What's Most scary is, that there are cases where one hand tried to choke the patient or tried to sabotage the other hand. Imagine being fucking scared that the consciuosness, you share the body but can't communicate with, tries to harm you.
Yes so true. There are even cases where the hand will slap food or clothes out of the persons other hand. Even one case where the woman went to the doctors office crying and her hand started unbottoning her shirt in front of people. Its been recorded that the "other" hand at times has been quite mean/lack social aspects. Makes me wonder about certain mental health issues, maybe the other side is acting out more in those cases? Maybe in certain brains its more dominant?
@Meriysi two years late to this but: I can't blame it for being bitter. Imagine you were locked in a body with no way to communicate, and just purely a passenger in your own body? You'd turn real dark real fast.
Imagine if you were this guy. You could literally have a conversation with the other version of yourself, asking: "draw me a picture of how you feel", or even more interesting: "how does it feel to not be able to speak?"
Idk, I think missing half of the brain might make asking existential questions more difficult. It may not occur to the left brain to ask the right brain how it feels not to be able to speak
No these studies are quite true. This is not the unscientific "Right-sided/Left-sided" argument. Severing the Corpus Callosum stops left-right communication. This is not about Artistic talent and personality. In a healthier individual the two side communicate. This man is neither right nor left "brained", but rather split brained. Completely different. I would urge you to look into this in great detail. Perhaps some peer reviewed material. It's incredibly interesting :)
I was drawn to this video from a book 'touching a nerve' and from what I read there, Lower structures such as those in the thalsmus and vrainstemm are not seperatedm thus the qualification 'somewhate independent'
for anyone interested... as an a level psychology student, i found that split-brain patients cannot describe what they see in their left visual field because language is lateralised in the left hemisphere however the left visual field is controlled by the right hemisphere. so when split-brain patients see something in their left visual field, the information in the right hemisphere is unable to be transferred to the left hemisphere which is associated with language. that is why they can still draw it even though they cannot say what they saw. i hope that makes sense 😂
CPA here. I sill remember watching this in Psyc 101. Who says those non-major classes are useless. In my Psyc class we also had a professor speak who was doing the most extensive twin study to date. The professor was David Lykken (look him up). He shared some of his preliminary findings on his study of some 1300 sets of twins. Thoroughly fascinating. I still remember everything in this class but can't recall interest capitalization accounting since I took the final.
Is your corpus callosum severed? kek:D Cuz that'd be the only thing prohibiting your hemispheres from communicating with each other non-verbally, guess you'd need speech otherwise.
that's uh...not how that works. language and speech are both in the left brain. you can't think (in words at least) with your right brain, so it can't perceive communication. You're probably just actually talking to yourself.
@@ryn7782 if someone was split brained, could left brain talk out load to the right brain and have the right brain talk back by writing? or can right brain not understand language?
I would give my subconscious side a name just for the heck of it; so when something weird happens that your subconscious did, you can just go “Damn it Jerry!” 😂
Your always "2 People" but your right brain always works to help your left, but when they're split they can't work together like they used to. Its like having 2 conciseness. At least that's what I think happens, its a abnormal thought to see yourself as 2 people, or 1 person made of trillions of cells that are all individually alive.
If you say you're 2 people because you have to parts to your brain, then you must say you are a ton of different people because your brain consists of many many different parts working together. I think you could only argue that you are 2 people if you have a split brain
This is mad. this could also explain how I've "known" things in the past despite the fact I have no recollection of actually seeing them etc. SO interesting !!!!
Are you split brained though?This experiment is aimed at split brained people not people who are capable of using both sides of their brain-aka most people.don’t trust my word for it though I’m just saying what Im being thought in gcse’s
I would give my subconscious side a name just for the heck of it; so when something weird happens that you subconscious did you can just go “Damn it Jerry!” 😂
I wonder how this all relates to dexterity and left-handedness. Maybe these experiments would contain slightly different results or just some additional interesting information when done on a left-handed person
i know that vision depth is partially made in our minds by having our brains compile slightly different pictures each of our eyes give. Do split brain patients lose their ability to see that depth?
is it just me? i kinda related to this. when they give 2 pictures at the same time, i can name the pict on the right immediately. but it takes time for me to name the pict on left side
How does he define the 'disconnected' half? I mean, they are both disconnected from each other. It isn't that one is 'more' disconnected than the other, or is it?
I would hypothesize that it would be the same, unless there's something fundamentally different about processing language from right to left as opposed to left to right. Keep in mind that lesions to the left hemisphere affect not only reading but also speech. The idea is that the words on the screen to the right of the dot are processed by the right eye (which goes directly to the left hemisphere) and language seems to be left-lateralized so he has no trouble processing those words. However, words seen by the left eye (goes directly to the right hemisphere) and with a severed corpus collosum is incapable of travelling to the left side where language is processed, so he's unable to vocalize it. I don't think it has anything to do with the direction in which words are processed, lol
+Uli Rip It would be the same because the Broca's and Wernicke's area (what the brain uses to process and partly to speak) are both located in the left hemisphere in the brain
so once the fibers are cut does he become 2 people but since one side is mute he could never talk to his other side? does that mean he can talk to his other concious by asking a question while the other one draws? fuuuuuuuuuuuuu so many questions. why did I watch this at 1130pm?
My daughter (rare chromosome deletion) struggled severely in school. My daughter is extremely developmentally delayed though her Corpus Callosum is intact. I found about Diannecraft.org ( who researched this Roger Sperry). I implemented her methods on how to teach a right brain dominate child (when I pulled her out to homeschool). I got results from day one. My daughter was given a 47 IQ by the school psch. because they used "evidence based testing". I found that when using techniques that engage the right hemisphere everything changed and not only could she learn reading and math facts, she could retain them. I am not an educated mom (formally) but I fully buy into this "theory". I encourage all of you who are in education really research this and apply it. It changed everything for my daughter! The use of pictures, emotion, color, music ect plays a huge role in we right brain dominant people for learning. Sperry's research advances our modern way of education. Sadly, very few therapist, specialists (including the school Pschologists), and teachers don't know a thing about this topic. It's truly fascinating.
one of the main questions I had for any of her specialists was why can Shelby point to an object when asked to find "the red ball" but when I held a red ball Shelby was unable to say what it was. This isn't uncommon in education when you ask a child to name the letter or word. If there is a right/left hemisphere issue..this is one of the common issues. Because of this split brain research I was able to understand that it's related directly to this and why I use the techniques I do.
right hand = left brain which didnt see the thing they wanted him to draw so if they asked him to use his right hand he couldn't draw anything. its freaky

No , he can't
Even though his brain is split, he still has one mind and one personality .
I'm here because CGP Grey made sure I wouldn't sleep tonight.

Yup
One of the most amazing studies ever done.
exactly
"A saw"
"What did you draw that for?"
"I don't know" xDD
why am i walking in this room , i don't know
that's kind of the whole point of the video
Finally a comment not mention CGP GREY

It’s creepy, he knows what he saw but he can’t say it because the side of the brain that can speak didn’t see it, but the side that can draw did

It's weird that no one ever ask the patient: "Do you feel like 2 persons or one person ?"

i know that vision depth is partially made in our minds by having our brains compile slightly different pictures each of our eyes give. Do split brain patients lose their ability to see that depth?
No, both eyes still go to both hemispheres so stereoscopy isn’t lost. the left half of space goes to the right hemisphere (not the left eye)
