Can there exist anything that has no energy? If not, then where/what is the energy that allows for the existence of our sensorium? Is it just spread out all over the brain as electrochemically stored energy? How is that energy so precisely pieced together for the observer that, for example, the visual field appears as a completely uniform entity?
Surely our consciousness is contained in the universe?

So, you want to know how transferred energy gets translated into perception?

Okay.

Sight:
Waves of Light with E = (hc) / λ (Energy = Planck's Constant times the speed of light divided by wave length) and further λ = h/p (p is the momentum) so E = pc. The light hits certain cells in your eyeball, transferring the momentum to the cell giving it some extra energy, the extra energy is sent as an electrical signal down nervous pathways to be decoded in the brain similar to how television signals work (though it is a bit more complicated, that is the basic picture of sight)

Sound: Similarly, Soundwaves have a specific energy E = pu where u is the specific velocity of the medium. The soundwaves travel through your ear canal until they hit certain bones in your head and transfer kinetic energy which is then decoded by your brain.

Touch: (Specifically hot/cold) Energy is transferred following thermodynamic rules from hot sources to cold sources through kinetic interactions between the molecules/atoms or by giving off photons at which point the sight analogy above applies, except it is being decoded purely as heat rather than wavelengths. The higher the temperature of an object the more energy have, and therefore when you touch them, the atoms of the object bounce harder off of the atoms in your skin. Pressure follows the same rules, except instead of the energy of the individual atoms, the sensation depends on the total density of atoms in the object (more generally, a fluid) Pressure is the feeling of your butt in a seat, and the seat pushing back against your butt, or the feeling of being underwater, the higher density of water (when compared to air) and the water compresses your body a tiny bit.

The question is more about the energy that is directly behind what we sense - when I observe an object and my brain processes a picture of it, where is the energy making up that picture? Surely the picture can't be merely zero-energy "information" because there is no physical medium existing for that in the universe.
Am I perceiving the very same energy that is burned from sugars I've eaten?

>> No.7181028

>>7181010

The picture in your imagination? That's your brain firing off the same braincells involved in vision, yes the energy they use is from sugars in our blood. "Perception" is a mental process, our sense organs simply supply information for our brains to construct our "perceptions". This si why you would have no way of knowing if you were a brain in a jar, being fed digital information in place of sense information. What "you" would "perceive" would be exactly teh same as what "you" "perceive" right now.

This is the part the questions are most related to. When the BRAIN is picturing vision, where/what is the energy that makes up the picture? When the brain is "filling in the blanks", it has to transfer energy in the precise way that results in us "seeing" something. Since that energy is seemingly scattered non-uniformly in the brain, how can it piece together a uniform image? How can our visual field exist one way when its energy exists another way? It's like an object existing in a different configuration than its atoms/molecules.

No instrument exactly reproduces the field it is detecting in the output. There are things like noise and error corrections. The same thing applies to the brain. It's more amazing that the output is so close to reality.

There are a lot of parallels between brains and computers. That's because they're pretty much the same thing. You would think by intuition that the brain doesn't "use" any energy, but the same applies to computers. An ideal computer doesn't use any energy, it's the fact that circuits have resistance that they use so much power. The brain, too, "uses energy" when thinking. It's not a 0 energy system.

Further in the chain, at the very moment when the brain has processed a given picture for itself to view, there'll be the picture in terms of the physical happenings in the brain and the picture that is observed. I'm asking how these can differ. How can we perceive something that has no DIRECT and exactly equivalent physical form existing? How can the observed picture exist?
An object can't exist in a form differing from the exact configuration of its particles, spacetime can't disobey its own exact curvature, etc. Why can our perception differ from its physical medium?

When you stick a pin in your arm, your brain uses chemical energy to "feel pain" as a reconstruction of the information your arm is sending it. The sensation of the pin in your arm IS this pattern of brain cells firing. Likewise, when you see something, your brain uses chemical energy to "form an image" as a reconstruction of the signals the eyes are sending it. The image in your head IS this pattern of braincells firing off. We experience it as a visual phenomena, but its the same exact chemical-powered brain activity that produces the sensation of pain, just in a different part of the brain.

Yes. In the same way that photography can be described as "just pixels." What they described can be applied to you seeing a delicious sandwich.

The feeling of longing or entitlement for that sandwich are just the same. It can all be caused and explained by chemicals and electricity. That does not detract from its deliciousness or make it any less significant in your mind.

