- Explore the science behind how your body and brain process different sensations like touch, pain, temperature, and spatial awareness.
--
We don’t often think of touch as being a vital part of movement, but touch is one part of a network that oversees all the sensations arising from the surface and interior of our bodies. Touch, pain, temperature, and our spatial awareness are regulated by this system. So, how exactly do our brains process these sensations? And what happens when something goes wrong? Antonio Cataldo investigates.

It's crazy how many things we take for granted until we lose them.
Should we not take it for granted ?
Goofy ahh comment
@@SobaYatai goofy is a Disney character
@@Looking_at_the_viewer Anything shouldn't be taken as granted.
@@Barnil_JN I must be *_crazy_* then
As someone who experienced nerve damage after a broken ankle which caused numbness, I can say it’s really scary not being able to feel ANYTHING in my foot.
What is walking like? Can you feel the pressure of the ground and your leg, or is it like walking on a stilt the whole time?
@@PramkLuna well seeing how their ankle was broken, I dont think they were doing that much walking
I have idiopathic neuropathy and have lost sense of touch on part of my arm and wrist. Also the back of my foot. It sucks
I’ve had severe migraine before to the point that I needed to get my brain scanned because it resembled a stroke. One half of my body went numb and I had aphasia which means I couldn’t speak properly. It is rlly freaky to lose feeling. I can move my body but I have to look at it to confirm movement because I really couldn’t feel it move. And walking was a nightmare. People don’t know how much we depend on our sense of touch to walk in a balanced way. Depending on eyesight alone is really tough and downright impossible as someone with a migraine whose eyesight was also affected. I was not aware of how we walk because we just usually depend on our sense of touch.
It is quite common to experience numbness in feet when sitting uncomfortably for a long time.
I think everyone has had this experience of not knowing when the feet touches the ground and not knowing how much force to apply to stand erect (when experiencing numbness).
The human body is a delicate and extremely sophisticated complex machine. Its mind blowing how much I learn from TED-ED!!
Is it a machine or an organism or a organisation of cellular machines?
@@Bibibosh love what u wrote
what if it was not a machine, but somethin else than just a comon word that people overuse to describe anything ever even maybe??
#rioting for the stopping of recycling organic 'machines'
@@awecwec3720 thanks! the thought just came naturally.
@@awecwec3720 even a computer has cells.. everything has cells. matter even has crystal "cells" like thats crystal cells
Fascinating. Can you imagine not knowing where your limbs were without actually *seeing* where they were?
I can’t
@@K__kelly same
Losing touch must be terrifying. Like looking at the world as a ghost
You cannot balance well either or know how to move your body and walk around.
If not for this era of science,
I would have died without learning so much about this beautiful system we have.........
other "eras" of "science" have much more to teach than a pseudo-poetic obvious "woke-realisation" 6min wonder-catchy video, u just dont know about it, the following sentence u wrote is quiet the ironic sentence
You are right, we are very lucky to live in an era where all this amazing information is available to everyone.
@@cinemartin3530 tru
yes
"Even if it can be tough to put your finger on."
Omg the touchscreen visual at the end was so small but genius!
I had a wisdom tooth removed and the surgent hit a nerve. This caused a part of my lower lip to lose its ability to feel pain, pressure, touch, and temperature. I can still move it like normal.
After over a year, I gain some feeling of pain and pressure, but it is very faint.
Can you sue?
Can u describe what that is like
i will literally remove my wisdom tooth tomorrow 😭
@@Bibibosh No, you sign a waiver before surgery understanding the risks.
@@superduperkimberly7831 Like when your arm falls asleep and it's just there. After a year or so, I only noticed the numb feeling when I think about it.
I like the drawing style. Animators, as always, did their best! 💜
So cool. By the way, I have difficulty communicating because I had a stroke in Broca’s area, the part of the brain that controls speech. 2/8/2021 but I lived again. (My wife helped me compose this.)
This is good news I'm happy you've been doing well after all 🙏
I swear, this channel is helping me to slowly rebuild my life, while learning new facts every day
I think I heard about that guy on an episode on Radio Lab. Fascinating how the body can adapt and compensate for loss of certain functions. Not that it didn't take amazing effort and willpower to overcome!
yeah like you just straight up stop seeing and your body is like "oh well, start feelin around and see if you can hear anything"
I’ve always loved TED’s quality of content. It really worth your time
I lost the sense of touch to my upper back during a surgery and it’s so weird having no idea if I’m actually using muscles in that area or not. Can’t even tell if there’s a cut, bruise, or just any of it
I never knew there was a condition such as touch starvation.
No wonder being an only child with few friends I often crave human touch or social connections after being alone for some time or when im anxious
try adopting or rescuing animals
That animation was beautiful and portrayed the message really well
Thank you for his video !! this will be very useful to teach people about losing the sense of touch.
