Brain cells mobilize sugar in response to increased activity
medicalxpress....
"New research is providing insights into why the brain is so reliant on sugar to function. In a study published Jan. 19 in Neuron, a research team led by Weill Cornell Medicine investigators discovered that brain cells recruit a specific sugar, glucose, to fuel the transmission of electrical signals that enable people to think, breathe and walk."

isn't it funny that we're using our brains to find out how our brains work lol
#sentient
That's why spiritual people say you r not even the body and not even the mind👍
the body isnt “ours”. sometimes wonder brain control me or me.
lmao
quite ironic, my neurons are firing when i think of my neurons firing xD
ikr like it literally named it self
2:15 no ion is trasported through the synaptic cleft, it’s a whole different process there. the presynaptic neuron releases molecules of neurotransmitters in the synaptic cleft which interract with chemically gated channels on the postsynaptic neuron membrane. as the molecules of neurotransmitters dock/bond with those channels, they open up which can result in the flow of sodium ions into the postsynaptic cell and therefore, creating a postsynaptic excitatory potential.
I was thinking the same thing, also they got another thing wrong. The mitochondria doesnt use glucose it uses NADH which is a byproduct of glycolysis.
True
Loving the new style, Seeker! Keep it up my human friends!
Life Noggin its you hi!!!
Life Noggin I love you
Ayyy life noggin!
Thanks so much, Blocko!
eyyy life noggin hehe
Only 90s kid will remember when this channel was called "D news"
Crespo2689 - the D is silenced
... Oohh, I wondered why I had been unsubbed of Dnews and that suddenly I was subbed to Seeker... That makes more sense.
Next month no one will remember when it was called Seeker if they keep going like they are, they'll have changed names 3 more times by then.
Crespo2689 - I thought they changed it to NowThis??
Twiistz, That was the channel which used to be Seeker Daily (and I think Test Tube or something before that) they are just trying to confuse everyone.
Ions do NOT travel through neurons.
I know it can be confusing saying that the change in potential is what is moving (= electric signal) when you just stated that it's not electricity, but please...
If ions were to move, thoughts and other nervous signals would be sooo slow!
For those interested: basically ions just move locally inside and outside of the membrane of the nerve-cell, causing a shift in polarities that "travels" along the axone (the "stretchy arm" of the neuron) and once it gets to the synapsis it releases some other molecules that are in the vesicles. Those molecules are caught by the next neuron, which lead to another bioelectrical signal along the arms of the cell. And so on.
Nice explanation. Ions are moving, just not how he thinks they are.
I guess they just decided to simplify for the audience. I hope it went that way, at least.
CapitanOdisseo do u think that the amount of sugar in our blood effects our brains? i noticed that sometimes my brain works so smooth with no need to think hard, and sometimes i have to push it is much is possible to think, this problem effects my life sooo bad , if u know something would help?
There surely are some effects but sugar is not the only thing affecting your performance: fatigue and stress for example can affect you as well. I'm not an expert in human physiology though, if it really bothers you, you should ask your doctor for an advice.
***** I'm willing to get some help , thank you so much
If the brain runs on sugar then why are some people so bitter? We should all be sweet to one another.
Master Therion haha ha ah ahah haha great joke ha ha
Master Therion lol
Master Therion I want brainssssss...
Their brain run on SHIT!
Master Therion 😂😂😭
So hard thinking of brain requires more glucose. i finally understand why 'L' from death note eats alot of sugar. Thanks seeker
rithik gandhi THAT'S IT!
rithik gandhi I knew this all along.
It also explains why he never uses socks or shoes: it prevents overheating/sweating (blood carries the heat out of the brain to the skin for passive dissipation).
Well actually it's more like his body creates more insulin than average people
No? Brains use almost the exact same energy when at rest and when thinking hard
Actually, an impulse that moves through a nerve, the thing that you call the 'ion' or electrical signal, is actually a chain reaction of potential difference between the outside of the cell and the inside.
I reckon the ATP is used for opening/closing gaps in the membrane for ions to pass through and to restore the potential difference, so that it can receive another impulse.
Maybe it's just me but I felt like you did not really explain it too well.
Yea this was the worst explanation possible for how a neuron fires.
Much of the explanation was vague and misleading
@@yakarotsennin3115 where can I find more information about the thinking process in the brain?

Hey Trace, can you do an episode on this topic but when ketones/fat are the bodies main power source. I.e. How the brain functions in the absence of sugar and why the brain is less likely to trigger a seizure when running off of fat.
When he said that something could jump out at any moment i was READY for that JUMPSCARE
So if I think hard enough...... I'll lose fat?
no because if u want to not be fat u need to reduce the amount of fatness in your body, not suger
The Enigma Actually yes. So long as you don't input more food than you burn by thinking.
+bar lupo - fat is just an energy reserve, so if I use all of my blood glucose, then the rest of my body will have to lose fat
Actually yes.There was this chess match with these two players and one lost a lot of weight. www.chessgames.com/perl/chess.pl?tid=55015
Though it's extremely unlikely to lose weight by using your brain a lot. Just do physical exercise.
No. Biochemically the body is incapable of generating glucose of out fat, so if your body runs out of glucose it switches to ketones as substitute (meaning, it mostly feeds of proteins). Fat's are primarily metabolized by muscle cells.
So the trick that most people don't seem to to understand to loose body weight is simply to have a lower intake of calories over a long time, than your body uses.
Eat less to increase caloric intake or alternatively burn more calories by bodily activity and you'll slim down over time.

