Memory is one of the most complex processes of the brain. Structures and processes involved in the storage and retrieval of information are necessary to exist in the world. But how does it work? Let's find out.
The best kind of memory is nostalgic memory. There is nothing like a fond remembrance of something which leads to a warm, fuzzy feeling. It just kinda makes you smile.
And there is nothing quite as bad as remembering the remorseful things you have done or haven't done. That feeling of "I should have kissed her when i had the chance" is soul crushing, life ending, apocalyptic.
I barely have good nostalgic memories aside from listening to old songs. May be I am not old enough(22), or the fact that I got through my childhood without amazing memories. But now everything is going right track may be 10 years from now I might feel good nostalgia about today.
@@GunwantBhambra simple thing like enjoying listening to a radio fm with amazing music, the voice of counting down the days before new year is nostalgic to me. Now nothing really makes emotional memories (or I'm exagerating, anime does)
I completely agree because according to the video long term memory is related to feelings. Memories of days, months, or even years ago are about something that you heard, smelled, tasted, saw or felt most of the times, and of course, it might make you feel well or bad, smile or cry.
I completely agree with you! There’s nothing like remember what your life has been, because that’s exactly what make us who we are. That’s why I think one of the hardest illnesses is Alzheimer. Imagine yourself living without any idea of what you have done, who were around you or even nothing about yourself, it would be a nightmare.
@@geojoseph Not at all, since we still have no clue how memories are stored after watching this video. There's gotta be some genius engineering at work when it combines all of the short-term memory into long-term. But even with our tech we can't figure out how it's all done.
Sychius studying more might help. It’s possible that when the memory is sent to your hippocampus, it notices that the memory is not being recalled enough to be sent to long term storage. This trigger is different for everyone, and some people need to recall the memory (study) more
@@eveecat Olivia Russell I was going to say the same thing, and as the video states, our perception of the world differs, and I was going to add onto your reply. The reason why Sychius is having a hard time is because they're not studying enough, it's like learning to run a marathon, early on you hit the wall at 3 miles, then your wall becomes 5 miles and so on. Sychius stops studying when they hit their limit / wall, it's a very similar feeling. Your brain stores memories of how it should react, adapt, or handle the chemical process needed to sustain your body as you run. So you stop when you get near the wall, one because it's a different or new chemical process and two because you have not made these memories before. For example; the memory stored in your brain, will slightly differ when you run for 5 miles versus 10, and the memory of how to use your stored fat as energy, get rid of lactic acid, heart rate control, more efficient oxygen delivery to the muscles, etc. will differ at different duration of time spent running. Although not exact, studying for different duration of time will also have it's own differences in chemical process. How long can you endure making new memories over and over before hitting the wall, because that chemical process does require energy and your brain has to also figure out using fat storage to feed the brain past the wall. (I'm sure if I wasn't so high I would of made my point smaller and clearer)
@@Mandolin1944 The comment you're replying to is from about 6 years ago, so be grateful I'm older and less vitriolic than I was then. Glass houses chap.
Well you are remembering that time that you thought about that thing. I can for example remember a funny limerick i thought about the other day, but what i'm actually remembering is the moment i said it to my friend, so it's not just the thought alone. There is a reason you should write good ideas down, because if you just think of them and do nothing else, you will forget them.
i dont know if thought can be categorized as the same as any other sensory feeling.Bcoz other sensory feelings depends on what the stimulus is.If you get punched in your face or get a burn, you will feel pain,not pleasure.If you taste your favorite food,your tongue senses but it cannot sense a taste that isnt in the food. But thoughts can be anything. It can act both as stimulus & response to the brain. you can imagine things that you have never experienced.They can form patterns & be meaningful
I sometimes remember what i thought about an experience, but not the experience itself. For example i remember if i liked some food i tasted or not, but i don't remember how it actually tasted like.
The thing I want to study so badly is how your brain remembers chronology of memories. The feedback loop to know where you are in the past is so freaking interesting.
