Importance for Human Physiology
nice … I think I understand…. but how da hell did you figure this out?
never mind,,, do not know how to do this neuron brava kinda thing…
nice vid gonna have to repeat this for awhile
I don't know how Kenickie learned so much about science, but he can trigger my switch open to absorb any day.
Something I have only recently learned about myself, is that I probably am affected by "visual snow". I thought it was everyone's experience, to at all times see a continuous field of tiny red, green, and blue dots, until I said something to my wife about it, and she hadn't the slightest idea of what I was talking about. The little colorful dots are almost overwhelming in the dark; I don't really see "black" at night, just red, green, and blue. In the day, I see quite normally, though if I sort of stop focusing on what I'm looking at, I can tell that it's really just the RGB dots.
The most underrated channel
Alright chill, you're not cool enough for a leather jacket
Evolution likes spaghetti code
Very nice description!"I'm always fascinated by how complicated biochemistry is" Yes, most things are more complex than originally perceived…
10:38 I'm not sure I understand how the output of the Long or Red cones, which generate almost no signal in the violet frequencies, but somehow post processing amplifies that signal, but only in the violet. What tells the post processing that it is receiving the violet frequencies and to pump up the volume, but don't pump it up when it's receiving blue?
The wonder of this deserves two, three,…videos if it needs. I saw this video several times and anywise i didnt get the most of it…Being younger i studied colors theory as first chapter for color tv theory, then Feinman lectures shows the back of an eye conections…then you: thats all for people like me which is not a phisician. I hope you consider a longer video being more compasive with people less intelligent like me.By the way, would you explain the way we distinguish differents intensitys of light when neurons works with principles yes-no or "all or nothing law"?Thanks again for taking us (or try at least) to this century level!!!
I think Steve is suprachiasmatic
Another great video. Cheers for the share
2:25 "all-TRANS-retinal"?! Demonetized.
Your illustrative visualisations in this video filled me with a ridiculous amount of joy, while still learning so much. Thank you #DayMade
Why are you wearing a leather jacket indoors though?
Great video. It is amazing the parallels between how those systems work and things that we have designed like electronics and batteries. I guess it stands to reason as many of the chemical/electrical processes are the same.
It also kind of illustrates that it would be very easy for each human to perceive the same color slightly differently. While the wavelength of the light is pretty immutable, the quantities of different light-sensing cells and their effectiveness in each person could allow for a pretty wide variation in color sensitivity.
Great video about something I've often wondered about, cheers!
Also, when you have to make a video on the molecular basis for vision and 4, but star in "Grease" at 5:30 🙂
Great work as always. What happens with colour blind people?
Why are there twice as many noticeable colors between red and green, than between green and blue?
The long chains of molecular steps in biochemistry don't persist because evolution requires steps. The "evolutionary" process is overhauled all the time. Ie Bob changes but Tim does not, but Bobs adaptation is a little more costly than it is valuable, eventually Bob's lineage diminishes via natural selection. And if there is a way to keep Bobs adaptation without the extra steps, that pathway will eventually occur and be selected for. There reason that there are these long chains is because each step has multiple branches that lead to alternative signaling, or steps that lead to noise reduction in the signal, or multiple steps are actually more energy efficient than a single step. 90-95% of the time when we see "Junk" in nature it just means we are really just ignorant of it use.
This was illuminating 😎
Why can we only perceive the three basic frequencies of light if the proteins can change the molecule to react to any light?
Hi Steve!You are doing awesome videos, that seems you have put alot of hard serious work behind before presenting it.
Please!Can you and maybe with some of your youtuber friends, dig really deep into this topic and do a real openminded investigation.Truth, fiction or somwhere beetween?Topic: Earthing – Grounding
BYU is the school I dropped out of!
I have always been obsessed with electromagnetics and vision but I never new much about the proteins. Thanks!!!
An unorthodox vision of spooktober.
Steve is so handsome it hurts. Help.
I know how my mum feels when I talk about science now.
Biology is so boring and lame.
Sometimes your videos go beyond my capacity for absorption capacity/comprehension, but I stay til the end because you are such an excellent presenter!
Hang on! Is that… the Fabric of Reality at 5:40? (You know, the one from the gravity waves video?)
