What are your earliest memories?
i remember falling over during a reception play.. i was not happy
My earliest memories..i was approximately 3 yrs old (according to my mum) & i recall sitting in the dinning room, behind the door on the floor..and getting licked on my hands by a German Shepherd dog, named Kim. He was ginormous (of course it was me so tiny in comparison..)my mum said he was her neighbour's dog, and he idolised me,wasn't bothered about anyone else. He used to let himself in on a Sunday tea time, for leftovers from dinner! I fully understand & appreciate where my passion for German Shepherd's come from,and i have had them in my life since leaving home🤗 Definitely my earliest memory
Being taken to school on the first day by my mother. I was apprehensive and fearful of the maternal separation. I guess it may have been adrenalin which cemented that particular memory when I was about 4 year 5 months' old.
@@ThatMedic I cant imagine you not happy
@@toughdogproducts and a happy one too!
It's hard to wrap my head around the fact that all my life experiences, all the people I meet in my life, could basically just be stored as an electrical zap thing, and if I damage my brain in a physical or even emotional way I could potentially lose temporary/permanent loss of that
There's a quote I really like about brains too: “If our brains were simple enough for us to understand them, we'd be so simple that we couldn't.”
The brain is such a complex organ i wonder if we ever understand it completly. Great excursion!
One of the most interesting educational channels out there. Love the content !
That's really kind of you to say. Thank you!
i read the book the brain and something that stuck with me ever since is the idea that our brain matter might not be important, just what it does. so if we replicate what it does we could put our brains on hardware/software , pretty crazy to think about. even if that seems so far off, im glad we already know so many amazing things about our brain. and im glad we have people like you who inform us
This is such an underrated channel!!Like why is it not having a million subscribers!?..
Any channel with a million or more subscribers, it started with one.
It is underrated, because of that ignorant, annoying music in the background... if he would turn it off... I may subscribe!
One of the best You-tube channel I've ever come across! Absolutely love the content! You were explaining as if you were singing a song, how amazing and intelligent you are! May god continue to bless you abundantly in your profession 🙏💜💜
Another amazing video!
This is so cool! Thank you for this video.
Great Video! It'd be lovely to get some content about the Papez circuit and emotional processing in general!
Really love your videos! Ur videos are so inspiring and enthusiastic for the upcoming doctors in this field. Even I wanna be one of the neurosurgeon. Tysm😘
Incredibly informative. Thank you!
What reading could I do to best understand these processes of long term potentiation better? I'd like to learn how myelation happens and which factors come into long term potentiation
Another awesome video, thank you. I've worked with advanced dementia- could you do a video de-mystifying a condition that continues to affect so many of us directly/indirectly?
As always, very interesting. It would be nice to hear from you about new and innovative theories concerning memory formation and retrieval.
Great video. A thorough breakdown of fMRI and electron microscopy imaging of brain tissue would be appreciated.
Thank you so much for making these videos! I’m a (very nerdy) thirteen year old who greatly aspires to become a neurosurgeon in adulthood. Again, keep doing what you do! As someone who’s biggest goal is to become a neurosurgeon, I appreciate it! -Jed
I'm so glad you like them! Good luck to you. You can do it :)
Loved this episode, intriguing thank you 👍
Pleasure!
Memories playing very big Roll
thanks for the video 🙏
For neoplasms near the hippocampus, is there a specific neurosurgical approach used to access the mass? Furthermore, how does a neurosurgeon ensure that they won’t damage the hippocampus?
I’m currently a neuroscience premed student at university and the reason I chose neuroscience was because I wanted to learn more about the physical substrates of memory and how we learn/store memories. This semester, I finally got into a neurobiology of learning and memory class that I’ve waited for, and I’ve learned so much about memory and how researchers study it! We learned about HM in our 2nd class and read the original Scoville/Milner study for the first exam. My favorite topics so far have been how researchers are using optogenetics to find physical memory traces, vagus nerve stimulation and how it can help with exposure therapy and PTSD (my professor actually researches VNS in her lab), and how reconsolidation can be disrupted and the physical traces of memory can start to fade (meaning memories can actually be erased). Such a fascinating topic!
