You’re probably familiar with that flash of recognition that happens when you see a person and suddenly realize it is someone you know, but neuroscientists have been trying to understand exactly how our brains do this for years.

I would love to see what these tests would show for my specific type of face blindness. I cannot remember any faces unless I'm looking at them (including my own) but once I'm looking at someone, I recognize them. To see what the scans would show when I'm trying to remember a face compared to when I'm looking at one would be fascinating.

Grandma neurons sound like they would be clustered around a fireplace, knitting, or in a kitchen baking cookies for little neurons.

As a face blind person, I am honestly surprised and intrigued by this phenomenon
@@r.m2192 He said face blind dummy 😑
@@basil2270 I misread it, why do you feel the need to be like this
@@r.m2192 Ehh what ?🙄
Face blind? Does than mean all humans look like mannequins to you?
@@adnan7698 no, it is a bit of a misnomer, we can see faces, we just can’t remember them later as easily as others!
Like the general idea that Serotonin makes you happy, having a Grandmother Neuron is an oversimplification, but it's still very useful for the general public to be able to comprehend how our minds work.
Interesting.
Reminds me of category theory in mathematics:
You create a meaningful map between objects of a category and create an "analogy" (a functor) between categories to carry over the particular mappings in a new context.
Fundamental is transitivity of mappings:
If there is a map from object A to B (noted as ->), i.e. A -> B -> C then there is a map A -> C.
After sufficient association you create a new link, a new "map" from sensory input to a particular face.
I wonder...
A grandmother cluster!
I just saw a comment where they just said "no" with no context and I shat bricks
I just saw a comment where they just said “I just saw a comment where they just said “no” with no context and I shat bricks” and I shat buildings

It was my very good comment that you laughed at
I found it lololol
I am faceblind… I spend my time looking at gait, hair, height, body type, fashion taste… and even using things like people’s natural scent and voice to try and figure out who people are.
It’s a pain, but I’ve never known any different, and apparently it makes me more perceptive of specific things.
Faces are largely useless for me. I am also autistic and don’t find facial expressions useful either. Body language is much easier to understand.
I can’t even remember my own face in the mirror.
I am curious, does this carry over into pets/animals?
Same! But considering how many specifics that go into facial recognition it’s no surprise that some people would be worse at it. I usually describe my face blindness as stepping into a room full of impressionistic paintings of the same flower. Some may use different colours which makes it easy to remember it, some may have a different angle, or somehow anomalous. But so many paintings from the same angle with the same colours take a lot of effort to memorise. So you start looking for a distinct detail, and the more you see the painting the more familiar it becomes. Just like any other object.
So @Chas Abetz: no it doesn’t carry over into animals, cause animals don’t have human faces so everyone is “face blind” when it comes to animals. Everyone has to look at animals and memorise patterns and get familiar at the same slow pace that face blind people also have with humans.
@@Hejswejs that’s a good way to explain it!
I say it’s a lot like watching Anime. Up close I can see all the individual details, but when I “zoom out” I just see eyes, nose, mouth.
The details beyond colours and major shapes are pretty much the same.
@@princessemerald849 it plays a small part, like an arm or leg might to someone else?
Mostly I find personality attractive, but that might be more to do with my personality, I don’t know. I’ve never been able to see faces the same way others do.
@mrE365 Researchers think about 2% of people are face blind enough that it affects their daily life.
Huh, so I have a Hank Green neuron. Sweet.
Well, a Hank Green neural clique at least :)
@@IceMetalPunk even better.
I think it would be linked to locations as well like you immediately recognize coworkers at work and would take a bit longer if you see them at a different location.
Sometimes seeing coworkers out of uniform is like remembering seeing my bearded, mustachio'd father clean-shaved for the first time... it's uncanny how much they look like someone you know except not quite -- oh, wait, they *are* someone you know -- dude! you don't look yourself at all! put your uniform/facial hair back on right this minute!
So your brain keeps a hashmap of faces that allows it to say "yep, that exists in the library somewhere, go search for it"
To be fair, the point of a hashmap is that once you've confirmed the hash is in the map, you've already found what it maps to :D
Ehh, more or less. Depends on its propensity for collisions and false positives, which seems to be pretty high since it's faster to say "I know that face" than to actually put a name to it.
I can recognize someone by the way they walk long before I can make out their face.
