I work with brains. More specifically, I work with specialized immune-type cells that are native to the brain and what happens to them when the brain is developing under certain stressors. I actually do say..."there's still brain on that..." because it's all part of the job. That gave me a laugh.
I don't see how someone would dislike this video, there must be someone hired to dislike all videos at least once so no videos can have a 100% like rate or something
obviously not, some people just dislike the material. they might have found it boring, or not related to earth, or maybe they subscribe to a weird different theory of the brain behaviour link
Got questions!? Come discuss this video with brain experts on Reddit: www.reddit.com/r/askscience/comments/53oaf7/discussion_minuteearths_newest_youtube_video_on/
that sounds like a question for our experts on reddit right now! www.reddit.com/r/askscience/comments/53oaf7/discussion_minuteearths_newest_youtube_video_on/
If you're talking about visual information, it doesn't look like it can. Damage to the optic chiasm results in a specific type of visual field deficit depending on which nerves were severed. This wouldn't happen if visual information had the alternative route of the corpus callosum. www.ncbi.nlm.nih.gov/books/NBK10912/
i do know that certain types of blindness makes the brain rewire which allows blind people to tell at 80% accuracy where the source of light was coming from, but they where not able to see anything consciously.
I can answer that! If it is completely severed you are 100% blind. But if the central regions are effected you get bitemporal hemiopisa - that is you loose your peripheral vision. Central vision fibers travel through the lateral portions of the chiasma whereas peripheral travel through the central regions. As for re-direction, that will not happen as there are no other connections to the optic nerve.
I'd like to take this opportunity to give a shoutout to David Eagleman's excellet book, Incognito: The Secret Lives of the Brain. It's a great overview of how different parts of the brain interact and come together to create our thoughts.
There's also the complementary idea, namely what kind of behaviour/activity/brain function is really something that is one thing, that exists in a module. This video is great context for understanding the concept of dissociation and double dissociation, which is used to map out that territory. There's a great paper, "Memory, Perception, and the Ventral Visual-Perirhinal-Hippocampal Stream: Thinking Outside of the Boxes", by Bussey & Saksida, 2007. It really made me think hard about the difference in how we talk about the things the brain does, and how much our day to day thinking colours the kinds of questions that we ask. Highly reccomended!
it's kinda told off the tough and branches off from minute phiscyis, why it called that is because the bodies are only in a matter of minutes and not hours.
"Back then scientists had only accepted the idea that we thought with our brains and not with our hearts." - Galen would be spinning in his 1900 year old grave. I love your content MinuteEarth, but that is a SERIOUS historical error.
None of them. The midbrain and diencephalon help integrate the senses with higher cognitive function. And fasiculi connect different regions of the brains. But none of them "know" what areas of the brain do what, they just do what they've evolved to do.
A friend whipped a big ice chunk at my head, and it shattered, with extreme pain and my head shook. I feel really cold now, and I feel like something is pressing on my head.
Right. So the title emphasizes the different parts of the brain. And what I said emphasizes the functions? I am not a native English speaker you see :)
They failed to research that the left and right hemispheres are completely different. The left hemisphere IS LOCALIZED though the right hemisphere is not. The left hemisphere is for language. Broca's aphasia and Wernicke's aphasia are very real and result in the same characteristics. It is CRITICAL to mention that Broca's area is on the LEFT hemisphere. Only VERY FEW have language in the right hemisphere. If a person has a stroke in the left hemisphere, you can look at the brain scan and determine what type of aphasia they will have; either fluent or non-fluent and then determine if they can repeat. Damage to Broca's area prevents a person from being fluent, but they can comprehend better than they can express. Damage to Wernicke's area prevents a person from comprehending, but they are fluent (but not grammatical nor do they make sense). Damage around to Wernicke's area can prevent a person from being able to read and write because those areas are so close together. There was not enough research done to make this video. Sorry.
brain stem=Me thought in the back of the frontal cortex =control my personal belief a soul is in the front of the frontal Cortex, meaning that ppls thoughts never travel that way with an out of reality mindset=hell
I was wondering the same thing. I read about it and apparently his right side of the body became paralyzed. He died 21 years after he's been hospitalized, not a few days as they say in the video. It's a crazy story, you should google it.
lifeincolour09 it is verry fasciniating, makes you wonder doesn't it, what brainmalfunction could have caused this. Especially since his cognitive ability was still present.
tan... tan.... tangent to the curve is equal to the first derivative of the equation
I was about to say that he was probably a mathematician
My brain exploded..tan.tan.tan
Noice.