That sounds like so much fun but god I do not wanna have to finish Calculus based Physics II just to get to that point
Very great video.
Just a suggestion: Some illustrations(Even a short video clip from a book) would probably do wonders.
Many thanks sir. How to retrieve the memory at a specific time?
I wanted to ask you as an IMG is it worth doing a non-training route for neurosurgery and become a consultant via CEZR or i will be at a disadvantage ?
What is the link to this video
my cousin has serious epilepsy and yes he has memory problems🤔he was taking the epilepsy medicine since he was little and his IQ is half of his brother and he has both long term and short term memory issue 🤔we wrote down on a small piece of paper like "close the door lock the key" and managing everyday life but he is turning to 18 and we all little worry about his future.... anything we can try? any recommendation?
مرسی واسه توضیحات خوبتون :) 🌹
Thanks for the astonishing videos. Would you please discuss what Sleep Apnea, what it does to you the brain & the body.
For a few years now iv had trouble remembering things, I tried to study law but could not retain the information. Occasionally I do remember some things I read, but on most occasions I struggle to recall. I dont know how to move forward regarding improving my memory, iv just turned 40 years old. any advice would be appreciated. Thanks
That HM seizure story is fascinating. Loved the video
Dude I love your channel!
Brainbook Ahhhh! Thanks Alex. Catch you around the Slack group!
Other UA-camr uses strip lights and ring lights where as this guy's setup has surgery lights . What a legend
I would like to know where the data of our memories are stored? I heard it was stored in the synapses but if so where exactly? In the neurotransmitters that are located in the synaptic vesicles. Overall i want to know where is the sensory data we receive at and what form does it take chemical or electrical.
Great information in this video. Do you know if damage to short term memory would significantly decrease IQ score or is that not always the case?
Hey, Doc. I’ve had a craniotomy/craniectomy for a brain tumor (pineal ependymoma). Unfortunately, after 30+ procedures, I suffered from epilepsy, usually after undergoing a procedure (surgery), but, not always. Because of the frequency of these convulsions, I was put on anticonvulsant, (Keppra) which worked, but sapped my energy, and left me feeling really lethargic. Fortunately for me, I found another effective treatment that also helps alleviate the chronic headaches, and other pains that isn't addictive (cannabis). With that being said, what’s your opinion on the medical use of cannabis to treat pain, and epileptic seizures? Great channel by the way, liked, and subbed.
Nice video
Great !!!
Dear Brainbook team,
This is Snehal from India. Might I request you to make a video on emotions and the brain.
Like how some people turn out to be more emotional and express emotions in unwanted situations (because they couldn't control their tears) ; how brain and body react in case emotions aren't expressed adequately, etc. etc.
I (maybe) am a very sensitive person, and many of your viewers might be too. Like me, there might be many who cry at small things, and feel embarrassed for not being like the people who can react 'normally' in all situations.
So such a video would be very helpful for us to understand what exactly happens in our brains that make us over-react at petty things.
So, that we (esp. I) can stop blaming ourselves for being a crybaby.
Thank you.
And lastly,
You all neurosurgeons are great.
Cheers.😊😊
Explained beautiful, and you're channel is very good and educational. Thank you! (sorry but my not pretty english)
Thank you so much!
So interesting thank you. As simply explained as possible without over simplification. I do wonder if our brains are very similar to modern computers, but very much advanced to the extent that the various connections and functions of the synapses can influence the cognition of a memory depending on chemical markers in the blood stream such as adrenalin or cortizone from food or from visual stimuli. Our brains are organic whereas a computer's uses relatively simple digital processing which can give something approaching intelligence by sheer weight of targeted processing power. The brain however uses more associative and organic retention based on perceived importance from chemical stimuli.
Can you please make a video of how to study as a premed?
