love when scientists admit they aren't sure. makes me trust them more for some reason
Even the best explanations are understood to be provisional. That’s the beautiful part of science, it’s collective modesty. I agree completely!
I like it better when they know stuff, like this guy did.
Yeah, honesty...what a concept.
@@ROForeverMan which he would know, since he has a doctorate and you flunked out of grade school.
@@ROForeverMan Well, the brain seems a pretty good place to start on a video titled: " How brain scientists think about consciousness ". If you feel that you have a better theory about the nature of consciousness you probably are not going to be satisfied with any empirical, scientific attempt to explain it. Just go with you're gut.
"We haven't the foggiest"...That there ladies and gents is a true scientist
Having recently binge watched a ton of videos on physics, quantum mechanics, philosophy, and consciousness I really get the feeling that we know next to nothing on virtually everything! And that almost everything is composed of basically nothing. Really very very frightening to be honest. I think I just want to believe in santa and the baby jesus again...
@@aquacruisedb what have you been watching??? Consciousness isn't mysterious. It's a tool used by a god like observer to ensure its characters within the movie of spacetime "feel" their experience. If you read this and doubt this, than you simply deny, or fail to comprehend special relativity's block time experimental assertion.
True. I wish I had a job where I could say I don't have the foggiest and still get paid well ! 😊
@@jack.d7873 Well played, I almost took you seriously 😂
@@aquacruisedb Don’t let your insecurity confuse you into thinking everything is devoid of meaning. It’s easy to get lost in existential questions, but the important thing is to slowly take in the information and accumulate experience to deduct and piece together the truth. Wanting to believe in something without thinking is running away from reality, not taking the responsibility of your own life seriously.
Such an amazing man. He passed in 2017. I'd love to know when this interview took place. He was a pioneer in his field.
i'd say mid 2000's based on the monitors in the back
I'm pretty sure this interview occurred in late 2018 /s.

@@stuartmackinnon3063 Lol. The interview took place in 2018 but he[the scientist] died in 2017. Wow, he must he must have used some part of the brain to time travel. Amazing what they can do these days.
@@elephantrambo No later than that. Probably just a few years before he died.
He was my mentor! The man I looked up as a student and continue to admire and think of to this day! Arne, we love and remember you, thank you!
I could listen to him all day. So many questions.
Wish I could have had a conversation with him. Seems like a kind genius.
"We know certain things and there's so much that we don't know" Dr. Schiebel
Consciousness is still the greatest mystery💫
There just simply isn't an abc answer to explanate certain things. We don't even know what came first, the chicken or the egg
in the end times we will know all things - God
I love that Dr. Scheibel has no axe to grind. He summarizes the science so far and expresses wonder at what is still to be learned.
thank you for "no axe to grind". I didnt know that.

@@ROForeverMan you're right! He should have mentioned the angels that live within the cerebral cortex.
One thing this guy said was facinating in regards to stimulus of the brain not being regarded as a threat. At my work we have a vent fan that constantly clicks. Its not quiet, its fairly loud. I listen to it all day every day and i only hear it when my attention is brought to it.
If i am just working away. Its essentially no longer happening. I do not hear it.
Your intent / spirit. You're a collection of frequencies that have understanding. The " charge " intent gives direction. It works in tandem with the parts of your body. The brain is a console.
I Love how matter of fact he puts it,
we haven't the foggiest idea and keeps up the cadence of the topic,
Love it. Thank you so very much for Posting these beauties, fascinating conversations, topics. 🎸💚
This is incredibly satisfying to learn. I’m literally a deviation of what’s in his hand, learning about how I work on an biological level, as well as understanding the fringes of how that ties into emotional experiences.
it’so fascinating to see how enthusiastic and passionate a brain can be telling about the brain
One of the best speakers in this series.
...just brilliant! RLK continues to ask those fundamental questions about our collective 'brain'. So fascinating to hear a specialist describe parts of the brains separate functions in detail ..
He stopped asking questions april 2017.
This is beyond interesting!
I would love to listen to His entire lecture.
