- Discover the phenomenon known as asymmetrical sleep, where parts of an animal's brain are asleep while other areas remain active.
--
Many animals need sleep. But all of the threats and demands animals face don’t just go away when it’s time to doze. That’s why a range of birds, mammals, and even humans experience some degree of asymmetrical sleep, where parts of the brain are asleep and other areas are more active. So, how does it work? Masako Tamaki explores how animals' brains remain vigilant even at their most vulnerable.

@@arjunkabule5707 looks suspiciously like the young generation obsessed with status symbols akin to tribal markings, having yet to come to terms with their identity while struggling desperately to elevate above the legacy of their progenitors... or it could be the latest tik tok thing that will be gone in ten minutes. pay it no further mind.
I guess this is what happens when you're a deep sleeper, but when you know you have to wake up early for something very very important the next morning, you will still wake up on your own several times before the alarm starts ringing, and be ready to get up at any second
Huh I thought that was just me lol
that happens because your brain has a timer and it knows when to wake up (based on what time you woke up the past days)
it was difficult. I was about to go to sleep (watching yt with earphones) when I suddenly collapsed. i heard low frequency booms in my head and i can't move my hands correctly (its like my sensitivity settings is maxed, fr). it's difficult to talk, i was SUPER dizzy. I tried moving both my hands and they're moving like 🔁🔁🔁 😭😭
yeah...

Can you please make a video on maladaptive daydreaming, or daydreaming in general.
Bro maladaptive wht is this?
@@nandaverma1647 its not officially a disorder ,but it has been found that a few people tend to daydream abnormally lot compared to others may it be when introduced to a problematic situation(even exam or school ) or just generally , it's not confirmed that it's uncontrollable but as someone with this condition (self diagnosed ) I would say we might have control upto an extent but the situation can really take over . There's a lot more to it , It would be really helpful for me if Ted ed made a vid about it .
As someone who constantly drift focus from conversations to own thoughts and fantasies, I can relate to you. It's really inconvenient especially when there are extremely important things, but my brain just refuses to listen 😢
@Fishbone do you tend to walk around a lot while dreaming?
@@fishbone-thestoryteller like walking aggressively and hand moments or lip moments according to the dream .

Thanks Ted ed for the heart and thanks Ilyana for congratulations!
Can we appreciate the staggeringly amazing job the animators did on this one?
Like who can even imagine a walnut falling from the tree symbolising the brain!?
Somebody call Robert Langdon
Yeh have seen many of these "can we appreciate" comments on Ted. Though the point stands and they do a very good job with their animations
@HIMANI PANT Yes but would you have the presence of mind to think of a guy under a tree when you're thinking about sleep?
Most people know that a walnut looks like a brain. Just like most people would see the connection of the falling nut to Newton.... But yeah. Sure, whatever impress I guess...
@HIMANI PANT Agree

Can you be awake and asleep at the same time?
Short Answer: *Sleep paralysis*
Long Answer: *Ｓｌｅｅｐ ｐａｒａｌｙｓｉｓ＊
Even those birds need to open one eye but during sleep paralysis i can see clearly with both my eyes closed
I would wager that atleast 80% of the people who liked this comment have experienced sleep paralysis at some point in their lives.
May anyone explain me wht is sleep paralysis
@@nandaverma1647 We can help you out! Here's our video: bit.ly/TEDEdSleepParalysis
You can wake up from a sleep paralysis by holding your breath. Your brain realises that something's going on and it instantly awakes all your parts. You welcome.
I'm both asleep and awake during classes, so yeah we do asymmetric sleeping
Especially, when your science teacher dont know what he saying
@@Heheheheheehhehe 😂😂
That's true
literally me in the mornings hitting snooze

This video is right on so many levels.
After having two in-home invasions and always having the fear of my daughter getting injured, I found that I was sleeping with one ear open, so to speak, since 1999.
Now that my daughter is away at college and I'm semi-retired....
I'm now sleeping a lot.
I honestly feel like I'm making up for lost time.
Damn at that point I would just buy a really nice security system
Unfort. you cannot make up for lost sleep. I am glad to hear you are safe and sleeping better tho :)
Maybe that's also why my sleep has been shittey for nearly a decade and a half, but the person who was most affected by the invasions we've had had passed away two years ago.
It's why I've taken sleep aids on an almost regular basis.
TED-Ed: humans are more vigilante when asleep in new environments
Me, a deep sleeper: ok but like that doesn't change the fact that you can still kill me in my sleep
No 'e'! Vigilant and vigilante are two separate things.

