Hail hydra!
Source of brain interconnections picture please. 0:18
2:00 Neuroscience makes a distinction between the brain (physical machinery; hardware) and the mind (metaphysical manifestation; software). It is the difference between the concept of “two” and the reality of “two apples.”
@Quanta Magazine This video gave a cool idea. I saw a vid which said squid change color as camouflage & when they go to sleep they change color & it seems it may be because it's dreaming (similar to how a sleeping dog makes small woof noises). So we HAVE TO MATE HYDRAS WITH SQUID! We have to make hydrasquid that have no brains but change colour when they sleep. This could prove that YOU DON'T NEED A BRAIN TO HAVE DREAMS. Which would indicate consciousness isn't caused by the brain!
@@asmadali-bump, also looking for this
with the current acceleration of Breakthroughs in science, I wish this was like a monthly thing it would be awesome to get updated by these great videos.
Sleep allows greater solution space in the 'ambiguity simulations' for subconsciius problem solving by taking the body 'offline'
This time includes delicate repair and maint' ?
@@benjaminpeljo4874 true, less definitive inputs into the brain would allow room for more variables to be adjusted on the subconscious level.
I agree. I'm always trying to update myself on breakthroughs in science but I find it really hard and time-consuming to do so. Does anyone knows the best way to be able to do that in a relatively quick way? I always end up drowned in huge amounts of information, with an infinite amount of new researches and new discoveries in front of my eyes, which is not something I have time do do now. So how can I know what's more importante without having to dig thorough that much information?

Truly interesting to learn that sleep isn't restricted to organisms with a brain.
But the real question is: Do Androids Dream of Electric Sheep?
@@smithwillnot I'm aware that that's some reference but if you want my opinion to it as a question then I'd say androids won't sleep in the same way humans do. If at all.
They might hypothetically sleep but there would no reason for dreams. Dreams are proven to be at least an evolutionary trait to help beings capable memorizing to go through recent events and "catalog" or rehearse the most important ones.
A robot would simply have one's and zero's to describe everything and it wouldn't need a reason to rethink past events as it's memory would always exist in it's original form of one's and zero's. It's always the same state as it was the moment that information was inputted.
Human memories change over time and we create false memories out of thin air and we question the legitimacy of old unimportant memories because our memories are more complex. Dreams help in that regard.
I'm fully aware a lot of different animals dream but just using humans as a comparison.
@@t3h384 Isn’t it possible that an artificial intelligence could ‘dream’, in the sense that it might run simulations while in a less active mode? (in order to better predict how the world works and how to accomplish its goals based on what it has learned while active)
@@senseofmindshow I have no idea. You're talking about a thing that would be only reasonable hundreds or thousands of years into the future and even then it would have no practical usage even if it was developed to the machine as a function. If it was to run a simulation then it should run that simulation at full power instead of repeating known knowledge in a random chaotic way.
If the point of sleep for that android was to recharge some function like battery recharging or cooling down internal components for example or whatever else, there would be little incentive to implement a "use processing power to think about weird scenarios while restoring processing functionality" as it would be counterintuitive. As I mentioned earlier a machine remembers everything clearly with 100% accuracy as long as it's functioning correctly, so there is no reason to try to enforce these memories as they simply exist in a stable form at all times. A 1 doesn't change from 1 to 0 by itself unlike how memories do in humans.
I speculate that humans (and other animals) are able to use their brain functions in a minor way which allows us to dream during sleep because the processing power of the brain would be wasted during any sleeping period if it's was simply in an idle state. Our brains are still active during sleep as unlike a machine our brains aren't reliant on an input of electricity. Our brains run on energy that we ourselves generate through chemical processes. If a machine had unlimited power or was plugged into a source of power it wouldn't need to conserve it's usage of electricity by restricting functions.
Well, maybe a miner robot wouldn't dream, but what about a writer robot? Couldn't it "dream" about possible stories while it isn't writing?

I agree! They have such an appealing presentation style, blending animations with expert testimonial with old videos of relevant scientific equipment and experiments.
Quanta Magazine always does a brilliant job at condensing scientific discoveries for a wider audience. I love what you do.

This is basically a collective of human minds trying to understand themselves
I’ve been keeping my eyes on my subscriptions just in case Quanta Magazine posts this year’s science break through and it’s finally here! Great episode as usual, I’m also excited for the maths and physics ones!
And thank you Quanta Magazine for your great work!