this is a pretty channel you got here...life in a fundamental sense is just complicated chemistry unfolding in all its glory...the electrochemical mechanisms in my brain have my respect
Hmm, this is food for thought. No, wait. Glucose is food for thought.
LOL ^_^
haha! 😄
This is the best and most elegant presentation of how the brain works I've so far seen. Though most of the matherials are pre-college.
I just love the visuals of my brain sending signals to everything telling cells what to do. Amazing! And now they have visual proof of brain signals, it's crazy, almost like the internet or fiber optics
I would use my make-a-wish on this guy. He's my hero. Thanks Trace!!
Maybe that's why you get so hungry while playing video games. Your brain is on high alert thus burning glucose making you want more. Nice!!!
**autistic screeching**
My son is doing a project about brains and he said just watching this video he was already done with his project thanks seeker
2:08 I could watch this ALL DAY
I wonder if thoughts make a sound and if we could use that to hear other people's thoughts somehow
Enough with the 'DNews', it's 'OldNews' now. Just accept Seeker and move on, the world isn't going to end just because the name's changed. The contents and topics are still interesting and it's still Trace hosting the channel. Though I do miss Jules or Julian or Julia or most of the old casts but lets just keep supporting this channel and hopefully they'll return!
When I see Trace smile, I can face the world. You know? I can do anything!
Ketones baby! Hey Trace @Seeker can you guys do some videos on ketones, both endogenous and exogenous? Cyclical keto diet may be the wave of the future (and the past if you were a caveman). Love to see some content on that stuff!
the mitochondria is the powerhouse of the cell
I've definitely noticed not eating like I normally do has effected memory negatively and overall function of my brain.
Eating 1-2 good meals a day plus fruit is the go. And a chockie here and there to keep you happy :D
how does the brain operate while in ketosis?
.
SuperAtheist In the absence of Glucose molecules to generate Acetyl CoA, ketone bodies are used to generate Acetyl CoA, the molecule that enters citric acid cycle to generate protons which are used in oxidative phosphorylation to produce ATP.
SuperAtheist the protein is broken down to amino acids which are converted to keto acid and urea. The keto acid is used to convert to Acetyl CoA which goes into the krebs cycle and the NADs get reduced which are transferred to The ETC where oxidative phosphorylation takes place
A.J Mathew wow well said!!
Duy Tran i replied too you know!
Ahmed Saif lol I was fixated on the first one. Yours also great. I love these informative comments
It's really nice that Seeker has listened to the community and has Trace as the dominant host (again)!
This is a huge over simplification of how mitochondria and neurons function.
Neurons communicate via chemical neural transmitters that travel across the synaptic cleft, inducing a excitatory or inhibitory response through altering the voltage potential between the cell interior and exterior (of the neighboring neuron). This change in voltage potential is what propagates down a neuron's axon (in flux of sodium ions / out flux of potassium ions)
Mitochondria utilizes electron carriers and O2 to run the Electron Transport Chain, which leads to the production of ATP from ADP. The breakdown of glucose is necessary in obtaining high energy electrons for the carriers, yet this is done outside the Mitochondria.
my brain is currently running on ketones!
And this is what those ketones are doing to your body:

You will notice that some of the side effects include: inflammation risk, kidney stones, muscle cramps/weakness, hypoglycemia, low platelet count, impaired concentration/cognition, osteopenia/osteoporosis, and cardiomyopathy.

Mike C stop spreading cherrypicked studies dude... there is lot of evidence that the ketogenic diet is not harmful at all... look up lowcarbsport ( its a youtube channel aimed at doing research about the ketogenic diet)
Veganism is the superior diet by far, so it doesn't matter.
veganism isn't a healthy diet, you're missing micronutrients such as omega-3 fatty acids, iron, zinc, vitamin b-12. Our bodies are meant to eat meat.
tell me again how iron isn't in spinach, b12 not in seaweed, zinc isn't in grains and omega3 isn't in chia seeds
Awesome video, please do more on the brain/neurons!
Hey, what is the role of ketones on the brain? Is it purely as a fuel? Or does it complement a process similar to this?
I can totally tell when my blood sugar is low because my brain grinds to a halt. I can't think as clearly or as quickly, I have trouble understanding English, and I can't remember anything.
I'm pretty sure that neurons do not fire ions out at neurons across the synaptic gap. Neurons send biochemicals called neurotransmitters across the synaptic gap. That is an electrical to chemical transduction process. Ions go in out of channels that cause the neuron membrane to depolarize. But there are no ions fired out of the neuron. You can take my word on that.
"If you are low on sugar it makes it harder for your brain to work"... I guess Ketones don't get a lookin on this episode of seeker. Come on guys, more seeking info and less hiding it from us. If you want to inform and educate, either do it with enough information to do a good job or don't bother.

