pan. Gently place the brain in the hot oil and fry on both sides until crispy and cooked through, 10 to 15 minutes on each side.
Master Therion
Mmmm... Kentucky Fried Brain! :F
I think all the researchers are done studying that. It's just too exhausting and they're all fried.
Colonelectomy
Gravijta gib chimken
Meanwhile in Argentina, patients are treated with homeopathy and psychoanalysis...
Percussive maintenance works on people too?
Deep brain stimulation is not an example of "damaging" the brain. This video could use an update.
I damaged my corpus callosum, and I haven't had any problems with seizures since! But, to be fair, I didn't have any problems with seizures before...
Brit Garner is a dime 👌
Do they have a surgery that helps for people with ADHD?
That's the same thing my bartender tells me when I'm feeling down
Hey the host has lost some weight! Well done, host, you are great!
felx tape it
NOW THAT’S A LOT OF DAMAGE
sawed a brain in half
If you lose your mind, Break your brain!
Is there anything like DBS for Schizophrenia?
rogerdotlee i would hope not. It sounds pretty invasive and i wouldnt want to be forced into that should my schizophrenia become bad enough to the point where i cant make my own decisions
Yes, but it's in the very early stages of trials though shows promise and, like for everything else, the rare times it's been used it's only been for severe conditions. Also, unlike Sup seems to think, it's not ethical to use it on someone unless they're able to consent.
If I put music in my brain it will heal i watch it a few minutes and it says music heals it and a 8 hour of sleep
hmmm what if severe anxiety is a form of OCD? if true Deep brain stimulation could also help with that ?
This is only my oppinion, so take it with a spoon of salt:
Isn't severing the two hemispheres like splitting a persons consciousnes in half? I mean both halves don't communicate with each other. Like at all.
I don't think a hand arbitrarily picking something up, while you want to do something completely different, can be called coordination problems.
I can see this might help with extreme epilepsy and never would (or even could xD) deny a person in need such treatment, but imho it's not a definite solution.
I could imagine reconnecting the severed nerves might be even harder.
pretty much, in 100 years we'll probably discover a much better and more effective way to treat seizures and we'll look back at corpus callosotomy like we look back at bloodletting nowadays
So my brain damage is a good thing? =D
How long do you think it's gonna take humanity to look at the ways we do brain surgery and think about how barbaric our surgerys are?
1. Get brain uploading tech secure, reliable & good_enough.
2. Set automatic_shooting to the brain once the "checksum" of the copy is ok.
3. "Boot up" the digital copy of the human.
4. Let them "talk" (think) about barbarism.
Maybe I should've said used to be. We look at lobotomies now and think, "The horror", but lobotomies were the cutting edge brain surgery for a long time.
bold of you to assume I have a brain
These still seem pretty brutal
We need stem cells for neurons. And then a way to get them where you want.
*_Dope a meme_*
CGP Grey's 'You are Two' ftw 😏🤙
Granted, they hit the technical side of things much more-so here, but ... meh 🙃
Is it safe?.... IS IT SAFE?..... HAHAHAHAHA!
Interestingly I read a bbc article about an obsessed woman who lost weight after getting deep brain stimulation (for unrelated reasons).
I wonder if in a couple hundred years we will consider this totally barbaric too?
1:02 dont you have 2 synced consciousness? can you still argue with yourself? and can they become unsyced and lead to schizophrenia?
No
No more ice picks to the brain through the eye socket?
First Cynic
hopefully
The title is very misleading
CBD oil could of saved those people having seizures from having to get that procedure, too bad it's still pretty difficult to get medical cannabis
shadowthetwisted +
**facepalm** No. Just no.
They put electrodes in people's brains? Those are big Pokemon though. How do you make them fit?
The real fun will start when they start doing this scrappy stuff to people with mild adhd or depression. Open those cans up, doc!
OoOo ShIiIet!
I got brain damage from reading the title
What could people mean when they say they have a "third eye" - are they talking about the pineal gland (thought to be a remnant of a literal light sensing organ) or perhaps areas of the brain like the ventro medial prefrontal cortex that (I think?) becomes active during R.E.M. sleep, or maybe just an internal awareness in general?
2:35 ACC = Air Conditioning Center, obviously.
A corpus callosotomy can also cause "Alien Hand Syndrome" if I'm not mistaken.
I get it, it's like the guy who got a railway spike through his skull right? anybody?
Wat? Phineas Gage?
Not really like Phineas Gage, he had no issues before the pike, but after it damaged his frontal cortex, he became an emotional, angry person without any impulse control. His case is much more typical of ordinary brain damage - an ordinarily functioning brain becomes disfunctional.
Danielle Spargo yeah I was wondering who they were talking about lol
Brit has a location tattooed on her arm, what does it mean? Is it her home? School?
Brit Garner is genuinely hot
I agree 1000%.
I thought I was the only one, like she wears literally zero make up and still looks really good
I hypothesize that the more you watch a mildly pleasant face and increasingly associate it with positive things, the more you perceive it as beautiful. The "Her beauty grows on you" effect. When I saw her the first time I thought - what an ordinary face and (ahem) healthy (ahem) woman. Today, after watching about 20 videos, I agree with you, she's pretty.
(OR maybe it's me OR you know, maybe she did something - lose/gain weight, eat better, whatever)
Also, I hope I did not offend her, I was talking about changes in *my* perceptions. I have also observed that I grow to like mildly pretty faces over time as long as they are smart or happy or affable, whereas I get tired of watching a really pretty face after some time. Too much prettiness is a thing, IMO. Jennifer Connelly or Emma Watson would be examples of too pretty and not openly friendly. Scishow must have a video on this.
Time for research.
I'd try medical marijuana before trying irreversible brain damage surgery.
Pshh, carefully
Is that why transorbital lobotomy sometimes worked a little bit
ACC
Isn’t this called Reverse psychology?
I don't like these procedures being called "healing". For starters, it's clear that these diseases have causes that are not yet understood, which may be not even be neurological (inflammation and inmunity in ocd, etc), but second, it doesn't take much imagination to see that cutting the main communication path of the hemispheres is a far cry from taking out the appendix, or doing injury debridement. The video tries to pitch the concept as a positive one, but to be honest I find it rather depressing, and a bit miopic.
these treatments is basically modern bloodletting, we have no idea if it works or why it works and have no idea what causes it
Same.
Or you could just eat a Ketogenic diet and legalize CBD oil for Epilepsy and Parkinsons...
Myew the Cat
Preventive care is looked down on too
how could you talk about corpus collosotomy and NOT talk about Split brain syndrome!?
We may have come a long way, but surgery on the brain for psychological problems is still barbaric.
How about you stick to delivering pizzas and leave neuropsychology and neurosurgery to the experts? Either that or just don't seek medical treatment for any tumors, new brain damage, or other condition such as Alzheimer's or Parkinson's. Wouldn't want any of that barbarism to be wasted.