It's fascinating to me that you can do this, since I have extreme difficulty processing (understanding, recalling and translating or mirroring to my own body) any movement. Static visuals, I am decent at remembering, but I cannot watch even a simple dance move and understand what is happening to copy it. I have to repeat it multiple times in slow motion, focusing on one part (what the one arm is doing, then the other, then each leg) at a time, and try to match the movement facing the same direction as the originator, and eventually kinda understand the whole. But even then, I can't mentally imagine it (I have no mind's eye).
.
I have very good recall for sounds, though, music, human voices or instrumental, animal sounds, random misc. sounds. Do you do well or poorly in this area?
.
I am terribly curious about how our neurological profiles differ, yours and mine, that allows your brain to pick up on movement above static visuals (faces) to the point where you recognize people by it... whereas I don't notice and almost can't even process that at all... *but* I will almost never forget their voice as long as I'm paying attention enough to memorize it in the first place.
In my case, I have mild prosopagnosia. It’s not full blown, I can recognize features and what not, but can’t process them properly. Most faced look the same or very very similar to me, and I have to really focus and study a person’s face repeatedly every day for years to garner any sort of recognition to it compared to any other face. Combined with complete aphantasia it can be more difficult given my complete inability to visualize/imagine my thoughts or use the “minds eye” so to speak. Interestingly enough, I find it far easier to recognize and differentiate _non-human_ faces, such as animals or faces in artistic mediums that are highly stylized such as anime like jjba or cartoons like steven universe. I immediately have trouble with 3d and cgi though, even though if you took the same characters from a 3d animation and made them 2d, I would immediately have less difficulty and vice versa. I also have trouble with hype-realistic 2D drawings with the illusion of appearing 3D. For me, this says my brain specifically finds _processing human faces in 3D_ is the core issue.
It’s interesting, and I think it would be worth study to pin down finer differences in things like Prosopagnosia and what it means to different people with it.
1:13 You must be talking about regular people with faces. I'm a what they call a "super recogniser". I can match faces I've never seen before to other blurry images and tell when I'm seen a face even years before even after only seeing them once. It's weird. I'm the opposite of face blind like my wife.
Oh wow! @kenkire that is bloody amazing mate!
IDK if "super recognizer" is an actual term, but it describes me, as well. I always know if I've seen a face before, and it doesn't matter if I've met that person or not. If I see you on the subway or walking down the street just once, I'll remember your face the next time I see you, too.
I remember staring at the actress who played Data's "daughter" in Star Trek utterly certain I knew her, despite the heavy makeup she wore for the role, and finally remembered I'd seen her once years ago (way less makeup) playing a daughter on a single episode of Golden Girls.
.
The info is there, but sometimes it remains annoyingly on the tip of my tongue, as it were. In this case, it surfaced begrudgingly into my conscious recollection after about an hour of trying to fully retrieve it. Yet people's names often vanish into a mental void never to return, if they enter into my awareness (despite having literally heard them with my ears) at all.
@@iprobablyforgotsomething Same!
This is super interesting! I wonder how the 'know personally' matches to things like parasocial and online relationships today. I feel like I 'know' Hank better than someone like Jennifer Aniston (and have definitely watched his face for hundreds of hours), but would that trigger the same response as someone I've met in real life? What about my students who I definitely know personally, but have only ever spoken to through a screen?
What if you struggle to recognize people you know outside the context you know them from (ie work, school, etc). I really struggle to recognize faces. Outside of faces and names, my memory is above average. Is there something wrong with my temporal pole?
this is me too!
Same here!
I have that problem too.
I think that’s a perfectly normal phenomenon, nothing to worry about. Unless they are people you know very well, of course.
Some time ago I saw a woman pushing a toddler in a stroller, and I couldn’t remember what I remembered her from. The next time I went to buy a loaf of bread, I saw her behind the counter. I knew her as a shop assistant, not as a mum.
@@kellydalstok8900 If I was in your situation I would have never even thought the woman looks familiar
I hardly ever forget a face, but names I'm terrible with. I can see someone shopping once and then 6 months later see them again and wonder why I recognise them. Also found friends I haven't seen since Primary School - could still recognise them as 34 year old adults when I haven't seen them for 25 years.
Can you do a video on face blindness? Like, where there seems to be a hiccup in this whole pathway of recognizing faces?