Contextual cues, when you try to remember when a memory happened, your brain is going to analyze like what the temperature was that day, or how the weather was like, then based on the cues it will be able to make a conclusion, about when the specific memory happened
It's IMPOSSIBLE for the neuronal brain to act as any sort of storehouse of memories. How can there be storage when there's absolutely no RETENTION! Neurons are cells specialised only for the purpose of conducting and propagating signals pertaining to sensory data and motor commands. The two structural features of the neurons that make them unique are the dendrites and the axon which enable the neurons to behave in the manner of wires through triggering and "carry forward" of the action potential. There's absolutely nothing in the morphology and function of the neurons that suggests storage of signals. Networks of neurons thus behave merely like relays and dominoes conveying and propagating signals up and down, routing and rerouting the data. Therefore it's a BIG LIE propagated by the neuroscientists clinging on bigotedly to the materialistic ideology that the brain is the storehouse of memories. It's simply impossible. _There's simply no structural and functional support._ The brain is actually a data communication network with billions of cables insulated by myelin! It's definitely NOT a hard disk! The signals rippling through the neurons are themselves *extremely transient*. A neuron is repolarized (returns to its original resting state) within milliseconds, making even working memory impossible! The signals are actually actively "deleted!" Given these facts, the materialist neuroscientists should stop fooling the gullible masses. The non-specialist persons should also educate themselves about the structure and working of the neurons and determine the truth for themselves.
That was good explanation of the rather involved process of the hippo-campus; collating and indexing of short-term memories into long term memories. Great video, no wonder this channel has so many subscribers. That was really well done.
If memories are stored chemically by how neurons and molecules are arranged, that means there must be a limit to how many memories one can store. I wonder if we will ever discover that number. Also, does that mean, theoretically, memories can be copied by arranging the molecules and atoms in a neuron to the same way they are arranged in someone else? Can we know exactly what specific neurons are responsible for a certain memory in an individual too? Lots of questions, I know, but it's too interesting.
Apparently we have over 3 trillion neurons and their arrangement of connections can be so complex that there isn't a computer or network of computers in the world that can mimic the unique connections that the brain can make. The analogy is we have more neurons than the observable stars in the universe and we have over 10 times magnitude of that in terms of the types of connection patterns a neural network can make.
There is a limit, but it's unclear what that limit is. What we do know, since we have such a huge capacity to remember in our tiny biological memory modules (brains), is that it's possible to have such a capacity in at least one form and therefore most likely we will eventually be able to replicate this synthetically, and perhaps even exceed it. Not only that, but since biological brains are constrained by the skull but synthetic versions are constrained only by whatever substrate we create them in, it is possible to create massive memory modules, as in the size of a small planet (at that point the distances are so big the speed it takes for information to propagate from one end to the other through the substrate is getting pretty slow and therefore not useful). Also you could just link many biological memory modules (brains) together like we do with computers today, with a neural lace and internet. This is the future of human memory capability.
@@PresidentialWinner Right. Unfortunately you overlook the simple question of "unit". What are the assumed neural units of A memory? How many neuronal interactions are needed to have a memory of X? Are all X's the same (landscape vs name of bird?). Oh those nagging little questions that are necessary preconditions for all our lovely neuroscientist pronouncements. BTW: I suppose we could clear up much if we first could specify what a memory consists in. But then, why let conceptual clarity stand int he way of progress?
I am 74 an want to get back all those brain cells I destroyed having a beer here and there,,, and more along the road of life. I have so many what does it matter I would say...back then. IT matters now......
One of the things I remember so well from one of my university courses (I'm not fancy, I'm Canadian lol) is that thing when you try to remember something and can't and then 3 months later you shoot up in bed and burst out "It was a llama!" or some shit, your amazing brain was just scanning away still working on its task the whole time. Just. Fuck.
Honestly I think memories are broken up into different pieces because many times I'd try to remember something, but only remember it after going through all of the senses. Also Reddit has a community called r/tipofmytongue if you're struggling.
