I cannot get this out of my head. I need an answer. What if you sit him down and tell him "write down what you're thinking right now" to the side that cannot communicate with words. WHY HAS THIS NOT BEEN DONE IT WILL TELL EVERYTHING. The right hemisphere clearly knows how to understand words. It knows how to follow commands. That must mean it can think. I need to know this. This can tell you if it's a separate person. Maybe even answer religious questions about the soul WHY HAS NO ONE DONE THIS?!?!

@edileox7082 12 күн бұрын

think of it as a subconscious (its not one, but its easier to explain it this way). One woman was shown video footage of a fire PSA, and it showed a man being pushed into a fire. because her "subconscious" couldn't communicate what it saw, she got freaked out and her conscious mind told the man with her that she was scared, and that he needed to stop doing to her whatever he was doing. basically, you are indeed seeing and processing everything, always. another way to think of it is when you flip your eraser around to erase something. when you do so, do you think word for word "oops a mistake, better erase" or do you simply move to erase it quickly as not to linger forever to erase one little thing? chances are, you simply see the mistake and fix it without too much further thought. its similar to that. essentially, it isn't two different minds, its one mind communicating different things to different parts. the video makes it come off as more complex because they are using extremely specific examples with rules in place the individual has to follow in order to display how the brain is working. asking the other brain what its thinking would be moot, it would simply say "im thinking about the studies and images being shown"

@@edileox7082 There's a lot of evidence that supports the idea of the brains being independent in terms of preference and individuality. In split-brain studies, each hemisphere can perform independent actions, even ones that conflict with the other side's goals. This happens a lot in these studies, for example, in some cases, a person's right hand (controlled by the left hemisphere) might pick up a shirt while their left hand (controlled by the right hemisphere) puts it down, as if the two sides disagree. This isn't just a "subconscious reaction" but rather suggests that each hemisphere has its own “intentions” when separated. Another thing that supports this is neuroscientists like Roger Sperry and Michael Gazzaniga have proven that each hemisphere can have its own set of memories, preferences, and perceptions when isolated. So if you were to ask what the person's favorite color was, each side COULD and HAS picked something different in these trials.

there are times where I’m thinking of a convo or am “narrating” in my head while I’m having a conversations with someone and then what I’m thinking or narrating will escape into my words but it’s something I never meant to say it was just something I was thinking of saying at a later time or that makes sense lol but would that be an example of this or when I am in the kitchen someone will tell me can you grab this while I’m in the process of grabbing my item or whatever it maybe and then my brain goes for the item my coworker asked me for instead of the item I was looking for originally or is that something completely different

@ashtonpangborn7017 4 ай бұрын

I think that's a great way of identifying the right brain cuz its mute and acts completely reactionary. where the left will try to make sense of it like u are doing in this comment r n, and honestly that's so cool and i think since watching this video i will be identifying this a lot more. i would love to do more experiments with it tho, it makes you wonder if there is another being in your head, what if they want to communicate or tell you something but can't because its mute what if you could train this part to be like a kind of 6 sense ie: put your left brain to sleep while your right one does a visual and simple task but than again how simple of a task does it have to be, how smart is your right brain is it just as smart as your left, if so could you work in a job that lets you do complicated tasks like math and science with your left brain asleep. theoretically you can as long as you don't need to talk. imagine a world were you don't have to sleep or worry about a deadline because you can technically go to sleep at anytime and have a separate entity help you out.

because on the screen he's focusing his sight on the cross in the middle of the screen, otherwise his eyes would move to show the picture to both left and right fields in both eyes (like he can do on the paper)

@zecchini466 3 ай бұрын

What I don't understand is the following: both eyes can see the words "bell + music", why would the peripheral vision have sides? If it is true, ok. But, if not, couldn't the man interpreted the "bell + music" as "bell music" (with his left hemisphere) and answered based on this? In that way, the right hemisphere didn't interprete nothing, because "bell + music" was communicated in words. Or the right hemisphere is capable of reading too, but the interpretation still the same as the left hemisphere would do, or even how I would do. "Bell + music" for me is equal as "bell music", following the context that the image options give to me. The only image that nearly represents "bell music" was the church image. *Your observation is a good one. The man could have closed some of his eyes to make the experiment with flashing words. But it also can be a inconsistency in the experiment.

@momotshabalala8258 6 ай бұрын

Wait wait ,at 7:59 he pointed to a word ,does that mean his right brain can understand words just not say them or is it a because he wasn't given a reference to go with the word so he couldn't see it and had to draw them out but when given a ref he can see the word?? But if his right brain and left aren't communicating how could he see the words on the left ?😭

@bogdanpopescu1401 5 ай бұрын

his right brain obviously can understand words, otherwise he could not be able to follow the request to draw what he saw with the left eye; both the request and the image had to be processed by the same hemisphere

@@zecchini466 Thats because the left and right Facialspace is seperate. The nasal part of the Retina crosses in the chiasma opticum to the opposite Site and the lateral part stays on the same site. So everything you see on the left is projected in the right hemisphere and everything you see on the right is on the left. So only one hemisphere sees Bell and the other sees music but since they are not connected the cant put this 2 inforamtions together and it depends which information is used based on the task he has to do: Interpret or sth. else so the dominant Hemisphere for this special task does it, but only with the information it has: The one works with bell and the other with music (hope this is understandable :D)

Absolutely not I mean, sure, if you want to play twinkle twinkle little star with the left hand and für Elise with the right on the piano then go for it, but that's not what music's about and if you found yourself in this scenario you'd realise the need for having a centralised means of synchronising your hands towards a common time signature grossly outweighs the apparent benefit of being able to move them completely indepedent from one another

I think that today it'll be as easy as using headphones with stereo and/or a VR Headset that shows different things to each brain and each answers with the part of the body they control. But drawing/writting might be the cheapest solution.

What bothers me is that they didn't physically separate his fields of vision, like putting a piece of cardboard between his eyes. There is nothing that prevents one eye from seeing what appears on the other side of the screen. It seems to me that the experiment is poorly controlled.

@sodasudi9720 9 ай бұрын

They are making him focus on the plus at the center, thus fixating his right and left visual fields. The right brain receives optic information from both the left and right eyes, but only from the right side of the retina of both eyes, which corresponds to the left visual field, not the left eye

So separating his eyes wouldn't work anyways.