I came to this channel to broaden my horizons in the field of Physics, Cosmos, and I became interested in the brain and consciousness!
Thank You so much, Mr Kuhn and CTT Crew!
Check out near death experiences. Best testimonies of the survival of consciousness.
Brooooo, I have never heard such concise and simple explanation of what a brain is.
@@ROForeverMan well not sure if I can stand by your explanation 🤔 the brain is definitely there, we just need to learn more about how it works.
What a wonderful explanation of consciousness in that last 30 seconds.
What a great interview and exchange of ideas and information. Thanks. 🤔
This is SO fascinating, it demands many many listening!!
I like the way this Dr. Explains things!
What a wonderful chap!
Always great content, helps me get a grip on new ways to view existence. I discuss this content with the community and always goes down well.
@@ROForeverMan physical effects tend to have physical causes... there's a causal link between the brain and consciousness. Don't you think their viewing of consciousness, which directly mirrors states of the brain/body, is a key indicator of something material/physical underlying it?
@@ROForeverMan if I slap you with a tree, will it hurt? If I poke your brain in various places, wouldn't you react in various ways? You seem so sure to know what 'consciousness' is. How do you know it isn't an illusion produced by the brain? You are your body, you do what your body does, and your body does what we call 'being human.' You feel yourself to be this little central point within yourself, from which all seems to be flavored to produce your feelings of 'you.' How can you be so sure your understanding of the way it is isn't just that, your particular understanding? I'm assuming you look forward to an after-life as well?
Thanks a lot for this clear explanation, so precious!🙏
Love the work!
I love the way he frames the first question
Spectacular!
Amazing, thanks.👍
Love it how he says ‘we don’t know’ and is completely at ease with this answer.
The best explanation I've ever heard is that the brain is a Transducer. Here's the meaning of that.
According to the Neural Transduction Theory, the brain is a transducer, which means it is a device or an organ that converts one signal to another signal, commonly from one medium to another.
The theory suggests that the brain acts as a transducer between our existence in this world and our consciousness, which can access a different realm.
The brain is encased in transducers that convert distinctive properties of electromagnetic radiation, air pressure waves, airborne chemicals, liquid-borne chemicals, textures, pressure, and temperature into similarly distinctive patterns of electrical and chemical activity in the brain.
The theory of transduction suggests that the brain is not a self-contained information processor, but rather a device that sends and receives signals from an alternate universe.
The theory of transduction is directly testable, and empirical support for this theory has the potential to profoundly change our understanding of ourselves and our universe.
Also I like this: That we are projecting our consciousness through a much higher dimension all the way down into our brains.
I also believe that everything is floating in Consciousness and that the Creator or the Supreme Intelligence is experiencing itself through it's Creation.
The Native American Indians call it, the Great Spirit or the Grandfather Spirit.
we r all mad as we think that the delirium our brain produce is a form of reality .. our body receive signals from the material world signals that r capped by our sensors nose eyes skin and these signals gave an image of the world animals plants insects probably see the world differently
but our brain produce also reasoning illusions visions of reality
has a abstract creativness so we invented religion philosophy magic science and introspection
the machinery that studies itself
this introspection leads us to a such sophisticated vision that become madness .. in each period of time. we have mad monks philosophers or messianics mads and they have a lot of followers
today internet is producing another phenomena too early to see where it leads
It helps me 5o understand chronic pain I live with. Thank you

Wow, this guy bears an amazing resemblance to the late great Vincent Price, who portrayed scientists more than once in horror films. When I saw him with a brain in his hand, I couldn't help but be amused and amazed. That being said, I have great respect for these two distinguished gentlemen.
very clear explanation of some of the most important bits and pieces of the human brain...
true indeed..but there is still no explanation of how consciousness emerges from that squishy wet fleshy organ...I doubt we will ever come to the point where a scientist makes a video explaining that..I personally think it will forever remain a 'mystery....