Good video! I was surprised, however, that it didn't touch on memory reception-storage-retrieval (as hinted in the title), being that memory is not one monolithic construct. It could also explain why people with STM or LTM difficulties may still have access to either of the memory's contents. Wikipedia actually has an interesting article on memory models for those who would like to learn more about psychological conceptualizations: en.wikipedia.org/wiki/Atkinson%E2%80%93Shiffrin_memory_model . There is lots of current research going on at the moment about the distinctions (or lack thereof) between STM and LTM, so it's worthwhile staying posted! :)
Doctor, a small requestrequest,pls make a video on how to form longterm memory. Dat will be very helpful sir,tq....love frm india
I would like to know how memories are retrieved from a nural science perspect.
After my brain injury I realised I had developed what I called 'holes in my memory'; it was so very shocking and awful. I can remember trying to remember a holiday I had with my son about 5 years before and it was such terribly hard work that I kept dropping it because I became too exhausted.
BAM that day I lost my short-term memory very badly: to try to make tea & toast at the same time was way too complex. Every day at the start I'd wake up and think today I will be me again, but it never happened. I found myself wandering around inside where I lived to go and get things, but couldn't keep in my memory what I went to get and sometimes made countless fruitless visits to a room but had forgotten when I got there (not a big place!); after a few days I realised I had to write them down and carry the piece of paper with me.
Because my brain injury (and other terrible injuries) were caused by NHS medics (incl anaesthetists) who lied and pretended they'd done nothing wrong and who then chose to neglect my life-threatening injuries (knowing I might die from very gouged-out throat/tongue which became very infected and unstable airway - bone/cartilage broken in front of throat and serious neck damage) I got no info or rehab: they dumped me and left me to try to deal with all of it alone - unforgivably cruel.
Long story but now 16 years later and I still have memory problems; a mix of short-term (& attention) difficulties and still some holes in my long-term memory which make me very sad; things I used to know/remember have been wiped out. I always had a very good memory - I never revised for exams because I could remember just enough to (mostly!) get through them and revision was so very dull. Also I never wanted to watch a movie a second time because even years later I could remember them very well.
Prompts of various kinds of course help me retrieve memories - we have to remember we have the memories often before we can try to go and find them, sometimes they float up without any apparent link to real life/prompting - even subliminal but what do I know?! It feels as though when I 'go to look for them' they aren't where they always were before - all jolly interesting but awful to live with; so it's far more exhausting to search around trying to find them - rather like in my messy awful filthy (I need help but 'not allowed') place trying to search for things; it's as though my organised brain systems were blasted apart and fell into different areas/places, hard to describe but I once drew a picture of how it felt: the edges of my brain had sort of disappeared and my previously strong maths/numbers skills were in these destroyed regions - still are sadly, mostly.
For short-term memory I have to really take note of what I have done and think to myself "yes, I have done X" but I too often forget, it's awful: so I then have to go look and check. Absent-mindedness on a mega scale - and no: not to do with 'getting older' as I'm too often told: BAM that day, and although a lot better than at start I still have to write loads of things down incl when I washed my hair and changed my clothes and bedding - and so on - into a calendar I print out on A4 paper every 4 weeks and carry with me always; smart phones are too heavy and hard to hold and screen too small for my injured eyes and vision so I use old-fashioned paper!
Cooking is tricky: I have to try to remember to write down times and tick them off but when too tired I forget to and mess up, it's exhausting and stressful.
My memory problems are a fluid mix of retrograde and anterograde and there is no nice line between these - all mixed up and in flux; I have lost my strong time-line I used to have and now (especially for more recent and uninteresting events) can't always place them into the right year, sometimes know time of year by what I was wearing (if I remember this) and how warm/cold it was, but not always.
People I talk to say "there is nothing wrong with your memory" because to them it can be very invisible; this denial really hurts because I struggle day in day out with so many tasks (everything is exhausting) - all of which also rely on memory, and many rely on lost skills like maths and numbers too.
