      This is also the reason why after a head injury/traumatic brain injury some patients fight us.
      The brain in self preservation mode will fight anyone who comes near the body because it doesn’t want to be hurt anymore.
      So you could just be trying to assess for injury/take a BP/check for a pulse/or just giving a reassuring touch and the brain will send signals to fight of the perceived threat.

    story 11 is super accurate, i have depression and anxiety (+ a couple others i will not get into rn) and it does absolutely feel like your brain is separate from your body and reality sometimes. it can be incredibly distressing and can make life a living hell. mentally ill brains love to come up with the worst possible thoughts and images and feelings. thank god we live in a time where you can be treated for these things, i can't imagine what it was like to live with severe mental illnesses in like, caveman times. i would not have survived as long as i have. it's a cruel world but sometimes the most cruel part is your own mind

      Edit: it's a thing where religion makes them believe that God is the fix to mental illness or you go to the mad house.
      Edit[the sequel] : also there aren't any pro-choice doctors or psychologists where I am because.. oh well.. religion is against queers like me :(

    Fun fact: Not long after was born, I was suffering from an extremely severe asthma attack and nearly died on the spot but my father managed to convince doctors to take me to a different, better hospital at the border of Tennessee and Georgia. They used a prototype machine that wasn't even tested beforehand on me to get me to breathe normally again and it worked, however.. They were too late to save me from significant brain damage. I suffered rather severe brain damage and doctors literally told my mum that I'd never be able to move and that I was effectively a vegetable is pretty surprising since I am able to move, talk and think just fine so it probably unsettles doctors as well when I walk in. I do have some minor motor skill issues, but that's it.

    I am autistic. One day I tried to explain to my sister exactly what I remember, translating the images in my mind, and the sounds…. And some extent lighting and color. All of this goes into my memory and how I recall. When I told her that I have to make up logical bridge between memory snapshots. Even when it plays like a movie, it will jerk as if somebody had cut something out. Also, these memories are less reliable and I know that. I’m always reviewing my memories to see if I’ve added something to it that wasn’t there when it was first was re-created. For many of us that are autistic. It is a gift and something we treasure. It has taken me many years to learn what a gift I have. I was born in ‘47, diagnosed when I was 50s: for referance

    I can talk about story 22, since I live with it. It's just straight up children don't have coherent personalities. The personality merges at ~9 years old, however, if severe and/or repetitive trauma occurs, the personality cannot integrate, leading to different facets of personality known as alters (which, as I've heard, means alternate state of consciousness). Basically, the brain believes that due to trauma, it must keep the facets separate to survive.

    • @LunarCatKan
      @LunarCatKan Рік тому +22

      the thing is, while the literature specifies a thing or another, accounts from all over have determined that there really aren't any hard limits. in fact, that "coagulation" can, just by natural causes, have multiple "centers", leading to a non-DID manifestation of a phenomenon better known as plurality, one that isn't caused by trauma of any kind.
      in fact, I feel it's somewhat close by to extra organs and whatnot, just at the mental level.

    My mother had a stroke while she was doing cardio karate(think tai-bo). One artery going to her brain just plugged up. The doctors said when they see stroke patients with this kind, they are corpses. Doing a scan of her brain they could see that the blood vessels on the side not cut off from blood stretched over to the side that was lacking. Which helped keep that part alive until her artery could be unplugged. They think because she was being active with the cardio at the time of the stroke it gave her vessels the ability to do that.

    The human brain might just be one of the most complex and interesting things in the world. Our brains have two halves that analyze the world differently, and decades ago severing the connection between those two halves was done to "cure" seizures. What was discovered through those split-brained individuals was that those halves of the brain essentially have their own consciousness. The eyes are actually connected to a separate half of the brain each, so split-brained individuals can look at the same thing with each eye and reach two different conclusions.

