Very curious to see where that first one goes with hallucinations. I wonder if they're lookling at sleep at all (probably hard to do) since we seem to believe all our silly hallucinations then. In sleep paralysis especially it's interesting to me the things I'll believe I'm really seeing. Different types of drug trips too... be lovely if they were able to look at the variety along witth disease. Suppose the change over time of day too... I am much more likely to hallucinate when I get tired assuming nothing else is at play.

for sleeping, only part of your brain is conscious and most bits to do with reasoning are unconscious so you don't tend to question things. and if you do, you tend to wake up or wake into a lucid dream. however even in a lucid dream where you are aware you are dreaming... most people can't read a book or tell the time because those specific parts of the brain aren't turned on.

Im usually not phased by my dreams and it doesnt elicit much of an emotional response when i do dream. Like ill wake up and reflect for a moment how unique the dream was (movie-like). But during the dream i dont experience strong emotional responses. I used to as a child and teen as a result of an irrational fear instilled into my mind about demons. Once i came to the realization its not plausible, i stopped having nightmares. That was until recently, where two specific dreams manifested from some subjects id watched in the day. One being serious abuse occurring in the army for females who are murdered and then its claimed to be suicide. Ended up dreaming a male spiked my water and while i was laying in my bed i heard him walk in and stand behind me but i was paralyzed and unable to move or open my eyes. I realized what he had spiked me with was going to kill me and he was going to do not so good things while my life ebbed away and i could do absolutely nothing. I wanted to scream for help, for anything, but i was entirely paralyzed. Another dream just yesterday i was driving in my car to my job and i got into the parking lot lane to find a parking space and a person walked past the front of my car and as he moved past he pulled out a gun, aimed it at the glass in the front of my car directly pointed at my head from a distance and shot me in the head. I woke up with my heart racing because it felt so incredibly real. This dream happened i figure because my sister told me about a guy with road rage showing off his gun from his window (ghetto area). I mean for YEARS i didn’t experience serious responses to dreams until recently those two. It’s kind of weird how now of all times for some odd reason a few dreams have managed to be surreal after so long of being detached from it.

@@cynical-4649 This feels like triggered by some trauma of sorts. I face emotional dreams all the time. I believe that these dreams are just warnings your brain reminds you of so that you remain cautious. If someone can kill and then hide it as suicide; then, what prevents them from killing you and covering it up as a suicide too? That is what your brain is probably concerned about. I also had an irrational fear of demons. I still believe they exist, but I doubt they want anything to do with me. I am a mix of very emotional and stone-hearted-->My dreams half the time tend to be emotional and hyper-realistic-->They are typically about someone from a family ending in a tragedy of sorts and while dreaming I would be crying and panicking-->Although, it is sometimes annoying for some reason my concern over their well being and longevity sometimes enables me to enjoy the crying times because it makes me appreciate them more when I live with them/talk to them/reminds me to spend time with them... I think if you want to understand why... All you have to do is find a great psychologist and ask them to interpret your dreams while providing them with your context. If I as a non-psychology student could interpret your dreams and mine well, I bet an experienced dream psychoanalyst would do it better if they truly care about their patient's wishes

8:26 - excellent admission.

For the first one. It seems like it's not just a matter of the Vividness of the imagination that leads one to think that one is dealing with something real, but also the odds that what one sees could be real or imagined. If one starts to see a green goblin out of nowhere, something in us will assume hallucination not reality regardless of how vivid the green goblin may to be.

I love the findings which can be very practical- I would hope that we never increase our natural cycles of timing to develop people. The world is already fast enough as it is. We do not need to hasten our own mortality. Production of supplemental and genetically modified cells for therapy is the backbone of any fantasy lore with healing. If our bodies can adapt to healing faster, while stabilizing and retaining theses cellular sequences, we could accomplish more beyond the limitations of flesh and bone.

For mitochondria I really think looking into the sodium potassium pump would help with the study? Cuz isn’t that also involved with the regulation of energy/ dna encryption?? I could be a broken record. But I feel maybe is similar to synaptic functions.

Amazing~

I would argue that the setup was so 'fine' that it was 50/50 that a subject would report "seeing" an image on a screen vs not seeing the image; even if NOT told to imagine anything at all. What I would suggest is to develop a more concrete test for imagination to test this hypothesis.

I love this channel you learn a lot

On the 1st one; kinda interesting cuz when I trip balls I see heaps of stuff happening but remain fairly certain it's all imagined, does the threshold then disappear because I'm conscious of my imagination or is the 'gradual meter' so to say heavily moderated by the perceived probability that something is real? Or both? or something else? Good stuff

Thank you scientists. May dogma fizzle out of our cultures and accelerated scientific progress ensue.

sometimes we see some patterns like a sketch or something when seeing a blurry or noise image. Like say we see some cracks that look like a face or something, this sometimes when asked to someone else they may not see what we see. So even though the noisy screen does not display that lines someone might see them (our brain might be overlap them onto the screen). Am i right?

The "internal timer" you refer to is its Frequency, use the frequencies opposing "internal timer" to speed it along. For instance, using love to clear hate and harmony to heal chaos.

Yes Djikstra, that is because reality is sense perception. Imagination is cognition of sense perception. There is no reality, but sense perception and cognition, which is why they act the same way. Cognition makes sense of sense perception, but it is also free from sense perception, which allows imagination to exist. Cognition is thought. So cognition of sense perception is imagination. Does this make sense? Gotta love these scientists.