Had Lyme disease badly, lost my short term memory for several months. I coped with alarms and notes. Couldn't remember my clients' names but recognized a face and the business they owned/operated. Eventually my brain repaired but that year is barely stored in my memory, I've had to memorize what I know happened to me during that time. Fun side effect of Lyme: I lost the ability to type for a time, the muscle memory in my hands. First my hands operated backwards and then failed completely. I got that back though... obviously lol
Well, with Alzheimer's, the reason a person forgets things are because of neural pathways breaking down. P.S. This means those memories are gone. You wont get them back, regardless of the magic potion vultures try to pawn off to you in order to take advantage of your grief. But, there is SOME form of regaining memories. If you can reverse the degradation of those neural pathways, and stimulate the production of new ones, you can trick the brain into thinking it remembers things. Don't get confused, the actual memories are gone; but you can tell someone about what happened enough times (if the process is reversed) and they will start "remembering" it. What they're really remembering is your description though - and this isn't just Alzheimer's. Healthy brains are tricked into "remembering" things all the time. Our memory isn't perfect, and is highly suggestible. That means the short term kind of rewires the long term. If you have a group of 20 people witness a crime, in plain view, and ask them to describe the criminal - you'll get 20 different answers. It's partially because, in your long term memory, you already have a pre-concieved notion of what a "criminal" looks like, and your short term memory tries to fill in the blanks; but odds are you have no short term memory of the event by the time you're asked. So the short term memories you're using actually come from pretty much right on the spot from where you're at; and you'll even forget most of the descriptions you gave moments later. Memory is fucking weird.
Just watched his video on memory in the brain which made me wonder if the brain has a database management system like "MUMPS" managing a bill of materials (or even bills of Bills of Materials - overlaid BOMs with extra key "Type of") I had a brief discussion once with Roger over binary pairs. Maybe this too should be revisited. Though another clue may be twined binary pairs, since DNA/RNA has TA GC pairs which I have always thought of as being another dimension more powerful than 0 and 1 therefore provide the basis for a more powerful organic computer processor.
As an enterprise system architect designing highly available systems, I can relate this to my daily job. Caches, Indexing, partitioning, Read/Write replicas, CAP theorem :D
When my father died im so freaking don't know what happen to are life, i just have 2 hours of sleep and trying to not feel sleepy because i have to entertain my father's friends. And one week past i have a powerful brain it turns to pictograpic memory and every time i work i am not feeling tired, i remember everything and i don't feel sad and happy. I don't even daydream, im not even feel hungry or whatsoever. Why is this happen?
Do you have any references for this :) im looking into memory study for a project at the moment xD so even if this video is a good explanation, i would need to document that it is also a valid explanation.
I remember from when I was 3 years old, I was crying, and my cousin cheered me up by making a funny voice I remember what he said but it’s too hard to write, but what I don’t remember is why I was crying.
yeah, the only thing I took away from this video. I searched "how the brain moves new information from short term memory to long term" as I am a 65 y.o. left-handed male trying to learn FSI level 5? Korean. I don't recall him saying anything useful in my learning process.
Actually ya kinda hit the nail on the head with saying info is stored in indexes ...personally I say libraries by volume .... Like books and as you too mentioned and like books that go unused over time the info/book degrades as you've not widened the neuro pathways by routinely extrapolating the data (referencing the index/reading the book.....ya get the idea. Great vid! Was kinda odd I landed on this video but regardless ... Liked and subbed as a creator (trying) I know it helps ya channel and I hope others too like and subscribe as content like this is very important and demands further research as we know more about the oceans and space than the human mind. Crazy truth. 😇
Cool but the important part is at 2:26, and you don't know it :). Probably no one does. You explained how the brain organizes short term memories to create long term memories. You didn't answer what the title asks.
The channel is improving but I do think that the introduction to the topic is usually quite long. And it would be nice if you explain it a bit on a technical and a detailed level too. You kinda graze through it.