Regarding sleep and metabolism, there's already good evidence of that being the case with various endocrine functions related to metabolism being affected by sleep disorders like sleep apnea and narcolepsy.
The functional systems model of the brain has also been an emerging conceptualization for a while now and loosely touches on the artificial distinction between neurology and psychiatry.
oooh
We are programmed meat robots inside a Matrix , If you look at the function of all the organs of the body, including the brain, you will find that all the organs of the body have an automatic function, including heart rate, gastrointestinal tract and blood flow, and brain function! Now, if we assume that there is free will and that we are the product of this process, we must be able to explain how, as consciousness, 100 billion neurons interact with each other to produce a thought, in fact no human knows what is going on inside their brain When a thought is produced, the only thing we understand from the thought and what is produced inside our brain is the image and sound that the brain produces, the brain automatically adds our thoughts to our vision! Thinking is like a transparent curtain that adds an extra layer of information to our vision, we see our thoughts but they do not exist in front of us! It is the human ability to see things that do not exist outside of the human body in the Matrix ! The body-mind problem (Illusion of freewill) occurs in the humans when the nervous system get contracted, when this happens the thought process automatically begins to think! And since most people have more or less nervous system contractions, they have this extra thought in mind. ! And in the long run, these thoughts almost become an additional operating system, and it decides for itself and gets the person in trouble! This extra operating system is the same 'I' that everyone has but does not have an external existence. If the nervous system calms down, this extra thought process automatically stops when this 'I' or visual curtain is removed, awareness and Understanding is not of the body, consciousness in the human form it sees itself as somebody and it is separate from the function of the body! The human body is essentially part of nature or simulation, and we experience the world as consciousness through a mediator who is our body! In this simulation, everything is pre-planned, because all human beings are part of the simulation, and in fact, in this simulation, there is really no one, except a consciousness and a running simulation!
All thoughts are extra thoughts, because life is a predetermined simulation! People get lost is their own story and this makes different level of consciousness in the societies, and somehow people at some level get stuck or programmed and they live with it, that’s why a small group of people are controlling the most of humans! It’s because of the consciousness level exist between humans ! It’s physical and mental together! The physical part is related to the normal circulation of the a liquid called CSF in the human spine, and it’s mental affect on the human mind and how brain is working! CSF is one Molecule away from sea water, one of its function is to wash the brain and regulate the brain activity! We are living in a time that most people are dealing with some type of muscle or body spasms, and this unbalance the spine, and if this unbalance become so high, the normal circulation of the CSF will decrease, until it could get completely blocked! If this happens somehow human consciousness get disconnected from its source, and start living as a mind story, or locally! This could make lots of mental and physical issues for some people+Repetitive thoughts, or self talking all the time! Bringing back the normal balance of the spine will circulate the CSF normally and thing get changed! For some people this release could be a nerve on their hand, some other body area! Human nervous system is like a tree, and this Stuckness could be at any body part!
This complete My Big Toe

Hoffman theories ( consciousness is fundamental)!CSF is the medium for Consciousness to enter the human body and if the normal circulation of CSF get blocked, the brain start working locally and consciousness experience the life as a mind story or a separate I !
These breakthrough videos are something I didn't know I needed, will definitely be tuning in next year
That's soo cool! I can have updates on the findings of the year summed up this nicely? We may have many problems, but living in this time is still really really fantastic!
I usually hold pop-sci in disdain, but this series is an exception. Actually communicating the discoveries in a way that is suited to those who are scientifically literate but not experts in the field, and not exaggerating/mystifying things for the sake of click-bait.
love you Quanta people! favorite mag of the year, thank you for keeping us effortlessly up to date!
Aaaaand I just switched my notification bell to "all". The latest information about the evolution of sleep is just fascinating. Keep these coming.
As a major stroke survivor, I find this fascinating.
I love these videos sooo much, I am waiting for this one since last year
Always a good time in the year when these come out
There's just so much knowledge waiting to be observed. It's amazing.
I always enjoy leaning about how little we know about the brain.
Very interesting, thanks a lot.
I would enjoy a deeper dive into the subjects and discoveries
You can read extensively reported articles about each of the discoveries featured in this video here: www.quantamagazine.org/the-year-in-biology-20211221/
Great video series! Good job, very interesting. Thanks
I recently heard that studies on lab rats showed that if you keep them awake long enough, until they die from a lack of sleep, it's problems with their intestines that cause them to die.
This has been confirmed in flies and may also be true in rats. Quanta covered these experiments last year: www.quantamagazine.org/why-sleep-deprivation-kills-20200604/
So if you take liver medicine can you survive not sleeping ??