As someone with DID I wonder how our brain would light up with regards to the temporal poles
Do fish recognize individuals
nearly EVERY face is a face I've never seen before... even mom, more often than not.
Hanks face is familiar, I have a Hank Neuron!
I have no trouble recognizing faces of people I know, but remembing their names is sometimes a challenge for me.
There might not be a grandma neuron, but you'd be damn sure there's a Jennifer Anniston neuron!
Having a “jennifer-aniston neuron” is just hilarious. When you call upon it, does it respond with _”Awn…”_ ?
Hank is a group of neurons in my brain. lol
So what you're saying is that there's a Hank Green neural clique inside my brain right now? Cool.
This guys looks a lot like Hank Green from other SciShow videos.
I can look at just about anyone and recognize handfuls of other people I know who look like they could be family. My roommate used to ask me to stop saying "hey that looks like so n so" every time we watched something. It's not just facial features though, it's cadence, gait, funny ways they move their eyes/nose/mouth. To me, they look SO MUCH like whoever else I'm thinking about, while the person who I'm pointing it out to is either like, "whoa I didn't see it at first but now it's all I see" or "no they don't, they have different hair/skin color/etc" but i definitely see something that's so familiar. I'm constantly worried I'm meeting someone I already know but forgetting where/how I met them.
I've seen celebrities in person, in public. I'd recognize them but my brain is like: where do I know this person? Did we work together? A few friends have had the same thing happen to them (I live in Hollywood)-- I wish there would be a study on this sort of phenomenon.
There is, in all of our brains, a "Hank Green" neuron... frightening
no
Why no?
@@RosheenQuynh I have not seen that face before
@@bunkbeds3001 Which face?
@@RosheenQuynh the face you're asking about
@@bunkbeds3001 😐 There was no specific face mentioned...
I want the ability to erase specific people from memory.
so many people have hank recognition neurons
Bruh so you could find out if someone has watched a certain kind of actor before by hooking them up to a brain scanner alright alright 😏😏
I'm confused, why the emojis?
@@RosheenQuynh oh u know
@@jacobvanmetre9283 I literally do not know
@@RosheenQuynh “a *certain kind* of actor”
@@4rkain3 Still confused.
so that's why there's a lightshow, Jennifer Aniston neurons get my brain fired up late at night
I don't know what my kids look like, but I recognize them easily in photos or real life.
So you really could edit someone’s brain to forget a person…
That sounds very promising.
Well, kind of, and in theory? If we one day have the precision technology to interrupt specific neural cliques, then yeah. But it wouldn't make you forget your memories of that person, it would just make you not recognize their face anymore.
This made me think of why casting in a movie, especially a series or franchise, is so important.
Who's face is Spider-man? Did you see Toby, Andrew, or Tom?
How about Dr. Who? Or James Bond?
First because this is how my brain works: Swordfish.
And second I wonder how false positives work in that mental system, I am sure I am not the only person who has been sure they recognized someone until you try to talk to them and they are not who you assumed they were, just someone you have identified as a doppelganger.
Probably just how you'd expect: they're similar enough that the neural clique for that person activates, making you think you know them.
@@IceMetalPunk And then those reactions are just not enforced so should occur less regularly unless you continue to see that person. Or so I would assume.
I'll forever cherish my Hank neurons❤😂
oh wow i've been interested in this exact topic ever since i saw an actor on the street and for a good solid 30 seconds, I thought I knew them, enough to approach and get ready to start a conversation. thankfully i placed them before i did that lol. brains are so weird.
bahaha yea I dont wear my glasses and was walking to go meet my mom somewhere and I thought I saw her walking towards me but wasnt sure so I kept walking towards her while staring at this woman just to get close enough to see she wasnt my mom and to feel completely embarrassed lol
ALL ROUND ME ARE FAMILIAR FACES...!
WORN OUT PLACES
This episode made me think back to the one about that study regarding how so many millennials likely have neurons dedicated to recognizing different pokemon!
For the last 7 years I can't remember anyone new I met/meet. I don't think I've had a stroke and I feel fine. I don't visit the doctors so don't have a clue. I can suss out who's related by looking at strangers and pictures and even smell who's a family but face to face, just not happening.