I'm still waiting for my results of countless 'assessments/tests' - way too long and very cruel: imagine what I could have achieved with the right rehab and aids/help? Makes me very sad. So I really hope that everyone with a brain injury (& other injuries caused by medics) will be told the truth and get full true diagnoses fast and the right help (incl Social Care and adapted/accessible safe & affordable housing) to enable us to achieve our best possible outcomes: neglect & stress kill. Thank you.
Isn’t it interesting how the olfactory center is next to the memory center- perhaps why odors so strongly trigger memories. Cool video!
Yes, I’m currently a neuroscience pre med student and am taking a class about neurobiology of fear and anxiety. One of the things I learned is that the olfactory nerve actually has direct connections with one of the nuclei of the amygdala, which many neuroscientists believe is at the center of the limbic (emotional) system. It’s super interesting!
Hello Doc Brainbook - Would like to get your thoughts on eating specific herbs to enhance memory, cognition wellness and mind focus. Herbs I am referring to such as Ashwaganda, Gotu Kola.
Please elaborate on the role of axonal microtubules in respect to “conscience” .
Two questions:
1. Since seizures can generate brain injury but still can activate axonal sprouting is there any recent interesting research or study to read about?
2. If seizures can do this, do you think that there could be a link between epilepsy, autism spectrum and savant syndrome?
I can't look away from your eyebrows.. I hv to pay everyweek to get my eyebrows look good like yours
Eyebrows on fleek
After hearing what you said I imagine that events that cause high stimulation like the first kiss, meeting a good friend, or your first car cause that neurons to have higher plasticity (I think I used that term correctly) which then conditions them to last longer and stronger than a boring non stimulating memory like seeing a license plate and forgetting about it 10 seconds later. Kind of like muscle memory of a sport played for years. You strengthen neurons with high stimulation events to retain memories. It would be interesting to see a brains live activity scan while something traumatic happened to the patient it’s preformed on. Instead of asking about memories while viewing brain activity, cause significant ones to happen and observe. But then it’s hard because the event of having your brain observed I imagine would be a significant experience in itself causing inaccurate results lol.
Thanks for reading my thoughts lol
Would you please explain what a stoke does to the brain? Are you able to retrain other parts of the brain.
I had 3 stokes ( blood pressure went to low).
Appearance a crooked mouth when I smile.
Brain has 3 holes, one over the pituitary gland. One on each side. It looks like a butterfly.
Memory: spelling is not good.
Pronunciation of some words is very difficult. Dyslexia got worse, when speaking & writing.
My working memory is very poor, for example if i do something i forget about other. But another thing i noticed is my long term memory got better, easy to memorize and also recall. I think the reason for that is i absorb new information or recall a information without distraction as my working memory is bad. This might be the reason why it become easy to memorize and recall with poor working memory.
Maybe this has been asked many times, but do you do your own animations or do you get it from some professional illustrator?
I used to do everything in Adobe premiere myself but I get some help now. Brandon on the Brainboo team helps with thumbs and graphics and the actual editing is outsourced. Everything else is still in house
You should record In a room with less echo or use a mic cover, brilliant piece either way!
I know but then it wouldn't be an operating theatre. And I use a lav mic... it's as good as I can get :(
What do you think about the idea that sleep mediate this link between short term and long term memory?
I agree :) if you sleep poorly you can't effectively lay down new memories
I came to the comments to mention the impact of sleep. It's not just any sleep, though. Narcoleptics are notorious for having bad memory.
But does it mean in any way the additionally formed part on the neuron is perfectly equal to the actual experience / knowledge we've gained? After all, the majority of the synapses have existed in us even before we learn something new.
I just imagine how you feel being sober
But is there a way to measure our memory storage capacity?
Interesting video! I wonder why you don't say anything about sensory memory? Is this something that doesn't exist? I thought that there was another stage even before short term memory called sensory memory that stores very little information for a very short period of time before it gets transferred to the short term memory?
Thanks in advance for answering! :)
Hello! The script writer here :) I didn’t include anything too specific just because memory is such a colossal subject and we aim for a wide audience here at Brainbook. We hope anyone - general public, doctors, students etc - can enjoy our content :).