Lol my Brain HDD has like, 100 PB of storage! I remember such tiny details from MY WHOLE LIFE! I remember things from the day when I was 4 years old and I peed myself while screaming at my mother, when I saw a car light pass by our window in the middle of the night when I was 4 years old, when I first tasted pizza, etc...
Hold up.... If we somehow develop something that can read the molecular structure of each memory..we could in theory translate all the memories someone has after they die ? An in turn allow us to reconstruct that brain artificially and in turn answer the long question of is conscious physical / chemical?
It probably doesn't overwrite memories, otherwise conditions like Eidetic memory wouldn't exists. I wonder what the maximum storage for such a person is, Is there a limit to memories?
looking for storage in atomic level...but nowhere else. Short term seems somewhat Hemrof and Penrose model of micro tubules but still uncertain. memory is also non localize eg out of body experience and NDE. very amazing it is there hiding
Yes,I remember that I have watched that video with Dr.Penrose talking aboutthemicro tubules,and I have understood very little. My level of understanding is low but my memory level is high 😀😄
To get the idea how small a molecule is, imagine shrinking yourself to the size of water molecule and attempting to walk across the us penny. To cros side to side it would take you guve or take 400 years.
If memories are retrieved in form of electric impulse how r v able to understand tat a particular electric impulse is to remind a particular thing? Pls reply
So basically your brain is just a bunch of nano sized hippopotamuses going to college. My hippo's like to party more than going to class, which can lead to trouble.

This is not an exaggeration in anyway. I have DISTINCT memories going back to me being 2 years old. But at the same time I misplace my keys/phone/wallet 3-4 times a day. I have lost 9 cell phones but remember all the text and numbers. I can recall sentences said by someone word for word from like 15 years ago, but lose my wallet at the same time. A good metaphor would be I have a long term memory of elephant but the short term memory as a gold fish. Can anyone share a hypothesis or link to help me out? Also, I never forget a face NEVER, but when someone first tells me their name. 5 out of 7 times I will not remember there name.
Ever thought why brain didn't evolve into something like memory could be transferred from mother to baby just like genes so the young one will face the world better with its ancestral experiences ? That is because ultimately the existence of life doesn't totally depend on how the past was but how the future is going to be.
I'm reviving this comment because nobody replied. I too wonder this but then again if you take an animal at birth and raise it captivity why does it still show instinctive behaviours
I've heard several times that mothers who experience trauma as significant as Auschwitz leave a genetic imprint on future children conceived. I don't comprehend these things so I don't know what to think of that statement. I try to research these things but without comprehension I could fall for anything.
@@connormarlow7557 Memories are grown into the animal when inside the womb, just like physical features. Basically a minimum set of memories (instincts) to prevent death. It's the first initial implant of artificial memories by the animals genetic code, stored in special neurons (no proof, just a guess). Each species of the animal gets the same copy of instinct memories unless there is a genetic mutation.
I think my memory is working against me I remember things that are unnecessary and useless but freeze up when I’m in an exam not to mention it keeps bringing up all my mistakes especially when I’m trying to sleep n whenever a good memory pops up it jus scares it away by remembering some stupid thing I’ve done. Iv come to realize that my good memories are Very short term n the bad is long term probably trying to psych me to be better. So it’s all good. Also I’ve decided that after much consideration I believe hypnosis is real. Because the brain stores memories and with the proper skills n technique memories from the past can be manifested. Jus
I don't believe there is a short term and long term storage center in the brain, it makes no sense. Working memory is not memory at all, it's conscious thought. Long term memories must be stored in the sensory systems responsible for perceiving them in the first place, i.e. images from the eyes are perceived in the visual cortex. The hippocampus might decode memories but no way does it store them. Memories are felt as genuine experiences, not accessed and played back through a sub system, it's because the brain is like this that we are able to achieve consciousness, because everything works in parallel and is accessed simultaneously through firing neural networks.
lets assume that i had dreams for last 20 years now my brain randomly plays same dreams with different characters and minor changes and i am aware of it that i am having the same dream then is my brain actually accessing that currpted data again🤔 if it does then why it is doing so?