@@koohletit1453 Maybe sleep was created and exists because of the body, but the brain still evolved for millions of years in creatures that slept, so things are probably going to go wrong in the brain if you don't sleep. It's not prepared for that.
@@DF-ss5ep The brain "evolved" just as much as eyes did, which is it never. Just like the video stated sleep "evolved" mistakenly. It's complete conjecture and not based on observable science. We see in the fossil record most major biological traits appear in a geological instant. No evolution. Virtually every structure/type of eye appeared in a geological instant with the Cambrian explosion, as did many other structures such as mouths, anus, almost all skeletal structures aloud by physics and so on. Darwinian evolution is not as strong of a theory as people assume it is just because of it's ubiquitous mention in academia. Then they make statements like "when sleep evolved." That isn't true. Science has not established such a thing. People do this all the time. Not trying to single you out, everyone does this.
@@WaterspoutsOfTheDeep you’re full of BS the moment you said that the evolution of the brain (and eyes) aren’t real. there has been NUMEROUS amounts of peer-reviewed articles that proves your argument otherwise. please do not get yourself involved in ANY scientific field ever again. you’re a conspiracy theorist, not a scientist or science enthusiast. you’re probably the type to believe in creationism, which once again, is also BS. to know that the human brain is so complex and then people like you exist? you are the best example that can be used in the argument against “the human brain is complex and intelligent” statement because clearly, it is the complete opposite for you.
Roger Penrose wrote about some of these ideas (placement of brain functions) in The Emperor's New Mind... in 1989. Worth a read!
I really don't get why some people don't like science - seeing an endless stream of amazing discoveries about our universe by humanity just makes me speechless😍
We are so lucky to be born in an age of such scientific and technological advance!
There should be more of these video updates on neuroscience research especially related to depression and epigenetics.
Just came across this channel and really liking it
This is Excellent!!! Thank you for the beautiful video🙌🌟
🙏🙏 thank you guys so much.. just love learning 🙏🙏
Incredible information. Thanks for making biology more interesting for me!
Thank you for the information. It helps someone like me who's learning the fundamentals of neuroscience. We need to rethink what we know about the subject.
This was fascinating. However, I think the section on neuroscience was a bit too one sided. There are different perspectives in the field, and to say that neuroscience is dissolving the traditional boundaries of psychology or that we can’t map any psychological functions to any specific areas of the brain is to ignore a lot of important insights in the history of neuroscience. From the way they speak in this video, you might walk away thinking that there are no functionally distinct anatomical brain areas. But that is false. The hippocampus really is the brain’s main memory maker. The motor cortex really does plan and execute movements. The basal ganglia really does store habitual movements. The dopaminergic system really does allow for anticipation and reward. The brain is not a homogenous goo.
Obviously but mainly what is it. still is the fact. philosophical psychology is the norm in which u approach variable’s in possibilities
Just because there are functionally distinct anatomical areas it doesn't mean that those functions correspond with the psychological categories we use. Your reasoning is circular. You're missing the point. The problem is not only empirical but conceptual. Many other organs are functionally organized, but those functions are strictly physiological (think about a kidney or a liver and their relationship with nutrition and excretion). However, psychological categories arise from the way we talk about behavior -c'est à dire, those concepts are adscribed to the whole animal. When we adscribe them to brain processes we might be mistaking the specific computational features that the different functional brain modules have and how they relate to psychological categories. That's the conceptual dimension of the problem: how to articulate a language used to describe the psychological with a language used to describe the physiological and the computational. And establishing a correlation among a lesion and a psychological (dis)ability, such as anterograde amnesia, doesn't necessarily entail that hippocampus is the seat of memory. It certainly is related with what we call memory, but we'd need to explain how in particular the physical organ implements informational processes associated with psychological phenomena.
@@GiRAaLLLdo I see your point, but I think you are arguing something more subtle than what I was reacting to in the video. I agree that many brain processes don’t translate easily to psychological processes and we sometimes force them to, which obscures our understanding of how the brain works.
However, I think the language used in psychology is often easily translated to that of brain processes. There are detailed studies of how, for example, the hippocampus forms memories of particular experiences (using the CA1-CA3 circuit), as well as how it instantiates our memories of physical spaces (using grid and place cells). In the case of memories of experiences and the CA1-CA3 circuit, this process seems to translate to what psychologists call “memory encoding” of declarative memories.
Maybe I’m not quite understanding your point, so please correct me if I’m off track.