You know that thing when you look at a bright light and you get a sort of dot or blurred line in your visual field that often looks colored or dimmed, that effect has absolutely nothing to do woth anything in your eyes, and if you train yourself you can make those effects apear, disappear and change even when you didn't look at a bright light, this is because it is essentially a lagging adjustment your visual cortex makes to male you see contrasts better it is hard to do if you cant produce images by visualisation already, but it can be done, one way to see it vividly, is to use a decently strong led lamp and look straight ahead while you drag it across your visual field, while not following the light with your eyes. This produces a very easy to see light spaghetti, in a dark room you can see it very easily, and it is not that hard to train yourself to make it entierly disappear and come back at will. This effect is not about visualisation in some more obtuse way, it is really like seeing it, and it is pretty much the same effect. When you have learned to do this it can also be done without the might but it is more difficult, but with practice you can see and imagine images in full detail as well after a while, but the more detailed the more like dreaming and the less like seeing it becomes, i suspect that this is not necessarily about different parts of the visual cortex being used, more so that when you start seeing more detail the input from your eyes become more and more ignored and so the sensation of seeing actually feels different as well.

i am diagnosed with schizoaffective disorder and ive always said if i imagine that i will see something i ALWAYS ALWAYS see it, so before she even mentioned schizophrenia i was already thinking about bringing this up to my psychiatrist

Interesting stuff 🤔

This particular test wouldn't work with people with aphantasia, but fundamentally it's a completely different thing. This talks about "once the brain generates something, how can it tell if it's real?", but it says nothing about the actual process that allows the brain to "make things". In the case of aphantasia, they cant make *images* in their mind, but, for example, they can tell their inner monologue is not a voice coming from outside, so the process of reality treshold very much does exist in people with aphantasia, its just that not as many processes use it

Thanks heroes, God bless good friends , great noble people, amen

2:15, wouldn't imagination when specific objects are shown activate areas in the brain responsible for recall of that object? (like a banana) Conversely wouldn't being shown faint lines cause the mind to try to make something of them since they are not necessarily specific objects (like staring at clouds or a patterned wall for a very long time we can imagine and see things that arent there but are relative to the information presented)? I'm just curious if the perky effect has been thoroughly disproven or if these are 2 totally independent phenomenon?

This can help in the treatment of the healing process of different types of damage and control of different diseases 👍

Have any breakthroughs been made regarding longevity?

I have to say, from the 3 "breakthroughs" only the cell-acceleration thing sounds like something that is actually new knowledge. The microbiome thing is known for decades now too

It would be interesting if there was also biggest breakthrough in environmental science and ecology

Very interesting

amazing

"You are the average of 5 people closest to you" have never been so true

Do you know what this meant, we don’t need to build large Language models for specific function for imagination or perception. I work with autogenerate agents, where each agent is given one task and their responsibility is to do that specific task. In this case, one agent describes what it should imagine. The other agent creates image out of it and send to the original thinking agent. This happens back and forth, but in our mind this communication happens so fast.

What is "risperidal" ? (Linnaean classification) What does it eat and what are it's metabolic products and (pheremone-like vs excreted) byproducts ?

It seems to me the way we distinguish between imagination and reality is relatively simple: we ask other people or look for feedback from other sources. It's why we ask " Are you seeing this? Did that just happen?" when something unexpected occurs. I think when you see or hear things that other people deny, your response will depend on your socialization (i.e. how much have you been taught to trust your own experiences?) and the relative intensity of the experience (i.e. did you just glimpse it once or is it ongoing?). I think the fact this is more of a spectrum makes a ton of sense to me; kids have a far more fluid idea of imagination and reality, but are socialized over time to discount the more imaginary aspects of their inner worlds and to distrust their own experiences. Women especially are socialized to question their experiences and discount things that have happened to them. If someone has persistent hallucinations, this may be distressing for many reasons, but one of them is probably that you can't make your internal sense of reality match up with what other people are able to confirm.

And that's not even to mention anthropological studies of peoples who believe in the supernatural, where someone reporting that they'd seen a spirit would be a completely normal thing to hear. In that case, a sensory stimulus that we might call a hallucination, their society would consider perfectly real. I highly recommend the book Don't Sleep, There Are Snakes for a perspective on such a society.

As long as discoveries are for humanity and don;t have a price tag.

This is so cool

Nice, just wonder who is the designer created those beautiful graphics/animation (like the brain and banana)? Would love to know them

Thanks Cornell biologist

I wish there was a recap of discoveries in earth and planetary science:(

I think it is more of a disease originating in our social apparatuses, and the behaviour and stressed states create a scenario where you close of and can begin sort of dreaming while awake in a sense. This doesn't account for everything, but i think the anti social aspect is really the more defining trait of that particular disease and we habe many predespositions that can make it easier or harder to hallucinate visually or audibly. Have you ever heard of a sick person get hallucinations that are abstract and not at all anthropomorphized innterms of agency or narrative prior to showong other symptoms, i havent reviewed a lot of cases, but i think the anti social and mental isolation is the primary aspect and hallucination can happen like it can in any healthy brain, but people have different predisposition to enable healthy hallucination so to speak.

the question they're trying to answer is different though. they are trying to see what happens in the brain/on a molecular level, not to answer why hallucinations exist.

They started off with the Perky effect and how the brain can tell the difference between real and imagined sensations, which is an amazing idea. But I'm not sure how useful that is in the real world, other than just being cool to know.