Hodor... ;'(
***** reference was brilliant too XD
I didn't get the Hodor reference until I read this, brilliant
I can't believe I had to scroll down to the third comment to find this!
HOLD THE DOOR...
"... it still has brains on it."
Yeah.. Was that Emily Graslie? Kinda didn't sound like her..
Nah, they were just paying homage.
YEAAAAAAAAAAHHHH!!!!!!
"[HOLD THE] TAN [DOOR]!"
[I'VE GOT A] TAN!
Too soon. :-(
RIP Walder
azdgariarada
Walder Frey?
Walder is Hodor's real name. No relation to Walder Frey. "Walder" is like the "John" of GoT, very common name.

RIP Walder Frey!
(Rest In Poop)
Than man must be pokemon, since he can say only Tan, hmmm
Tan I choose you!

its a meme now ;)
MinuteEarth ALWAYS still has brains on it.
"Cute! I should go tell Emily about this.... Oh! She's seen it already :P"

I know right? btw I love rick and morty
Lord Harambe Thanks Harambe, that means a lot coming from you
obviously not, some people just dislike the material. they might have found it boring, or not related to earth, or maybe they subscribe to a weird different theory of the brain behaviour link
Thomas Richardson Well yeah I know obviously but I mean they make such good content I am just being dramatic on the internet lol
Got questions!? Come discuss this video with brain experts on Reddit: www.reddit.com/r/askscience/comments/53oaf7/discussion_minuteearths_newest_youtube_video_on/
ok
Great video, and as a left handed person we are known to be in our right minds.......a little brain joke for ya !!!!
hi can you help what would happen if fish blinked would they bump in to stuff and die are live a normal life
I really liked this. I want more videos about brains.
What happens when the optic chiasma is severed? Can traffic be re-directed through the corpus callosum?
that sounds like a question for our experts on reddit right now! www.reddit.com/r/askscience/comments/53oaf7/discussion_minuteearths_newest_youtube_video_on/
I swear Corpus Callosum is that midget from Mad Max: Fury Road.

"how do we know" needs to be a series
one of the videos should be evolution
He'd just got back from holiday and he was really proud of his tan.

I love your channel, one of my favourites, keep it up :)
Tan! TAN!!
Tan?
*Tan*

Mom's Spaghetti
Tan.tan? Tan! Tan tan!
Hodor?
Nice video!I love your videos!
hodor hahahaha jokes
It still has brains in it!
Yay for the Brain Scoop!
Damn, that got DARK at the end
So the "tan" guy is like hodor or something?
yes. and that was even a hordor joke at the end
It still has brains on it!
Hodor???
Minute Earth just Hodor'd us. Is this the new Rick Rolling?
Thankyou MinuteEarth for keeping us informed
HODOR!
Tan-Tescan-Test scan-Do a test scan
seems legit
That "Tan" guy was the original Hodor.
Hodor Hodor
The patient tried to say TANTOR! his name.