Here’s the thing- psychology isn’t a science. A huge problem is when un-reproducible psychological theories come up against neuroscience’s discoveries.
Sure, humanities like psychology, sociology, and anthropology can help when the scientific method isn’t there- but they should step out of the way when science is happening.
@@jacob9673 I agree that there is a lot of armchair philosophizing that is touted as psychology. But I think it's incorrect to say that modern psychology is not science, because at this point in history most psychological research fully embraces the scientific method. If you doubt that, look into any major psychological journal and you'll see what I mean. Also, what separates psychology, neuroscience, microeconomics, and genetics are not bright lines, but fuzzy boundaries.
The newer sleep hypothesis makes so much more sense than "Sleep is of the brain, by the brain for the brain" in terms of health recovery and growth hormones production while someone is asleep.
"culturally-laden categories" is such a good way to describe it. the idea that specific parts of the brain correspond 1:1 with specific actions/states of the brain is… kind of wild imo. feels too much like the old "flesh computer" thing
also hi rafflesia!
The issue i'm facing with in vivo imaging of the mouse brain is that experience changes neurological activity and and neurological activity influences behavior which influences experience. For instance, we use isoflorine as a anesthetic and mice that have been put to sleep more show different activity than mice that have not been put to sleep often. It is very difficult to avoid confounds with voltage sensors.
That was awesome! Great job!
Wish this was longer !
Very interesting, informative and worthwhile video.
You guys deserve more than what you actually get on UA-cam this makes me feel sad for you🙁 i am always with you ❤️🤲

Phenomenal series!
absolutely stunning discoveries.
I remember reading somewhere that memories and skills are tied (or connected) in the brain, so remembering how to cut a paper access all the brain abilities differently
5:54 idk why but this is a way more helpful visual for me to understanding wtf genes are.
It feels fascinating when computational technology is helping us in discovering the wonders of biology. 😍
Great video! Very interesting information!
I love how the neuroscientist at 6:50 gives his interview with a 24-can pack of beer on his desk :D
His Secret Santa present maybe?
I recently read _Forgetting: The Benefits of Not Remembering_ by Dr. Scott Small, neurobiologist at Columbia U. In it, he discusses the areas of the brain which perform memory: the hypothalamus being the memory director of other specific parts of the brain. He also quotes the famous Francis Crick’s 1983 aphorism, “We dream in order to forget.” Crick was right. That is the purpose of sleep: to reduce the memory storage areas of the dendritic spines.
This video seems to present the old attitude toward sleep: that it serves no specific function.
Sleep also is when the waste in the fluid surround the brain can drain out too I believe. Maybe it's better/easier to just think of sleep as the opposite side of the circadian rhythm cycle. In that maybe we are limiting ourselves by thinking of it in a narrower box. Maybe there is much more we've yet to discover of what happens during sleep that we might be missing or miss-categorizing.

There are many hypotheses on the function of sleep, that doesn't mean any have been replicated enough to be considered to be confirmed or unquestionable. There may be more than one function of sleep, as there is some evidence for other functions than memory consolidation as well.

That was SUPER interesting. I have no idea if I'll ever get any help, but, I haven't been able to sleep well since my childhood, and I think it's all finally catching up to me. 😓 It really, really, really hurts.
I may have used up TOO much energy (with too little overall sleep) for too long.
Have you read Matt walkers book? Have you tried supplementing zinc magnesium & cbd?
@@sjofas Thanks for the response. So... No, yes, and definitely yes.
Unfortunately, not only is CBD bloody expensive (I think we all know that)--and I try using the pure tinctures (btw I'm in Cali, it's legal)--but it ONLY reduces my physical pain. Diminishing effects now, too... after about 3-4 years of (limited) usage.
I'd actually LOVE to try something 'crazy' like taking *tons* of CBD every day for 1-3 weeks. This would be to gauge any sort of demonstrable results (then, compare and contrast to 1-3 weeks OFF of CBD). But, simply enough, that would be way, way, waaaaay out of my budget.
Melatonin has also been yielding severely diminishing returns. :/ I'm all sorts of 'in a bad way', and there aren't really any valid, viable options for me.
My thesis on why we sleep starts with the circadian cycle and how light affects cells to be more or less active depending on the environmental information stimulating those* cells.
The most complex thing in the universe isn't as simple as we thought, who would've guessed
You get it lmao
Love this channel
What a time to be alive!