I think my brain has a problem, while I don't have trouble recognizing close family members and people I see everyday, if I see my neighbor at the supermarket I won't recognize him while I would if I saw him in his own garden at the other side of the fence. I once didn't greet my hairdresser at the supermarket because I didn't recognize her, same with a neighbor at the mall. If it's someone I don't see everyday and I meet them in a place I never seen them before my brain just doesn't make the connection.
Me too
De ja vu effect lol your brain trying to process memories
I was gonna say, I hope there’s more than one neuron, otherwise it might be easy to totally lose memories of someone
I feel like this is another one of those situations that scientists are over-complicating.
Our memories are known to be faulty, specifically because we only take in bits and pieces of information; it isn't realistically possible to recall all details of an event. When we do recall something, we're basically feeding that information back into the same parts of the brain that interpreted the inputs and reconstruct the memories in our minds. So for example if you try to recall a song you really like (but in silence), the auditory cortex will light up, just as it would when you were listening to it for the first time. You won't remember exactly what each instrument is doing, and you might even falsely remember the timing or key, but your brain can usually fill in the gaps of information.
I'm confident the same sort of thing happens with facial recognition. The fusiform gyrus lights up when trying to recall a face but I'm sure it's doing all the "encoding" work to remember a face too. Much like recalling a song, you only retain certain pieces of information about a person's face, so you only have an approximation of what someone looks like.
So really, the question isn't "how do we recognize someone?" but rather, "how are memories stored?" because as far as I'm concerned, the way the brain stores information about a face is not likely to be much different than how it stores memories about anything else.
It's interesting that you compare faces to music because I actually have perfect recall of music/sounds, so long as I'm paying attention, of both the vocalizations and instrumentals (earworm songs can be a real misery!). I hear them in my head as if listening to a radio when I recall them. And the timing remains perfect unless I deliberately alter and play with it for my own amusement, which I can do without overwriting the memory-file of the original sound (but cannot separately save the altered sound file without a great deal of repetition and effort).
.
I also have a decent memory for static images, including faces. But I can barely process (understand and translate to my own body) movement, let alone remember it or mirror-back dance moves or martial arts katas. And I don't read nonverbals (micro-expressions and body language) because I don't see it (meaning, I am not visually impaired but my brain-filter isn't primed to pick up on, translate and remember it).
.
As a final note, I have no internal monologue or mind's eye, which may be complete coincidence or may mean that the lack of the former gives me more brain resources to devote to recording/recalling outside sounds, and the lack of the latter may influence my difficulty with understanding and mentally replaying moving visuals. *shrug* The brain is an enigma wrapped in a mystery shrouded in a cloak covered in question-mark-exclamation-points, eh?
Ehm it's not just about memory.
If you ever heard about "This Man" image i wonder if it would spark any activity in a persons brain that has never heard of the "phenomenon"
The title reminded me of dream or nightmare man
Now explain how my second grade teacher recognized me in public and even remember my name like 20 years later.
I don’t believe my baby face syndrome is _that_ severe 😂
i wonder if this could help with trauma recovery
hmm interesting ... wonder why I have trouble recognizing faces when there're slight changes to it like a wig or some makeup or a beard/mustache
Bruh, the link for the app thingy didn't work for me.
I’d like to know what non-recognition or face blindness which I have would compare with people who can recognize people. I wish I could >
Can anyone tell me Why I get mistaken for people that strangers INTIMATELY KNOW like, ALL the time? I get stopped at the grocery store and at work all the time swearing up and down that we're /exactly/ the same. All without showing me a photo. Usually sweating that we have the same gestures. I have a yellow mohawk, so I'm trying to avoid this and yet no matter how much I alter myself it happens.
Dajavu might be conditions similar enough to trigger memories you don't recognize . Maybe we do remember baby stuff
Memories might be Arbitrary. Folding and complex of proteins and chemicals like a film chemical changes
Interesting
Dajavu is mostly likely partial memory
Thanks.
I was here
I'm unreasonably angry that you didn't even bother to MENTION prosopagnosia, Hank, the inability to recognize faces.
I have a sexy neuron
So if ghost hunt those grand mother neurons more like coco
A "single neuron" ? Nope aint buyin it.

HA I'm going to be lost in the sea of comments
See myself in a few years!
See Alzheimer's.
no
Is there a term for "having that kind of face that always reminds people of someone else they know"? Because, apparently, that's me. ¯\_(ツ)_/¯