Sometimes, I asked my friends which sense would they pick if they have to sacrifice one, and I'm often surprised that some people choices the sense of touch as an easy answer for this question.
A very good video of TEDx. It’s truly fascinating to see how complex and delicate our bodies are!
Once, I've slept on my right arm for so long that I couldn't feel it for more than 2 minutes!
It was the scariest sensation ever, I knew I was moving my arm, but my brain couldn't understand what was happening and how I was doing that 😅. I don't really know how to explain, but I thought I was going to lose it, lol!
Excellent video. Sensation is a key factor in learning process.
Wow...This dude, I didn't even know that it's so important for us to feel the body parts in space. Nevertheless, the human body is capable of much and can be considered a real treasure of nature. Seriously, I am surprised by such a complex and thought out to the smallest detail system. Even if something breaks, the body always finds a way out. Videos like this make me appreciate my body even more.😏
And to think that literally everything alive that moves has the exact same thing/something like it.
It's extremely fascinating how such a creature like human who is only created because random chance based reactions and has such complex and highly coordinated system.
"Random" in nature doesn't exist, just systems that are too complex for our brains to keep track of.
@@OMalleyTheMaggot I do know about determinism. But when i said random, i meant in the sense of no sentient intelligent creature like human being in control of the occurence
Such a big coincidence...
Because we evolved so? Bro thinks we just came out of nowhere
We live in a simulation, its not a surprise.
“You’re out of touch! I’m out of time!” -Hall & Oates.
Mind boggling and eye opening!
Body and mind connection is fascinating. I'm a SA survivor and it's very interesting how trauma is stored in the body. I sometimes disassociate from my body, which is what I did to mentally survive the SA. Problem is it still happens now when I have flashbacks or am triggered by things. The book The Body Keeps the Score by expert Bessel van der Kolk discusses how yoga can retrain the brain and body to understand that it is safe now, to untrap it from the trauma of the past.
It’s very interesting to know that the body brain connection can be trained like this and can change so dramatically. I hope you are doing well :)
Hope you're doing okay! Thanks so much for sharing and so glad you're utilizing the power of yoga
the animation is soo good. can't stop watching and at the same time learning so much from it
Touch has memory
I confirm it I still remember the projectile hit of utensils by my mother
Broo
One of the best animation and sound effects combinations among all videos!
I had a mild stroke 9 years ago and for a couple of weeks I lost all feeling on the left side of my body. I could still move and walk but like the video describes, I had to watch my left hand to know what it was doing. If I picked something up, I didn't know how tightly I was gripping it so if I stopped watching it, I would drop things. Luckily my feeling came back. A man in my stroke recovery group never got his feeling back on one side and he accidentally burned his 'unfeeling' hand really badly on a grill. he didn't feel it but eventually noticed the smell of his burning hair and looked down.
Beautiful animation and an informative, interesting video once again!
ted ed always coming in clutch in the middle of the night
Hahah nice, its afternoon here.
10:12 am for me, it's a cloudy day
@ ⭐️What's App me 𝟙 𝟡𝟠𝟞 𝟛𝟛𝟞‑𝟘𝟝𝟡𝟟 you need to die as quickly as possible while dying as slowly as you can
Absolutely excellent!
It is sad that we taken for granted about this.
I guess we should also celebrate nervous system awareness day
I would Not want to lose a sense of touch. Yet another thing to add to the list of horrifying things.
This woke me up to some issues and challenges since brain injury thankyou
Beautiful animation, great information
The body can so terrifyingly fascinating sometimes.
Wow, this was super informative! I had never heard of something like this happening before.
@@drakebalzer3950 Oops yeah!
I cried, it's so beautiful ✨
Thank you!
I like how they added "touch starvation" in this video.
The information gathered here are so sensational
More disturbing is that our nervous system can be turned against us, like my mom who had cancer in her spine affecting her spinal nerves that create unbearable pain signals in her legs. She passed away from her cancer.
Hope she is resting in peace now. Cases like your mother's remind us of how blessed we are.
@@user-tr9ox6nb3i thank you for your kind words. take care and keep well yourself.
'Being deprived of social touch can cause a condition known as touch starvation.'
This seems kinda familiar and now I'm more depressed.
It a all good bro keep working on yourself and you'll get out of this
adopt a cat or dog
@@petsgamesandrobots438 pets are not allowed in hostel. Besides I'm afraid of dogs. And cats don't like me.
@@aprilrahee Go for plants instead then.
"Am I so out of touch?
No it's the children who are wrong"
As always 10/10.
You got me with the segue to touch starving. I never expected to guffaw such a serious topic
Interesting consideration! I will propose the topic on my channel.