Keep Them Coming
This was so cool! I’ve come across many amazing channels that make videos on Physics & Maths but I’m more interested in Biology & Chemistry but I haven’t found anything. Can anyone recommend me good channels for these subjects?
i like how the more i learn about the brain, the more i think i understand the effect of psychedelics.
especially ego death experiences and all that spiritual talk about how we're all one etc.
it's probably just that the conciousness shifts to the inside and when halucinating you basically see a simulation of what's currently happening in your brain. hence maybe more repeated patterns and less of a whole picture for humans who can't have a long train of thought for a long time and more intense psychedelical ''trips'' for those who can.
of course then; different psychedelics have different effects on every different individual, yet i think this might be a very basic general explanation for the weirdness of psychedelics.
it'ld be really crazy what kind of new possibilities with mental treatment psychedelics then could bring.
nice video! thanks for the cut
So good!
It’s hard to tell how innovative the findings are for the neuroscience bit of the video. I mean, are there any neuroscientists saying that the mapped regions of the brain work in isolation? Are the findings that emerged from the case of Phineas Gage invalidated by this supposed “breakthrough”?
I was insecure that I blink too much when I try to explain the brain to my friends, but I'm glad and relieved that people who've studied the brain for decades, let alone years, blink so much as well.
The circular animation of brain functions proposes a circular movement from the outside to the inside. The converse seems more plausible to me - motion going from the (or, 'a') center to the periphery. Cf. studies that show that basic consciousness 'starts' or emerges from the brain stem.
That last one is mindblowing! I need to go to bed now.
Other, not-so-recent, yet fantastic new areas of the human body to rediscover are: interoception, the connective tissue (fascia) as our primary sensory organ, and the gut microbiome. Each of which give you a proper understanding as to how important physical motion/expression is for our survival, how we can better protect ourselves against ‘pain’ and improve our immune systems.
Incredible!
This is cool but it would have been cool to get these three topics in different videos. But it nice to know in short
Amazing video :)
I have ALWAYS disbelieved the "mappings", but felt that there were "circulations" of borrowing associative patterns. For example, think of a rose, visual cortex, emotional cortex, logical cortex, color cortex, etc are used to "understand" a rose...and there are circulations. Neural networking technology confirmed this for me. We use tuning/learning with neuroplasticity AND variations of effects of axons on dendrites (inhibit/promote) sums of inputs.
Great video
This is so cool beyond fascinating
Good stuff!!

Facinating!
This is key to unlocking more human brain capabilities. Once we tell our brain its there, it eventually will work it out. Like riding a bike. Education will be specialised specifically according to the vibes of your brain. We can know at birth that a child will be a good doctor through one brain scan. We won't waste time teaching a person things unnecessary to their purpose hence faster development.
Memory needs to note specific conditions within a set time, unknown to us, and to do that it has to memorize a specific sequence that the brain has at that time.
For example, you want to remember your first date with a significant other. The brain needs to remember the event, your knowledge of the event, who the SO was, your relationship with them (your feelings about them) your perception of what was happening at the event, your memories that influenced you at the time. Your body needs to remember specific muscle movements such as a first kiss, or walking in the park, or sexual activity and relate certain emotions to that.
All of these utilize every aspect of our brain and recreates an event. For most people this process is hard to do, hence poor memory, but for some people they can remember everything about an event. It's super fascinating how intense recalling memories. If you're bored one day and feel like really trying to remember an event, sit down and put all your focus into that memory. You will remember more of it, but you will get a bit of a headache since your brain is thoroughly trying to figure out everything and give a close to accurate representation of it!
Don't forget to mention the basal ganglia. These are an up-and-coming area of great intrigue and interest. Also, how does the brain integrate information? The binding problem of consciousness.
This is really cool.
One of the best tip for anyone to boost their productivity is to get enough sleep. No matter which strategies or methodologies you employ, if you don't get enough sleep, you can't be productive. Happy new year to all!
What I understand about this video is that sleep used to work exactly as in video games where you sleep to regenerate hp
Truly amazing that the video game industry discovered that before scientific
Another idea is that it is visual areas telling the rest of the brain that it still needs that brain space. As neurons/areas which are not being utilised tend to get "taken over" by active areas, by generating visual stimuli in the form of dreams, the occipital areas stop other areas stealing its office space!
facinating!
good one !
Amazing
Acquired savant syndrome... This happen to me... I love these video's... BIL
Wow. I didn't even know that before this discovery it is 'known' (or hypothesotzed) that small animals such as cockroaches don't sleep.