@@Dion_Mustard you have to make a distinction as to what level of conscious activity you're trying to understand... if you want to understand how a human brain becomes aware then you have plenty of clues from this video alone... I think, consciousness is a property of living organisms, and yes I understand, this might not appeal to everyone but for me it's hard to equate consciousness with inert objects... who knows though, I also accept my limited ability to understand it and that has to do more with the realm of unconscious activities including dreams...
@iarguephilosophy you can say that, agreed... the title comes as a hint here, though (Robert, as usual, is very careful as to not step on more than a territory at one time)
@@r2c3 even some of the greatest thinkers (Chalmers/Fenwick/Hammeroff) do not accept consciousness is a product of brain, so I remain open minded.
@@Dion_Mustard I tried to be careful as to not being misunderstood, but maybe I was not clear enough with my previous comment... I perfectly align with your stance of open mindness and I'm also trying to push one step further, by finding a way to analyze our understanding... any thoughts on the topic are welcomed, my moto is two minds are better than one (there's exceptions, yes :)
This is so great!
Its mind blowing how we have mapped the brain to every function of the body, but still no sign as to where consciousness fits in.
We are all looking for where for a better word the signal comes from. We all have to keep trying to join the dots to see what we get.
When the brain is mind-blown by the fact that it can realize that it is mind-blown 🤯 On another note, I think we cannot find where the consciousness lies because we are too focused on finding the "core" or a specific part of the brain that can contain it. What if the consciousness is the sum of all the parts of the brain? What if it is determined at the quantum level? What if it is not a physical phenomenon that can be observed by our current knowledge and means? I feel like these scientists need a paradigm change sometimes.
@@ROForeverMan hahaha, now that is mind-blowing.
Consciousness is the brain simulating itself in order to plan for the future. It's not surprising you "imagine yourself" when you are (say) planning what would be the best route to go to the store, the bank, and pick up your kids from school. It's hard to localize in the brain because it's the full symbolic network of thoughts evolving over long durations that cause consciousness.
@@darrennew8211 thank you for jumping into this little debate. In that sense, all animals are conscious. But the brains' only function is to maintain the body, that's it. It still a fascinating topic because there's no definitive answer as to their binding. There's an awesome book called "you are not your brain" that everyone should, at some point in their life, read. You all are awesome, even the funny, jokery comments. I believe that mere fact that you enjoyed this video says a ton about you.
Full video plz
i love this!
Is having too much emotion a bad thing? There's a lot of questions I have.
This is just a great video, wow.
yes. having too much of anything is bad. that's what the words "too much" mean
If the “too much” is hurting yourself or someone else than I would say yes. If you’re a comic and your intense emotions (think robin williams) is making everyone laugh then I would say no. But if that comic goes home and can’t turn it off and starts drinking and drugging then it would be bad. So it depends I guess.
great talk. thank you

Excellent. Excellent. Excellent
Good example of a professor transmitting information with his full capacities online.
Would be some crazy stuff if we managed to recreate the brain that enables advanced consciousness and set certain genes which presumably code for the development of the human brain (containing an advanced consciousness) yet its given to an animal to create its own advanced conscious mind or a more intellectual version of its former self.
Waking up every day and not remembering yesterday isn't "groundhog day".
What a wonderful gentleman for a guest. But I didn’t hear too much about consciousness
It's how we think about consciousness, I.e. as processes of the brain
@@ROForeverMan absolute nonsense
@@ROForeverMan PET, f/sMRI, MEG, EEG, DWI, MRS.
I think it's the crosstalk between the systems of the brain. You have systems just for things like taking sensory input and constructing reality from it. It's a system that would be made worse if it had more to do than constructing the environment. After it's done with it's job, the construction is sent via neurons to the other areas of the brain by going thru the crosstalk area, where your consious awareness is. The 'you' you feel you are.
The point of the crosstalk would be to sort all the inputs from the construction of environment, to your memory, to muscle memory. Notice how when you do these things it's almost like you are possessed and just know how to do something. Crosstalk would take all these seperate inputs and use its higher order awareness to make decisions, decide what is worth focusing on. How often do you get an urge to do something from one part of your brain, then decide not to act on the urge because say you want to lose weight and that's more important. The urge comes for subconscious, and is cut down by your higher order conscious decision making.