    Liver can indeed grow back. In fact it is the only organ in your body with regenerative capabilities. Usually during a liver transplant, from the donor's liver one lobe (a liver is bilobed) is given to the recipient. Both the lobes in both recipient and donor grow back in time to 2 complete livers. So before you decide to be an alcoholic destroying that organ completely, think twice :)

      smooth muscles (think organs and veins/arteries) just do their thing.
      they communicate with the brain to some small degree but the brain doesnt get to decide much.
      skeletal muscles on the other hand communicate extensively and it goes both ways.
      sometimes the skeletal muscles are like " hey brain i grabbed some random thing that smacked our left palm." and the brain is like "wait wut? what is its?" and you look at the baseball you accidentally caught
      (instinctual reaction)
      sometimes the skeletal muscles are like " hey brain i want to use 100% of my power and use our heel to itch our upper spine" and the brain is like "NO! HOW MANY TIMES DO I HAVE TO TELL YOU THAT 100% TEARS YOU APART? you can try with 35ish% but im telling the quadtriceps about this." and then you have a involuntary upper leg spasm (involuntary action)
      sometimes skeletal muscles are like " im gunna grab this hot iron handle" and the brain be like "not so fast!" and you stop midway to grabbing the hot pot handle
      (second guessing a voluntary action)
      and sometimes the skeletal muscles ARENT suicidal or feral and be like "we grabbing the fridge handle" and brain be like "yeah, let me predict the process so the rest of us know" (voluntary action{typical})
      so basically the same as what you said but the muscles have the first say.

    This isn't a creepy fact, per se, but it's definitely not well-known outside of the medical field:
    *The gallbladder is, arguably, more useless than the appendix!*
    "But wait, doesn't the gallbladder make bile?" Nope! The _liver_ makes bile, then _stores_ it in the gallbladder. The gallbladder can concentrate the bile (which can lead to gall stones), and it will release the bile after you eat.
    "But wait, that's a function! So how is the gallbladder more useless than an organ with no function?" This is a two-part answer:
    1. You don't actually _need_ concentrated bile to digest food; it just helps to digest more fats. So, if you ever have your gallbladder removed, almost no part of your daily life will change (unless you eat a lot of fats -- in which case, going to the restroom becomes _very_ interesting...)
    2. The appendix has TWO purposes, both of which deal with the immune system! The appendix contains something called MALT -- "mucosa-associated lymphoid tissue". MALT contains T cells, B cells, plasma cells, dendritic cells, and macrophages -- cells that are important to the body's immune response. If any MALT tissue detects an antigen (the part of pathogens that induces an immune response), then it can both attack the pathogen _and_ signal the rest of the body to be on the lookout for pathogens! The second, and simpler, purpose of the appendix is to act as a reservoir for regular intestinal bacteria, so in the event that your gut microbiome is disrupted, you can repopulate with the bacteria that is beneficial to your digestive health.
    _Clearly,_ the appendix is much more important than we previously thought! The gallbladder, however, only has minor impacts to our day-to-day life and isn't _nearly_ as vital as we previously thought. So, it can be argued that the gallbladder is _more_ useless than the appendix!

      1. You have to take an absolutely MASSIVE shit within an hour or so from eating, and
      2. The explosion of shit is almost like diarrhea, except it's oily not watery. You're gonna go through a lot more toilet paper than you thought was possible, and you're probably gonna need baby wipes to minimize any burning from all the excess wiping...

As you get older, it gets harder for the brain to patch the gaps cuz the condition is getting worse over time. Eventually the brain can no longer repair and fill in gaps and that's when the symptoms actually begin to show themselves

    1- I still have some of my milk-tooth because the other ones didn't devellop;
    2- I have hypermobility and It leads some of my joints to being extremily flexible and even made me break a record in a scape room once, but also means sometimes my limbs will dislocate radomly so I have to put them back at place manually;
    3- my red blood count is just a lot naturally lower than most people, I had travelled all over the country so doctors can look for possible pathologies that can cause it or be caused by it, turns our its just how my body is made, it is so weird that even when I suffer something that should bruise it rarelly goes black and blue because there isn't enought red cells for it, still I have no problems with lack of nutrients or oxygen or cicatrization whatsoever;
    4 - I can move my ears, and not the "fake movement" people do by moving the forehead muscles, i not only have the vestigial muscles humans used to have to move the ears, but I also can move them individually in slightly diferent directions at the same time and in different degrees, also, I learned with time to instictly move then towards sounds directions when startled, just like cats and dogs do;