all the parts do the same thing: taste delicious
I like the video nonetheless, but why is it on the channel called MinuteEarth?
Because MinuteBiology doesn't exist yet.
Tan
it's kinda told off the tough and branches off from minute phiscyis, why it called that is because the bodies are only in a matter of minutes and not hours.
the tan-guy reminded me of "hodor."
but wait, would he say "do a test scan" in a paris hospital in 1861? :P
He heard it in the future of another timeline, where he didn't die.
Dogizmaster
hodor :|
Hodor
hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor hodor
hodor hodr hodor, hodor?
hodor!
Tan.
thats literally all i could think about
Poor Hodor ;_;
Can you grow neurons and put them in the damaged/removed part so it will grow and redirect/relearn signals?
"Back then scientists had only accepted the idea that we thought with our brains and not with our hearts." - Galen would be spinning in his 1900 year old grave. I love your content MinuteEarth, but that is a SERIOUS historical error.
I still don’t understand why I used to have a fear of normal mushrooms (not toadstools) and dandelions (when the seeds are exposed and look of fluffy)
The thumbnail text is actually really clever.
But what part of the brain knows what parts of the brain do what?
None of them. The midbrain and diencephalon help integrate the senses with higher cognitive function. And fasiculi connect different regions of the brains. But none of them "know" what areas of the brain do what, they just do what they've evolved to do.
I was just making fun of the brain not knowing a lot about itself. I was gonna guess "cerebrum" tho.
Ow! Stop that!!
Damn you made soldiers with shrapnel in their head cute. My soldier with shrapnel in his head looks like he's about to kill a walking nuclear tank.
That hodor reference though
1:04 for all you high school statistics class students
High school.... I just did this in University last semester lol
Trigonometry was The problem...I knew that all along....😂😂😂
hodor noooo
Thank you!
Didn't notice the Hodor reference until the end. It made me chuckle haha
A friend whipped a big ice chunk at my head, and it shattered, with extreme pain and my head shook. I feel really cold now, and I feel like something is pressing on my head.
Loved the HODOR reference
Hodor.
the tan guy was probably just a math student with anxiety issues xD
enjoyed the video, as always, thanks!
Two words: Phineas Gage.
Another two words: Henry Molaison.
A further two words: Clive Wearing.
Nice 'the Brain Scoop' nod. Also, Hodor.
For a second there, I thought this was going to be an epistemology video
BRAINSCOOP
Great video,creative,fun, and great information Thanks
That ending was cold hahahahah
When the square root of -1 came in at 2:35, that immediate thought came into my mind...it must have been imaginary!
his shirt needed to be tanned but the broca's area made him think and say simple words
Tan, tan tan tan tan tan. Tan tan tan tan tan tan, tan tan tan tan tan. Tan tan tan tan?
I have seen a chamber opera based on the story you recommended at the end!
Spoiler alert:
"Hold the door," I believe.
Put up a spoiler alert!!!
:)
Thank you for the reminder o.o
We won't go quietly, the lesion can count on that.
Brainscoop reference! +2 internets!
I have a project due on this very topic due next month, nice timing!
ahahahaha that brainscoop reference!
Can someone tell me why the title of this video is: "Which Parts Of The Brain Do What?" and not "Which Part Of The Brain Does What?"?
Because they decided for the former? Why shouldn't they?
I don't know. Do they mean the same?
They don't mean exactly the same. The latter emphasizes one part of the brain.
Right. So the title emphasizes the different parts of the brain. And what I said emphasizes the functions? I am not a native English speaker you see :)
This is a smart comment chain. I like it.
probably he found answer to sin over cos
War, what is it good for? Understanding the human brains apparently.
TAN! TAN! TAN! nice reference of HODOR!
Don't put people with shrapnel sticking in their heads in mri machines, that's dangerous!
This vid went from 70 views to 170 views in like 15 sec
And now 225
You need to get a girlfriend mate. Something else to occupy your time.
And now 3,352
Nevermind, that's when I started the video.
It's now at 6,296
11,704 now.

still has brains on it!
brain stem=Me
thought in the back of the frontal cortex =control
my personal belief a soul is in the front of the frontal Cortex, meaning that ppls thoughts never travel
that way with an out of reality mindset=hell
The ending is great.
I thought the soldiers were orks with goofy smiles 2:23
this explains why I was always good at math and music, but sucked at english and life lol.
My psychology textbooks lie to me about brain 😶
Tan is the real life Hodor.
Broca's area is typically in the left temporal lobe not the left frontal lobe. Remember kids, don't use CZcams videos for research.
Whith this knowledge I could a hero.
Reminded me of “hold the door”to “hodor” in game of thrones series
A brain studying about a brain
Nice closing line, but I think it's from the wrong Emily.
Corelation turns into correlation, please notice the major typo! (It's actually minor, all you have to do is edit the typo. Lol.)
Hodor!
that outro was mildly terrifying and sad
Another good video!!!
Tan tan tan tan tan. Tan tan, tan tan tan. Tan! Tan tan tan, tan tan. Tan tan tan tan tan tan?
haha that ending
Brains thinking about brains... Whoa.
All people who thought of hodor from GOT, same pinch!☺️
Tan!
Maybe the patient was really excited to be no.10 on a famous youtube video.
couldn't he just write what he meant?
I was wondering the same thing. I read about it and apparently his right side of the body became paralyzed. He died 21 years after he's been hospitalized, not a few days as they say in the video. It's a crazy story, you should google it.