Cortex gets two incoming streams:
1. Specific. Primary- what, where?
2. Non-specific. ARAS- intensity- how much, how frequently?
“These two have to work together.”
“The reticular system monitors our attention.”
“One of the basic foundations of what we call the conscious experience - consciousness - lies in this reticular core of the brainstem, and its modulation of…cortical activity.”
Here’s how I would interpret:
1. Paint (‘Modal’) - what and where. But the where - this is critical - is what 3D vector orientation outwards from a point self at pupil. Sort of 2D. And the what is just associative (‘skewer’).
2. Frames/Rings (‘Amodal’) - the sampling rate, sensitivity, and location(s) from the incoming video once interpreted as 3D.
I have beef with one statement- this constant assumption that memories are laid down in HPC first then shuffled over to cortex. I think memories are laid down in cortex, and it is the complex categorization handle (which enables retriggering at apropo times) that is first stored in HPC then shuffled or taught to cortex. HPC is too tiny to store so much stuff IMO.
Love it
It gives some explanation on emotional instability and why it occurs to some degree. I feel in the movie the matrix- by installing programs hits on the hippocampus and sends a program to the dna. Trying to use metaphors to understand. FYI there is a doc on t=youtube with the man with 3 second memory. It was amazing and sad. Thank you for this .
Any of you remember the very first moment when you became self aware, more or less your consciousness coming alive? I do (at least I believe I do). Now in my 50s my memory of that moment has never changed.. just seems odd.
I recall when I was about 4 years old that I could remember what happened the day before! And I can still recall that moment!
i think around 8th grade is when i really started to control my actions and being more "aware" of my concious decisions. not sure though.
When I was 4 years old, at my grandmothers, on a small bike on her 2nd story deck, I then immediately made the choice to ride off of it onto the stairs.
@@Username34823 8th grade sounds a bit high, I think that more happens in like 4-6th grade
@@hallo7053 it’s a high age I agree, but I think it’s the age where I really identified that I exist, in terms of life, God, purpose, etc…
A big question for me remains.. Is the brain a receiver of reality, or a transmitter? In other words, does it come from within our bodies, is our brain creating the 3D space 'illusion'. Is this what the brain is building up from the scattered atoms/light. Or are we truly roaming spacetime and receiving external consciousness from an outside source, is it built from our experiences, feelings and external stimuli. Is it really there, is this true 3D space? Consciousness for me is either connected to the source, being universal love or a product of evolution being a logical step in the evolution of the universe trying to understand itself. Hence we are the observers observing itself..
I would recommend you to watch some videos on ephiphenomalism. Because traditional evolution does not need/ gets no survival advantages from developing qualia to accompany action. But you defined evolution a little bit different as having an aim.
Thank you for this important discussion. Even with our current scientific understanding, we can conclude that all of this activity happens for "existence". The body as a collection of groups of cells is just trying to exist. Each cell is trying to exist. Actually that trying it self is the existence. What we arbitrarily call consciousness is the whole process together. But it is all just one big chemical process. That's it. And then we go to sub cellular, molecular, atomic, sub atomic, energy, nothing... are all levels of existence. And what drives this each and every process is the "bonding". Existence itself is bonding. On a macro level we call it wanting, lust, greed etc. So there is no separate entity as "conscious I". I would be grateful to hear any scientific response to this explanation. Thank you and I apologise for any limitations in language.
So you'd say our 'experience of being' is a function of our being itself? Do other animals have an 'experience of being' or do they remain in a kind of sleep, incapable of meta-thought?
No matter what 'I' do, 'my' body will function the way it was intended to, would this mean I not something separate from the body? What produces this feeling of separateness?
@@ROForeverMan if everything is conscious, nothing is conscious.
I am not a scientist, but ask a lot of questions. Mankind is capable of thinking, making choices and conclusions. There is constant movement to do this. Studying the metaphysics, one learns everything is energy and force. So, what moves this energy and force? What is this energy to begin with? To be able to move your consciousness away from you body and be creative and interact with others, tells us there is something more than just a body housing a brain.