Great job explaining this topic! Always surprises me how much red there is in what we consider peak blueness (~460nm), and how little there is where we start to perceive purple. If you ever do a followup, it would be cool to talk about that recycle time and how it relates to dark adjustment delay and why it's unpleasant to exit a theater in the daytime. Something I've never learned about is why color processing happens up front in the eye, but the first visual cortex is only concerned with edges and differences, yet the color information is preserved and properly processed way down in the fourth cortex! I remember something about the eye actually only transmitting spatial color differences, so maybe that's how long it takes to integrate the differences into a persistent color picture where we can talk about solid color fills and gradients and all that.
Sooo, yeah, definitely do a follow-up!
What do u think dogs perceive colour as?
a-ma-zing video , absolutely loved it! so clearly explained, not too slow, not too fast, not too simplified, included everything i wanted to know, thank you!
Not just tiny baby steps, but random ones… leading to such strange complexity.
Amazing video! I do have a question though. How is magnitude represented? If each cone is on/off, and all cones of one type are sensitive to one part of the spectrum, wouldn’t they all fire at the same time when exposed to a wavelength in that region? Does the sensitivity of each cone vary a bit, and then the total number of cones activated indicates how bright the light is? Or, is it not actually on/off but more of a continuous representation of activation? Or, is it neither of these?
This is comedy genius
Who is here from smarter everyday?
WILSON Sent Me !!! SUBBED !!!
Destin from SmarterEveryDay made me subscribe to you! 🙂
It takes God Almighty to create the best chain reactions.
Greetings from a colourblind viewer! As such I’ve always taken great interest in how the eye works. Thanks for so simply expressing the molecular mechanics.
I am an anomalous trichromat. Meaning I have all three types of cone cells, however the “peak frequency” you mentioned for my individual cells is different. Specifically for me my medium (green) cone cell. The technical term being Deuteranomaly.
You really wouldn’t believe how heavily your brain relies on those “post processing effects” to determine colours.
Great, now I'm going to have dreams of pastel ghosts. Thanks Destin.
SmarterEveryDay Army coming through.
Hey new sub here! Sent from SmarterEveryDay!
BYU as in Brigham Young University?
amazing video. Thanks
Hey Steve, surface scientist at QUT here, you molecules with double bonds don't actually bend and flex like that the Pi-Pi bonds (the second covalent bond) actually locks its orientation.
Destin from Smarter Every Day sent me😁
I just saw the Hoover institute saying evolution is mathematically impossible, rather intelligent design is much much more likely. Can you investigate?
Sent here from destin thanks for helping make me smarter every day
Hello I’m a fan of smarter every day and now a fan of you! I’m late but better late than never!
This explanation made so much sense! Thanks! Just arrived from Smarter Every Day. You've definitely earned my subscription.
hey wait a minute – is that the orange lycra from the gravitational waves video?!?
I used the doorman analogy for my senior project in school about Cystic Fibrosis
Hey Steve Great Video! We learned all of this in Medical school and the crazy thing is that in the retina not only the detection of light but also the processing of this information happen. You have different Horizontal cells which become activated by the photoreceptor cells and inhibit surrounding photoreceptor cells to create contrast. That is for example why dark areas seem on the edge to white areas much darker than being surrounded by dark areas. Fun fact: Most of the Proteins you have mentioned are reused by the body in different locations. cGMP in the nose and tongue for senses. Transducin which belongs to the family of G-Proteins are used in the Sympathicus(fight and flight) to increase your heart rate, constrict your Arteries,…
I shouldn’t have had a double Johnny Walker shot before watching this.
The best visualisation of protein ever!
So our Brain actually calculates the integral between the cone types?
what do you get if you combine max payne and vampire guy from "preacher" u got steve
10000th view wtf
Eat your carrots, children.
Gonna get a beer and watch it again 😀 Cheers mate! 🙂 I liked the way you were holding the door haha
*doomsday visions from highschool chemistry emerge*..
Well. He looks nothing like my chem teacher phew
Also he explains things quite well.
Why does a car feel like a beating drum when the windows are open?
If you want to imagine what got looks like. Turn on color inversion on your device, and then watch steve mould talk about anything.
Steve looking sexy with that jacket
Question for you Mould man, why, does a saucepan of boiling water steam MORE when you turn the heat off? It's bugged me for years.
After that complicated explanation, you still believe in evolution?? 😉
These days this is the best way to get smarter everyday
Somehow, i think he looks like the youtuber Fitz. Or at least a little bit.