Love the music associated with the video very suitable
If I lost my sense of touch, I'm not sure how I would feel.
I see what you did there
I thought it would be a sense of danger, coz people these days seem to lack this.
But in all seriousness, this is something I thought was just some comic book fiction. It's absolutely crazy.
This one time I made my foot really numb, but I didn’t notice it so I started walking. It was compnfusing *and* scary. It went back to normal in a bit though, so that’s nice.
Simply the best ♥️👏♥️👏
i believe the real breakthrough in "metaverse" must come from touch than vision
what a great visual and sound here, by the way
Because Knowledge is Power ❤
Quality like this feels undeserved.
thank god, Ted Ed's uploading new videos almost everyday!
Love this video! Great stuff! Interesting material
This is. Amazing 😁🤎😁
It's like I have ESPN or something!
👁👄👁
In all seriousness, there was something different about the tone about this video. I can't put my finger on it. It was gentle and serious but also informative. Thank you as always, Ted-Ed!
Ted Ed should mentioned their soundtracks used in description and post it separately on a another place, You guys makes a lot of Good Music to listen!!!
Love the animation in this video though ❤
Losing touch is a horrible thing!
Is it just me, or is that girl on 1:51 looks like Toph from the Last AirBender.? Good subtle detail there Ted-Ed. As always, very educational and intertaining video.
"Just tell me what I want to know, no need for this to get bloody!"
So touch is my secret sixth sense! 🤯🤯🤯
No
Its proprioception
This is heart breaking and anxiety inducing. Id hate to experience this.
The whole 5 senses thing is a myth, we have many senses: time, temperature, hunger, location of body parts in relation to each other, balance, etc.
Temperature is touch, time is a mental calculation, hunger sensation is caused by your stomach being empty (which is a touch sensation).
Balance and location are the 6th sense described in this video
Proprioception is our sixth sense responsible for balance and location
can you talk about microneedling and its side effects? 😊
Actually the pressure sensing problem was a big thing with the first generation of “nervous”prosthetics which uses sensors attached to your nerves to a CPU and wires within the arm to control and relay touch and movement like a real arm would
I sometimes can see/hear a fly buzzing around me. I can catch the fly more time out of 10 then I miss it. But if I try to catch the fly I alway miss. It only happens when I don't try to catch it. Like the spur of the moment.
I did experience not feeling anything after getting anesthesia, i felt scared but after some hours it gave me laugh
Truly amazing. God is so thoughtful. His intelligence is impressive 👏🏾👏🏾👏🏾👏🏾
Are you guys ever going to talk about Bulgarian history and moments in time and historical figures.
This is fascinating, there is so much to the subconscious brain.
What animation software was used in creating this animated video?
الحمد لله على كل شيء
What I’m getting is that the song Paralyzed is about this guy. “Where are my feelings? I no longer feel things, I know I should. I’m paralyzed”
this so sad
One of my biggest fears is not being able to feel pain
Why's that?
@@msjkramey because, if you dont feel pain then u wont know whats dangerous or not and you could get heavily injured or worse.
@@tribaounidadedonstania I was wondering if there was a more personal reason
@@msjkramey well..here's something philosophical you were expecting.. you can never be happy unless you know what sadness is.. so you'll never be joyful unless you've known what pain is
Real world : All senses including touch
Digital world: Sight and Hearing
Food: Smell and taste
Touch is the only sense that makes us realize that we live in a physical world. If not for it, you would have no idea of when you are dreaming and when you are awake- unless you are eating something.
All of our senses are just refined forms of touch.
I don't understand few weeks ago I was thinking about it and Ted posted it, talk about Deja vu 😳
Nice video! But why is the thumbnail „the secret sixth sense“, when touch is literally one of our five senses?🤔
5:37 smart :)
It's like playing a game with the TV turned off. You're pushing the joystick, your character is moving, but you don't know by how much and where they are.
That was very successful
One time I was walking in my house and I had this weird thought “how am I walking without thinking?” Then I almost tripped
This is slowly happening to me in my entire body. Impaired sense of smell and my hearing is not great for my age either.
I am 30, not old
wow
This is what I have been wondering since I was 5.
I would cry on the spot
How does this effect the body as you age and the skin 'deforms' more?
After 10 years i will come here to watch this video again.
Why?
Wow
Reduced social touch can impact our immune system? Wow, if only that had a recent applicable policy application.
one time i fell asleep on my arm for probably the whole night and when i woke up it was numb and i couldnt see it either in the dark. i went to rub my eyes and accidentally slapped myself in the face super hard
How perfect our body is...
2:42 why would that bee do that?
sometimes when i wake up my limbs are numb and i can't move them, or some other times i can move them but i feel immense pain if i do
is this related?