Cf. Spinoza
@slumpkiid3570 I would say thought creates this feeling of separateness. We try to think about ourself but find we can't capture the living experience of ourself functioning by thinking the thoughts that describe that. I.e. the word sad dies not capture or contain the live sense of being sad. So thinking about or describing sadness or any sensation of living separates from the live experience. I think we cannot actually thi k about ourself and know ourself that way. Because what we think changez what we think about...and so the result is something other than knowing ourselves as we were before change by our thoughts about ourself. I have found knowing g myself as I am only exists as the live sensation and thi king about myself and capturing that sensed knowing is not possible. Conclusion...thinking only works for the purely mechanical navigation of life and cannot be used for knowing ourselves or the living. That seems to be only the domain of the living organism when feeli g it's own existence.....what. do you think.....
I think saying we haven't the foggiest idea is a bit too strong. We have quite a bit of hard information on how it all works, but there are parts that still elude us. We also have quite a few solid avenues of research.
We may not be able to answer how an experience forms, but we can retrieve bits of it already. We also now understand( it should be soon accepted in the wider community) that our self is quite probably not housed in the brain only, but in the entire body. The theory of consciousness as an emergent property is quite solid.
Well done, nice encapsulation.
Do you mean consciousness as a weakly emerging property like in water? We in reality can model the behavior of water to a pretty high degree in computers. With mind qualia we don‘t even have a clue how we should write the first line of code to do that. If consciousness is a strongly emergent property this puts it outside of the list of things that can be even in theory be investigated by science. Emergence is in reality no „theory“ either, it‘s a philosophical concept under which different phenomena’s are summarized which are hard to model/predict from the parts.
@@Rakscha-Sun
Look. I don't follow the emergence theory/idea that closely. It just sounded like a no brainer explanation when it comes to these phenomena.
I mean it wouldn't be the first time, that someone comes up with a mathematical expression for a philosophical concept, right?
And I think we're coming closer every day to making that leap. It's just a matter of changing one's perspective enough.
And what do you call those experiments where we're reconstructing back sensory information from brain activity? I understand that qualia are still something else than just decoding sensory, but why should it be in a different vein of research? E.g. we've got some ideas and we're trying to confirm them / find the correct mode of thinking about them to gain any practical insight. But It's not that we're completely in the dark like 20 - 30 years ago.
Amazing video....This channel has been filled with idealists/sollipcists.

@@Joepoe-ri6vt who do u want to have a chat with? Everybody is just an idea in ur Consciousness isn't it??
@@Raj0520 hahaha we can explore that if you’d like. I wouldn’t necessarily call myself a solipsist however i do think that solipsism has been misunderstood since Descartes. Again, if this isn’t something you’re interested in talking about you can just say.
The issue isn't the brain it's our connection to the information in the brain. As in a computer, it's not the processor, memory, or stored of data, but it's the person viewing the monitor. Where is that person in the brain/nervous system.
@@NoisySplatter and that process is to observe what is happening and draw conclusions. Your stupidity is boring me!
The problem runs even deeper. Computer just follow rules. If consciousness is a computation this rules must lie outside of the brain (unlike the computer, there is no architecture to start with that defines the rule to follow). If physicalism is true take the form of natural laws but there must be millions and millions of them. The complexity of the laws would be close to the complexity of a working mind. If such laws exist we can not say that evolution is a random accident nor that the universe started from simple laws.
@rakscha836 nice! Yes it physicalism is true, then it confirms the existence of a Supreme Being with intelligence beyond our current knowledge.
awesome
True science. Wow.
Thinking is the process of communication of physical signal impulses among sensory and motor neurons that produces logical DNA data.
Taste (consciousness) is the process of communication of chemical signals among organic and inorganic compounds that produces taste enzymes.

Once the brain dies, so does the consciousness. Having a conscious is too short yet sweet.
Yep....When the Tv breaks, the Programme Transmitter just keeps on churning out....Maybe...just maybe...You are something more to do with the Transmission process than You realise.... Conscious survives the Tv....!?