    I wanted to share something I learned a long time ago, this was when I was still in high school from my history teacher who was an X-Veteran. We learned this while going over the subject of the Holocaust when all the religious people were being locked up and killed by the Nazis.
    Apparently if you try to eat a lot of anything solid after starving yourself for long enough your stomach can bleed profusely from the stress being put on it and you can die from this. As we know the stomach will start to digest everything to keep the body alive that includes the matter and nutrients of the stomach itself weakening it to wear it can become extremely fragile and disgusting anything solid can damage it from the movement the stomach does to digest food. A story he told us was that after WW2 ended and all the religious people that survived were saved and the military that saved them tried giving them food and water because of how Malnourished they were but literally 24 hours after they did this over 300+ religious people or something like that died afterwards. The military got confused about what was causing this so they did several autopsies on the dead bodies to discover the cause and they couldn't figure out what killed them till a few doctors and nurses pointed out that the people that check still has food in there stomach that was barely digested and the stomach was profusely bleeding because of how thin the wall lining was. So realizing what they did they immediately told the rest of there soldiers to stop feeding them cuz they were so fragile from there entrapment by the Nazis it was killing them of they tried to eat. They eventually figure a safer way to provide nutrients to the people by giving them nutrients through IV Bags or either blending up everything edible and high in nutrients into liquid mush to build up the body and organ mass up to its natural mass again only letting them eat small amounts at a time till they believe it was safe to give them more to eat and eventually allowing them to build up there body mass so they can safely consume solid food again.

    Same thing with ny dad. Car rammed into his back (slow speed) and he kept having back pain for years after that but would just keep working and lifting heavy objects while working with cars. He said that the added pain of the lift would help ease the original pain (even though it was really just a distraction from the original pain obviously) but one day he got fed up and went to the doctor to get it checked out. They checked his muscles and he was extremely fit and got complimented on that, but when they checked his spine they were very confused as to how the heck he wasn't paralyzed. Four sections of the spinal cord at his lumbar region were slightly misaligned, which caused his muscles to squeeze and severely restrict those areas to be extremely thin. It was bad enough that the doctors warned him that there was a high chance he'd get paralyzed if he tried to get those disks realigned or something to that effect.
    I'm no medical expert at all, my only guess is that his "workout" all those years is what's holding his back together, as he's been starting to gradually get worse as he ages and can't work anymore. Like I said though, I really have no idea how he's still walking. The human body is fascinating...

    I would like to add on to the corpus callosum:
    - people who have this have a specific name for this. It’s called split brain for obvious reasons
    - with the experiments, it solidified what we know about the right and left brains but far more. It probably doesn’t need to be said, but to clarify, neither side is dominant. Both work together and severing the corpus callosum showed us what happens when they can’t.
    I’m one test, they would flash a word on the screen to only one eye and ask the person to say what they read. Showing it to the right eye, the left brain could say what it saw be it the word cat or a picture. When shown to the left eye, the person had to say nothing because communication is something the left brain specializes in, not the right brain. The right brain could not, throughout the whole experiment, say what was on the screen because that’s not what it does. Even stranger, it did know what it was looking at. If the word ‘phone’ was flashed, person would say they saw nothing but their left hand could draw out the word the brain read. Cool, right?
    - the creepiest thing to come out of the experiments was the realization that both hemispheres of the brain have their own personalities. The command ‘pick your favorite color’ could be flashed to both eyes and the two hands would choose separate colors.
    There is a lot more I could say, but I would highly recommend looking up videos of these experiments to see what I’m talking about