>>7184669
>How can we perceive something that has no DIRECT and exactly equivalent physical form existing?
Because that's the only way that you can perceive at all. In the same way that a camera will take a picture that doesn't exactly match reality (It wasn't really that dark, that isn't actually blurry and fuzzy, it picked up some IR light that wasn't really in the visible spectrum, etc,) your brain has to do a lot of tricky shit to perceive anything in the first place.

The signals we receive from the outside world can be in numerous forms, such as photons hitting our eyes or sound waves hitting our ears, but the first thing that happens to this information is that it gets converted into electrochemical signals in the brain. It is these internal signals that you experience, modelled (hopefully) after the sense data hitting your senses from "outside" but ofc not necessarily corresponding to anything actually "real": The images you see when looking at a delicious sandwich are made of the same exact brain patterns you see when DREAMING about a delicious sandwich, and they are experienced by you in the same way, as a visual representation of a sandwich.

The question is NOT asking why our perception differs from what is being perceived. It is asking why our perception differs from what physically exists inside the brain as a representation of what we're perceiving.
For example, there is a crude and distorted mapping of our visual field in the occipital lobe. In a study a gorilla's occipital lobe was imaged when there was a target pattern in its field of vision. The target pattern was clearly identifiable in the image, albeit fairly scrambled. (Sadly I couldn't find the study at this time)
Since there's a scrambled version of our visual field inside the brain, how come our perceived vision is not scrambled? Our perception is necessarily the exact interaction going on in the brain, yet seems to differ from it.

>> No.7186738

Does it require "reconstruction" of the information contained in the pattern for the brain to be able to perceive it as a 3D image or is the pattern in itself all there is to it? If it requires reconstruction, where is the final reconstructed image located?

>> No.7186932

>>7186923

The pattern is the image. The thinking about the image is different parts of the brain that fire off via a kind of chain reaction from the image. Different parts light up in response to different patterns, so you might respond differently to a picture of tits than to a picture of gore, but this is mostly preconscious "thought" that may or may not enter your awareness.

When you thin about the image later, or even when you dream about it, the same exact pattern in your brain will re-emerge, exactly as though you were seeing it (more or less, our memories are actually fairly unreliable reconstructions from "clip art" rather than the photographs we generally think of them as).

Also there's no holographic 3D shit going on in your brain, that poster is a crackpot. There's legitimate attempts to reconstruct visual activity with what you see and it requires heavy processing which wouldn't be needed if you could just lift the neuron activity image out of your visual cortex.

Yes, if we could read the output of most of the relevant neurons.

Other than the scanning problem, another problem is we don't know exactly where the "neural correlates of consciousness" are yet. The visual cortex may not be where our sense of vision is (according to Christoph Koch). Though if we read the neuron output in the visual cortex, we'd probably get a close approximation of what we're concious of visually.

That's absurd because their "interconnectivity" can't form the visual field anywhere. Since we see the visual field like we do, it must exist (somewhere) in the exact form we see it in, otherwise we'd be perceiving something that doesn't exist. If that exact form isn't in the brain, there are no other options left and it won't exist at all.

I've asked /sci/ many times what space exactly is, as a phenomenon, but all I get are non-answers because it appears to be an impossibly hard question. How does one even study space?

Though when you think about it, if space was in any sense physical, and involved energy, it'd mean infinitely increasing energy since space is expanding, which is silly and unlikely.

Not *directly*. The subjective experience itself doesn't burn or use up energy besides what the neurons etc. already do. That's pretty common sense I'd say. Of course subjective experience is somewhere in the information flow between neurons which uses chemical energy etcetera, but that's not the point.

Existence is a complicated concept, but there can of course in some sense exist things with no energy or physical existence at all, such as numbers.

To physically exist, I think a thing would have to have energy, yes. I can't think of any counterexamples.

>where/what is the energy that allows for the existence of our sensorium? Is it just spread out all over the brain as electrochemically stored energy? How is that energy so precisely pieced together for the observer that, for example, the visual field appears as a completely uniform entity?
Surely our consciousness is contained in the universe?

I'm not 100% sure this even makes sense. I think you may be equivocating between different senses of "exist" here.

When you read this line sci, you should know you're getting trolled by a pothead.

I asked the question because I very strongly think that thoughts and perception HAVE TO use energy. There is nothing in the phrasing that would suggest otherwise. Also in every subsequent comment I've posted, I've made it apparent that I'm asking the question because I want a clear physical basis for perception.
And you think computers are relevant here? They're not because they aren't conscious and can't perceive anything. An analogy between the brain and a transistor-based computer is rarely a rational one.