@@zijing9548 exit light, enter night
I've always considered myself a light sleeper and easy to wake. One thing I always found strange was how often I would wake up a few minutes before getting woken up. About 2 years ago, I got woken up by a noise outside, but I still managed to wake up about a minute before that. That's when a realization hit me. I think part of my brain is always awake, processing sounds, but it's short term, so it's all forgotten. When I get startled awake, those memories are still there, and they get processed and it feels like I've been awake for a few minutes because I have a few minutes of memories being processed.
I think that counts as being awake and asleep at the same time.
Same, I'm a light sleeper. I also experience waking up a few minutes or sometimes, an hour before my alarm starts ringing. Any slightest sound, light or touch can really woke me up that's why I wanted to sleep in a very peaceful room so my sleep won't be disturbed.
That's pretty cool
sleep paralysis?
I learned more about animals sleeping than humans… bit of a let down, but very informative!
Haha same. The info about one open eye was completely new to me
This is probably the explanation behind my experience before. Years ago, I spent most of my lunch breaks taking naps. Nothing unusual, right? However, I noticed something weird. I was asleep but I could still hear and even follow the conversations around me. I knew I was asleep because I was dreaming at the same time. Like I would suddenly wake up and say “whoah! I just had a dream about this, etc”… people would give me this look that implied “of course you had a dream because you were asleep”. But I couldn’t explain to them that I was asleep and even dreaming but how come I know what they were talking about while I was sleeping. This video finally gave me the explanation that I’ve been looking for. For years I thought I was just hallucinating. 😉

Is someone sleeping or wake?