Steve definitely smokes weed..I know a stoner when I see one
12:04 this is actually incorrect. Its a misconception that evolution is some steady gradual thing. Actually, pretty big evolutionary changes usually happen to a large portion of a population in a very short time
And we are told all of this amazing molecular complexity and order came from "random" events? (Obviously not through "concious" trial and error).
I'm sure you are well aware of this, but at 3:14 you could have clarified better that the energy and frequency of a foton are very closely related and thus are indicators of basically the same properties. Actually, the energy of a foton is completely determined only by its frequency (or wavelenght):Energy = (Plank's Constant) * Frequency. Cheers!
You comment on how it is fascinating that there are often so many steps in going from one biochemical state to another. Like in reverting the retinal back to its' unbleached state (11:36). The steps to "re-sensitize" a rhodopsin molecule take a tremendous amount of time (like 30 minutes!). I have trouble imaging how/why it can possibly take that long! But, then, the fact that it does take that long may be evolutionarily intentional; the experience of going from a dim environment to a bright environment can include momentary blindness (or close to it), so having a large percentage of your rhodopsin not able to respond may be a good thing in a bright environment.
0:31 i swear you look exactly like a mad scientist smiling at his own creation.
Every time at the end Nature gets the credit, as if the Nature itself is the Creator. I don't understand why keep God out of equation each time? Oh, we have evolution theory! Maybe God chose that way of creating and some come and say oh it's not God, it's natural processes no need to believe in God! Well, these complex chemical stuff all over the earth itself prove some sort of "intelligent designer". Look at what Richard Dawkins got to say https://youtu.be/hQdVrpdJxf0
You're still promoting nordvpn??
not complicated at all.
WOW !!! Mind blowing I never thought it was that complexe ! Still weird to think that this causes us to see at all it seems so abstract !!!
Is the blue light that wakes you up straight up blue? I’m assuming it isn’t, but I’m asking as it would be interesting to set my lightbulbs to what ever the appropriate RGB value (if possible) in the morning to wake up.
I wonder if the dinosaurs could even see colors, and if they could, if they would see an entirely different spectrum..
It's done well.https://blog.naver.com/7heppy7

Copy and past from other video.3:59 ~ that was really the best video ever. #WellDone! ~ a #newmystery, to apply to an #oldmystery, the intrigue humans who see different, looking at #opticalillusions of the #colourblue, in and among human species, these colours or shades of #Blu confuse or comfort, or more easily value differences. = its not a gradient, even if it is. this blue is not that blue. #SteveMould says all colours are a single molecule in the eye that gymnastically bends differently.
#WeAreOneColor and We are a #Molecule, and definitely not a #Mineral pieced together with #Silicone or #Metalloids to bend like a prism, producing a different refraction pulse on the nerve.
Could there be a way to the alter the proteins so that they are most sensitive to light outside of the visible spectrum, like UV or infrared? That'd definitely be something interesting to consider
How about a video about the 4th colour cone? The one that is really a genetic mistake that only women can have that gives that lucky sod (IMHO) an extra colour let’s say or to see a much clearer distinction between two colour that to most of us, looks like just one colour. So bio chemistry and genetics all in one! 👍✌️
It's scary how many similarities the universe has with the way computers compute things, the not gate cells work in a very similar way as the logic gates do on cpus, and then how quantum mechanics explain things in "simulation theory" and etc, such as the superposition property and the way we manage memory in software (pointers and how they only store the address of data which then allows the software to put the data in memory using pointers whenever there's a need, instead of constantly keeping it in memory, similar to how quantum objects behave differently when observed) … Makes you think… Bit by bit, if you stitch things together from different fields of studies, more and more discoveries lead to credibility to the simulation theory. I ain't a believer myself, but it just makes you think, maybe the idea is not so absurd after all…
I need some of those super-charismatic nuclei 😉
5:48 Is that orange blanket the fabric of space you've used in the gravitational waves video?
Oh its a aldehyde makes sense now why it ends with al
This video was really informative and explained really well the biochemistry of eyes. It got me thinking about a few questions, one of which was how would the proteins affect retinal in a red-green colourblind person and how would the (processed) wavelengths look like?
Your larger protein looks suspiciously like a bloke wearing a white bedsheet.
You are a wonderful guy and a good explainer. Chemistry is my life. ❣
OMG, you're gorgeous!