Anyway, i have some questions:
1. So brains are not just nerve nets - or neural networks?
2. What's the difference between sleeping and awake hydra?
This actually makes sense
I think the original theory of independent brain parts implys that the sections of brain act as if they were a human in a company, whereas the study implys that the brain uses different parts of the brain to form various forms of circuits. though different sections of the brain consist of different properties, it doesn't mean that they are independent-humanlike features, neither are they a concoction of different functions - which is easy to imagine when the phrase 'independent mapping of brain sections is false'.
Breakthrough in neuroscience: Neuroscience doesn't know wtf it has been doing at all
Can you suggest any individual, institution, or entity which may have contributed more to our understanding of human cognition?
We are programmed meat robots inside a Matrix , If you look at the function of all the organs of the body, including the brain, you will find that all the organs of the body have an automatic function, including heart rate, gastrointestinal tract and blood flow, and brain function! Now, if we assume that there is free will and that we are the product of this process, we must be able to explain how, as consciousness, 100 billion neurons interact with each other to produce a thought, in fact no human knows what is going on inside their brain When a thought is produced, the only thing we understand from the thought and what is produced inside our brain is the image and sound that the brain produces, the brain automatically adds our thoughts to our vision! Thinking is like a transparent curtain that adds an extra layer of information to our vision, we see our thoughts but they do not exist in front of us! It is the human ability to see things that do not exist outside of the human body in the Matrix ! The body-mind problem (Illusion of freewill) occurs in the humans when the nervous system get contracted, when this happens the thought process automatically begins to think! And since most people have more or less nervous system contractions, they have this extra thought in mind. ! And in the long run, these thoughts almost become an additional operating system, and it decides for itself and gets the person in trouble! This extra operating system is the same 'I' that everyone has but does not have an external existence. If the nervous system calms down, this extra thought process automatically stops when this 'I' or visual curtain is removed, awareness and Understanding is not of the body, consciousness in the human form it sees itself as somebody and it is separate from the function of the body! The human body is essentially part of nature or simulation, and we experience the world as consciousness through a mediator who is our body! In this simulation, everything is pre-planned, because all human beings are part of the simulation, and in fact, in this simulation, there is really no one, except a consciousness and a running simulation!
All thoughts are extra thoughts, because life is a predetermined simulation! People get lost is their own story and this makes different level of consciousness in the societies, and somehow people at some level get stuck or programmed and they live with it, that’s why a small group of people are controlling the most of humans! It’s because of the consciousness level exist between humans ! It’s physical and mental together! The physical part is related to the normal circulation of the a liquid called CSF in the human spine, and it’s mental affect on the human mind and how brain is working! CSF is one Molecule away from sea water, one of its function is to wash the brain and regulate the brain activity! We are living in a time that most people are dealing with some type of muscle or body spasms, and this unbalance the spine, and if this unbalance become so high, the normal circulation of the CSF will decrease, until it could get completely blocked! If this happens somehow human consciousness get disconnected from its source, and start living as a mind story, or locally! This could make lots of mental and physical issues for some people+Repetitive thoughts, or self talking all the time! Bringing back the normal balance of the spine will circulate the CSF normally and thing get changed! For some people this release could be a nerve on their hand, some other body area! Human nervous system is like a tree, and this Stuckness could be at any body part!
This complete My Big Toe
Theory by Thomas Campbell, and Donald D. Hoffman theories ( consciousness is fundamental)!CSF is the medium for Consciousness to enter the human body and if the normal circulation of CSF get blocked, the brain start working locally and consciousness experience the life as a mind story or a separate I !
D'OH!
First one is not new at all (and their answer is not as accepted as they suggest). Definitely not a “breakthrough”, but still interesting to consider the extent to which the brain (and the mind) is specialized. This debate existed even before we started using fMRI to understand the mind and the brain.
I'm not a scientist but I definitely do believe one of the reasons why we still dont understand how much of the universe works is that we study things in silos instead of recognizing that on some level everything is interconnected. Studying things in silos prevents us from being able to see the bigger picture and having a complete understanding of everything, the human body included
As a scientist, i can say that science is as fluke as the mind. We can't separate things apart and investigate. Even the very looking changes the things, there is no way of understanding anything with the conceptual mind.
Lisa Feldman Barret is an awesome neuropsychologist, check out her book "How Emotions are Made", mind-blowing stuff!
1:00 That woman is just brilliant. I saw her on the Lex Friedmann Broadcast.
Life is diverse;
And nature surprises us interbeing humans