Another way humans can sleep with one part of their brain more active than the rest is in lucid dreaming, during which they are aware of the fact that they are dreaming and can actively interact with its elements
Where I live, we call being half awake and asleep "fishing" or 钓鱼. This is due to the fact that your head bops up and down trying to stay awake but your too tired for Calculus at 8.00am in the morning
祝你年年有鱼🐟hhhhh
I like that. Doing math early in the morning is always horrible.
fascinating. this explains why I find it easier to go back to sleep when I get out of bed with only one eye open. I didn't realize that to so many other animals did this too.
i hate when i'm almost falling in deep sleep, then something comes into my mind and i go "no, noooo! don't think about it, don't think about real life!" and i think about it and TADA! Fully awake.
This is me dude!
Oh my god you are so funny!
I lived 50 yrs. with little sleep. I wondered why I never dreamed. I had other problems too and at one point I couldn't walk.
I went to a concert in Canada and didn't sleep the whole time. And when I got back, I went straight to work. 56 hrs. With no sleep.
Then I was diagnosed with Fybromyalgia and my life began at that point. With medication, I have finally begun to dream and feel rested. I'm not in constant pain for the first time and life is more bearable. It's amazing what sleep can do.
I’m in love with this video, and Ted Ed. What an amazing subject
It’s always something new to learn from this channel and it is always enjoyable. ♥️
Well this sure was a very nice Ted-Ed as always.
Also I wish y'all a good restful day.
TED-ED is the best channel... it clarifies so many doubts of mine from childhood
Such an incredible video.
Very informative and insightful.
Haven’t watched the video yet but no my brain never shuts off what else keeps me awake at night?
Same here
Bro just close your eyes haha
Close your eyes and restrain your thoughts to things you're looking forward to.
Just read books
Close your eyes through the night and never open it, no matter what you hear or feel beside you. Assert dominance!
My brain did this after I had a baby. It wouldn't let me fall fully asleep and I was always in a state of high alert. If baby cried or whimpered, or even made slight movement while i was holding her I would snap wide awake again. It didn't feel like I fell into deep sleep ever and if I slept I woke up every 30 min to one hour. It was pure agony and I hated it, but it was the biological way my motherly instincts kept me awake to take care of my newborn's needs
I don’t know when I last laughed so hard. You folks are so funny ! Thanks so much, I needed that :)
thank you , this really clarified this problem i was having recently to a degree
Its past midnight here in Malaysia. I should be sleeping but I rather learn about being both awake & asleep
Congratulations you are a Scientist now
Hello from the U.S. I’m not sleeping either…. Or maybe I’m half asleep.
I clearly remember one night many years ago. I was in my bed, neither awake nor sleeping. I was thinking about this very tall animal with long legs and a long neck. I also knew, that in several European languages it was called almost the same, but I didn't remember the word giraffe (English), giraf (Danish) or sjiraff (Norwegian). However, I clearly remembered the word twiga (swahili). I was conceived in East Africa by North European parents, who returned home a couple of months before I was born. I have never been in East Africa since I was born, and I don't speak or understand swahili, only very few words, I picked up during my childhood.
Productivity type: In my work career I traveled from home frequently. During this time I had an unbreakable habit of always staying in Marriott properties. I learned to love the familiar feel and vibe and after a long journey. I cherished hearing the same scripted words from different clerks using the same script as before. Same fixtures, furnishing, bedding, towels, soap. I slept better this way and it boosted my performance and energy.
I really like the quotes at the beginning of every video
Yes, sometimes when I'm super sleepy i close my eyes and see dream like images while being able to move and control them, a sudo-sleep if you will
When I was a child sleeping & dreaming in my room my mom would barge in to wake me for school. At times she would just start talking to me while I was still asleep. There was a rare moment where I was dreaming and I was hearing her voice talking to me only it was being spoken through a character from the dream I was in. What’s crazy is that I actually talked back to the character in the dream and (according to my mother) i was actually speaking the words in real life , I was laying there in my bed asleep having a conversation with my mother while I was dreaming!
Only once????
@@pouringyourheartout9464
Why Do you sound ✴DESPERATE〽
The best memory reinforcement is to take images of every thing. All my travels, special occasions & family pix. I have about 1.5 terabytes of photos, videos & occasions stored in three copies on independent hard drives to protect their loss. Often I slip into clicking on photos & videos to enjoy immensely memories that I had almost forgotten. Looking at the thousands of photos & video clips I live my life again with great enjoyment as all the memories dimmed by time come back clearly to match the memories in my mind. I have done so many things, traveled to so many places and met just wonderful, educated, brilliant people. My photos & videos allow me to meet & befriend them again even though many of them have long passed.
This is the best channel i have ever found on UA-cam tbh, forget about tiktok

I create elaborate stories in my head and usually continue them at night. Normally it’s the same story with a little variation. There have been times when my brain has worked so hard on keeping the story going that I don’t fall asleep properly and it feels like I was awake half the night so focused even though my brain tends to wander after I fall asleep.
I hate when it happens because then I wake in the night and night feels very long and tiresome.
Thats a great idea. Will try!
MaaaaShaaAllah for your enticing research and alhamdulilah for mindblowing body.
Nice information Thanks.
it was literally brain in a nutshell.
4:46 So, While your hotel room is obviously not trying to eat you XD there's always a funny part in these TED-Ed videos keep it up guys.
I used to consciously keep one eye partially open while sleeping during Scouts tours. Helped me discourage kids plotting to prank me on several occasions - usually a simple "I hear you" is enough. Then it doesn't take much time to fall back asleep.
This video choosed to be on my homepage when I'm dealing with this weird thing currently. Whenever I wake up in the early morning, i think to myself, did i even sleep?? Like i see the coming morning with open eyes! But then i realize i dreamt too while feeling somewhat fresh and in a dilemma at the same time!
Haha I always though of walnut as a brain and when I looked it up it indeed is good for the brain. I felt so satisfied when they animated it like that. Thanks TedEd.
I would love to see a video about lucid dreaming to that specific topic. How does the brain work when you're lucid dreaming? Is it still as restful as normal sleep?
Yes pls!
im scared of the ocean and honestly really appreciate the simple and cute art beginning if video
Ted Ed making me smarter. I appreciate that. Thank you teddy!
Please make a video on Mahabharata 🙏🙏...It's really inspiring✨