I don't want to accept the notion of a virtual space containing our perception in the exact form that we perceive it in. Why would our consciousness as a sole entity be so unique that it has its own "virtual space"? The concept seems just too metaphysical.

This is the fucking problem right here, your question requires thoughts, perception and consciousness to be individual, wholly unique metaphysical entities. Which there is zero supporting scientific evidence of. Everything we know points to animals with brains and nervous systems being nothing more than complex input output machines. When you get to small enough animals like insects, their behaviours are simple enough to be modeled by computers.

Before asking your dumb ass pot head questions, prove that consciousness is an entity of itself.

When I observe an object, there is either a direct physical mapping of it on a surface in my brain or an indirect physical mapping of it in the connectivity of neurons or both.
In the latter cases, how do you avoid perception being in a way detached from its physical medium? I'm talking about the precise form of perception that we experience as the perceivers. If it's a bunch of connections that don't themselves physically build up any of the observed geometry (or other form of perception) inside the brain in a direct manner, how come we perceive it that way? There is no other possibility than it being an entity of its own that emerges from the neurons' connectivity. This is something that I don't want to accept because as we know, only physical things exist in the universe. It's not enough if the neurons are physical, the product of their functioning (our perception) should be physical just the same. There shouldn't be a discrete entity of consciousness, just like you implied.

>direct physical mapping on a surface
This is a pretty big assumption, only sight is kind of partially mapped on a portion of the brains surface as shown by optical implants and even then I think that was an adaptation of the brain to the way they attached the electrodes.

>indirect physical mapping
This is what it is, just like in a computing machine.

>precise form of perception that we experience as the perceivers
Here it is again, you are assuming that our consciousness is an entity and that it is seperate from perception which is also an entity.

What do you define as a precise form of perception? Because it is anything but precise, before your brain even begins to register fine details from your senses, they go through parts of the brain that quickly search through the incoming information and associate patterns with known physical phenomena. For example if you were to quickly take a glance at a room and then turn around, you might not remember specific colors or textures but you would remember familiar objects like tables, chairs, windows etc. This is because your brain processes information in a parallel manner and there are multiple pathways from the areas that process senses to the areas that are used for thought, some pathways are faster than others.

Also how do you explain memory, imagination and what happens when you day dream? Your external senses are blocked out and your brain begins recreating sensory data from memory which science has shown is not stored in an organized manner in the brain.

>something that I don't want to accept
Language like this has no place in science.

You have zero background in what you are asking and are making a shitload of wrong assumptions; if you really cared and weren't just here trolling then you would have done SOME kind of research into neural networks and artificial intelligence.

Cont'd.

Also read up on the chinese room thought experiment. If an operator inside a box is able to respond to your stimulus in a manner that mimics an intelligent being, how are you able to say that it is not conscious? How do you justify your idea of precise perception in the context of an intelligent machine? A machine that is able to learn works on reconfigurable circuitry; it's 'intelligence' has no coherent mapping in space and yet it uses energy to work. Rather, the flow pattern of energy is it's intelligence; why do you think it is any different from humans?

What does that mean? If you weren't observing the universe it wouldn't need to be. Duality is that the universe observes you right back, if it didn't the reason of your being wouldn't exist. People have a tendency to believe everything they learn is fact because it's source is supported and most will blindly accept that type of learning is truth. The laws of nature have a leg to stand on. Inertia is constantly overlooked because people like to think they understand something far before they've even grasp it so they can jump into something they'll aquire a loose understanding and so on. Ist law- nothing moves without an outside force acting on it. So what moves you. To say inertia is true and that we motion ourselves seems arrogant to say the least when we're aware of how little we actually know about who , what and where we are. Even more outrageous is how the laws that govern intrinsic value have no authority over the quantum universe. People argue about how their eyes work and their senses work to perceive their material world. Perhaps maybe this is just a great way for the much larger picture to observe and perceive itself and for some reason in this infinite expansion we like to believe it's about us. The eye does a job for the I. If you look up the range of what it sees, you'll learn it's a small percentage of what's actually present. Space isn't empty but individual perception is running on fumes. What's perceived as the emptiness around you are trillions of particles creating the force that governs life as we perceive. The paradox is the force doesn't abide to the laws it bestows.