@@misscamillacakes Oh yeah alright I understand that! thanks for replying :)
I am a simple guy i see new video by Brainbook i click
Haha thank you
I don't understand why people believe that we can't remember anything from before 3 years of age. I have several distinct memories from when I was 2.
I 'M AN ANESTHESIC FROM ALGERIA.
CHEEEEERRSSSS DR ALEX.
When you speak of “short bursts of high frequency, is that the equivalent of K-complexes during sleep?
Question: at ua-cam.com/video/TXfVRs47EdM/v-deo.html, what is meant by the phrase "which areas of the brain are more accurate..."?
Two things, Is instinct a memory, do babies really dream in utero, if so what do they dream about.
THANKS MY COLLEAGUE FROM ALGERIA.
Lol that's ok but in not from Algeria
@@Brainbook brainbook is algerian confirmed
Lol
❤❤❤❤❤
I ended this video more confused then I started.. think I need to stick to Jerry springer and south park videos 😅
I like neurosurgery but I love plastics more
What about involuntary memory recalling of veeeeery random , vereeeeery old moments that is not significant or relevant 🤔 things I am surprised my brain is even store
I'd like to know why I keep getting denied my goals jn life. With other smart and ambitious people!
...great quality video btw))

@@DrumHeadV thanks a lot !
@Haus hahahah 😂😂😂
Thanks doctor! Can you please post your thoughts on Elon Musk's neuralink?
Constructive criticism: Get rid of those cuts where you're changing the zoom level on each new paragraph in your script. It's way too frequent and pretty irritating. I almost left the video because of that. Constant quick cuts editing style shouldn't be so repetitive between a couple states (ex: 2 or 3 zoom levels in this video).
The other bigger issue about this video is that - despite it's title - it does not discuss how memory retrieval works... This was more about the properties of memory, a case study of memory problems, and some speculation. The title of this video is "how does memory retrieval work in the brain?". In no part of this video did you explain what happens when a memory is retrieved nor did you explain how the brain retrieves a memory. The closest you got to explaining it is when you said neuron synapses that are used heavily are more likely to store that memory. I was looking for info on what is actually happening when I (the brain) is trying to recall a memory. What is happening when I'm searching for a memory (aka retrieving a memory)? How does the brain search for memories? How does the brain store memories and how does it catalog them? When I'm actively trying to remember something but it's taking me several seconds to actually remember it, what is the brain doing to search for that memory during all of that time? And how does it know it found the right memory? None of these questions or any related topics pertaining to retrieving memories are touched on despite the title of the video implying that's the subject matter topic.
Why can't we think of a new color?
I think we know all of them...

(On Monday May 1, 2023). On the matter of Neurocognition and Memory (Neuroanatomy and Physiology therein) by Brainbook: 1) Hippocampus and Parahippocampal Areas are so vastly interlinked via Canonical Pathways and Not so Recognizable Links (fMRI has limited Diagnositc Application but Infinite Research Capacity Therein). I rather say Ablation of Certain Cortical Area yield these Effects in this Particular Person or Species. It is a Problem in itself. 2) Certain Pathological Features or Traumatic Injuries to Temporal Lobe, as an Example, has yield remarkable Geniuses in some cases but Nil in others. Or the Angular Gyrus. The Insula. Etecetera. MDx, es gut ist aber es soll hochest sein gewesen. Heil
Zoom out in these videos -
back that camera up a bit
Yeh I thought so too. Not sure what happened there
Our neurosurgeon said brain is a stupid organ:)
the music is so distracting..why on earth did you add it?
Do you think there will ever be a cure for alzheimers?
If in between saving lives and educating people, you could wipe your glasses, it would really go a long way. Very interesting and informative video though, thanks.
Haha fair point. I dont notice these things!
human brain is always ready to go bonkers, it's v fragile

Nope
interesting information, but why in the CRAP, do you have that stupid music playing in the background???
Your video is very boring. No charts, no diagram, no examples.