Actually used to experience this half asleep, half awake issue a lot. I had a sleep study done and was surprised to hear that I slept fine since I was aware of the room, sounds and being awake all night. Always wondered how I could be asleep and awake at the same time.
Could this explain how we're sometimes able to fall asleep on lectures and still hear everything that is being said? 🤔

I keep continuing my dreams after I wake up for a few seconds or maybe I’m just hallucinating
Really? that's weird and cool
Same. Or sometimes I have a dream one day and weeks to months later, the same dream continues. It's weird
I can still be dreaming and aware of my surroundings and "awake" at the same time sometimes. Or wake up go do stuff and then come back for a nap an the same dream continues where it left of. Sucks when it was a nightmare though 😅
Watching this around 1AM and I'm like 'heck yeah'
I live on the streets and I'm used to sleeping with one eye open, luckily I have a good doggo to help delegate the roles of keeping an eye out for our saftey
i just wish i can study and sleep at the same time
I always tried to “half-sleep” like dolphins in grade four

I am amazed you keep doing unique animations one video after another, keeping it fresh. Props to that!
This explains why sometimes I feel like I have been awake the whole night and remember events throughout the night but still feel like I had a good sleep or am well-rested.
No.
This never happened to me, you might be talking about lucid dreaming
I’m listening.
I think I may have done this before but I can't actually tell, but the fact that brain activity from left and right portions of the brain can differ means it may be possible so maybe I did do it. Either way thanks for informing me that it is more plausible than I thought.
Well, at school you definitely can...
During exams seasons and when studying I get to sleep half minded where I am sleeping but I am conscious as well. And it irritates me
Need a video on humans' sleep types. Like when do we have a deep sleep, when a sleep that makes us feel energetic/lethargic, and when a sleep with recurring dreams because I have had all of these.
this is so interesting
Awesome vid thx teded
I wanted to see if anyone has similar half-asleep experiences to mine in the comments, but everyone just reuses the same joke as how they are half-asleep during boring activities 😐
Sometimes when I am very tired and try to fall asleep, within minutes I enter a state of "sleepy-wakefulness" where I see made-up images and events that I did not consciously brought up, very reminiscent of dreams. The difference with actual dreaming is that I am still somewhat conscious at the time and I am able to properly snap out of it if I so want to.
Does anyone else recall having a similar experience?
I agree, I prefer thought provoking commentary and original wit than the overused responses. Regarding your question: no it's not just you 😁. If you want, have fun with it, see if you can direct it or dig deep into the mental imagery and sensations in that state.
Very tired = sleep deprived or regularly tired?
@@TheOmegaAlfa Now that you mention it, I am probably on the sleep deprived side. Is that related?
@@Sol-Amar Huh, curious. Is there a name for this condition? I remember searching for it using various queries and wordings, but nothing relevant came up. Everything that pops up is about lucid dreaming or sleep paralysis, which are different, since the phenomenon I am describing happens before actual sleep occurs.
@@Leonhart_93 Yeah I wouldn't classify it as neither sleep paralysis nor lucid dreaming. I think the term hypnagogia is appropriate. You can read about it using the following link below: en.m.wikipedia.org/wiki/Hypnagogia
(Or just search hypnagogia in a search engine.) Good luck!
I feel like it could be worth having series for people that are familiar with psychology where they can get into more technical terms and depth instead of it being quite comprehensive

I'm pretty sure my sleep is unihemispherical. There are often times I know what time it is before I wake up. And other times were I go to bed after having a long failure of a day, have no dreams, and yet when I wake up I have several solutions to yesterday's problems. It seems that some half of my brain is routinely pulling all nighters.
This is actually so cool ngl
Great