@@1SpudderR Maybe... maybe not. At least you can replace a TV. You can't replace a brain. No evidence that consciousness continues after brain death.
@@1SpudderR oooo! nailed it you did your homework 😄 👍
The brain is a vessel of consciousness. The Body does not function without the brain, ultimately, but consciousness lives without the brain.
@@seanchaney3086hat makes zero sense. If there’s no body there’s no you. If people who don’t exist have a conscious would that mean unborn potential people also have consciousness? Both the unborn and the dead are in the same state of non-existence and unborn people don’t have consciousness then neither do the dead.
Great job doc. Thanks. Normally we'd have to pay university fees for that insight.
Thanks 🙏❤️🇮🇳
It's ok to say we don't know, leaves room for more exploration
Genius
Wonderful explanation! Top scientists coming down to our level to make us understand! Thanks to RLK and ABS.
This is a human experience of consciousness. Consciousness is all lifeforms and even in single cell organisms. Consciousness is what separates us from regular elements and molecules
How the brain's function it works ?to work need have cells and every cell is like a bettrey and every bettery need to waste energy or absorve energy so how can we calculate energy?
First of all: very nice guest, very interesting conversation. However, what ive learned in university shines a different light on the roles of the cortex. Im not sure its correct to see it solely as a repository. Especially the frontal, cingulate and insular cortex seem to be more centrally involved in our experiences. That is even excluding the sensory processing all over the rest of the cortex. But i guess hes trying to simplify for understandings sake. I get that, but sometimes feel like that makes people underappraciate how complex the brain is and how little we actually understand about it.. Overall still a good view though :)
you need to research where the information is coming from that you have been taught. he told you and where did your professor get his information from?
which text books are used and who wrote those books...
@@OnlyThe1Son we always read different peer reviewed studies on each topic, to get a better picture of whats relatively clear and what is not. Thats something that a video wont properly capture. But beyond that i just think he is talking about a specific viewpoint on the role of the cortex that isnt necessarily popular (although of course i may have received skewed information, would love to hear from somebody better educated on the matter than me). But it should be clear that university isnt like school, where you have no idea where the information comes from and how to validate it. Plus, in neuroscience and psychology, the current state of research changes very rapidly. Its hard to keep up, and some researchers have built models and understandings of neural function that they have committed to so much over the years, that information which just wont fit in that framework may be disregarded or explained away (it is almost always possible to explain findings in different ways. That can cause other problems though, such as needless overcomplication, which tends to be less likely to be true, or removing possibilities for falsification). Im not at all saying hes a liar, just that different researchers deviate from the commonly agreed (and thus most cross-checked), up-to-date, and empirically supported view, because these researchers are also just people and are trying to make sense of this huge pile of data in their unique way, which is bound to include some leaps of faith and, possibly, fallacies.
Btw. In some of his statements he is also explicit about the fact that he doesnt know this to be true. For example he says that he and other researcher *believe* the reticular system to be the seat of consciousness (if im recalling that correctly)
Great explanation.
Unfortunately the only thing you'll ever learn about consciousness in a university is correlation, not causation, as science continues the idiotic dead end march that mind arises from proper arrangement of inanimate particles which is a logical absurdity from square one.
Consciousness is a process running in the brain. It takes input from external processes in order to track and predict what they will do. It generates outputs with the aim of being able to survive and replicate. This process becomes aware when it takes input summarising its own state, and tracks and predicts what itself will do - it recognises itself as a process. This includes measures of how well it is surviving and reproducing. Free will results from its outputs being available to it to inform future processing. 'Free' here means attributable to conscious decision-making, so that outcomes can drive learning that will improve future decision- making.
why is there a slight weird dementia sound at 5:20 end at around 5:45 to 5:40(its like a low frequency sound thing idk) nvm its placed through like the whole video but reduces at certain parts
How and why do our neurons respond to stimuli from the senses?
Does it process that information like co.puter processors (logic gates at the core), or is it something like this visual stimuli that activates this neuron curcuit that creates an action?