I'm fan of the show. Would like to see a show on epilepsy on seeker plus. I think there is a lot of info on in you could talk about.
2:44 Can't believe mitochondria burn glucose babies. RIP. (I make science vids so a cheeky sub will be appreciated 😂)
yes, that sounds awful, but it make me wonder do you need a male and a female glucose to get a glucose baby, are-they asexual?
also what are we fetching to glucose for them to make those babies? why do we need more glucose?
Glycolysis happens in the cytosol, so the glucose babies are 1st chop in 2 then burn in the mitochondria. For maximum efficiency!
Just think what the midichlorians do...
Exactly 😊 you can design your own life
It is not an Ion being "Thrown" from one synapse to the next. The impulse releases Neurotransmitters that can cause an impulse in the receiving Neuron. Different Neurotransmitters have different effects on the receiving neuron and this his how they communicate!
T 2:13 "it releases an ion via..." - the neurons release neurotransmitters (NT), not ions. The NTs open specific channels in the post-synaptic cells allowing ions to enter. Nice video.
Acetyl Choline does it via chemical means and also there is electricity sometimes transmitting directly.
I always feel that when I go on a high nutrient fruit binge (kiwis, bananas, papaya, brocolli, spinach) my physical endurance as well as mental is boosted
Brain also functions well with Ketones not only glucose
This makes me wonder. I see and hear so much about the ketogenic diet, that trains the body to run on fat instead of glucose (carbs). Proponents claim clearer thinking and better sleep, as well as losing body fat, since ketosis makes fat your body's fuel.
I'd love to hear Seeker's take on ketosis.
Loved that animation thou x'D
what about people with insulin resistance or diabetes? how does this affect their brains on sugar?
Cell Biology gets super interesting when you begin to try to imagine how small these things are.
I know that when my glucose levels are low, I get agitated easily, it's harder to concentrate, and even communicating with others is impaired. I have eaten a banana when I've been like this and it's helped, but of course it doesn't last long. Though, in a pinch it can help a lot.
can also use ketones, which are made in the liver from fat
Great video. Only one aspect is worth to take into account... Mitochondriae work best with ketonic bodies. Glucose is not a must neither a best for brains.
I haven't looked into it. But I wonder what is the byproduct of this usage of glucose? Do they release energy in the form of infrared? What else? I have noticed my head warming up during long periods of critical thinking (an exam for example), but that could also be a byproduct of stress itself.
Yes protons are released I believe
The exam likely causes an increase in glucose and oxygen use (cellular respiration) because neurons are more active.
These neurons require more glucose and oxygen, so blood flow is increased to the brain.
That's a possible explanation for the head warming, as blood vessels dilate
Brain is the instrumental cause of “Thinking” but the material and intelligent cause is “Consciousness”.
Hey
So I was just studying this in physiology
And I have a slight correction, or maybe I need the correction
But GLUT4 (Glucose Transporter superfamily 4) are Regulated by insulin and found in muscles and adipose tissue mainly, the Glucose Transporters in the brain cannot be Insulin dependent, otherwise all diabetics who have slightly low insulin exposure would die almost immediately.
Clinical depression and ADD, my brain burns up every time I have to really think. Any ideas on how to get organized and motivated to... use my brain on important stuff?
So you're telling me all those Snicker ads that kept telling me I'm not myself when I'm hungry are dead accurate? wow
Well done video. Critical information left out, but certainly a start. I will vote for you on webby awards
Trace, YOU ROCK!!
Thank You very much. Very educational and helpful.
Mitochondria is the powerhouse of the cell.
ty-when we leave our body/pass on we don't take our brain with us-we are ENERGY:pos&/or neg-LOVE
I am just taking a neurobiology course and you can't beleive how much the nervous system is complicated and accurate and to some one come tell me oh this thing evolved from a single primitive cell millions and millions years ago I would almost kill him this is a fantastic creation and it is humilating to us and to it to say it all came by chance. just appreciate your minds and give them some respect.
Uhm whoa! nope! Big mistake at 0:57, the central nervous system (i.e. neurons) synthesizes GLUT 3, not GLUT 4... This is a major distinction since GLUT 3 is not insulin dependent and has a low Km (high affinity for glucose). ...In regards to muscle GLUT 4 is correct...just not for neurons... Can someone back me up here
No _intro's; yaaay!!_
Really very nicely explained

electric current that we use as AC and DC, like AC can we have a current that three alternating waves to each other as AC has two alternating waves to each other to create AC current.
Pretty good.
But at 2:14 and again at 2:24 he makes the same mistake, talking about the presynaptic neuron releasing an ION that is then received by the postsynaptic neuron. What he meant to say - and actually said at 1:45 to 1:53 - is a NEUROTRANSMITTER.
how brains work: PLOPP! SWOOSH! mieee...

Holy shit, really?
Dhruv Verma me too but idc about the name
# SOMETHINGAMER # I watch it more now
Interesting but riddle me this: what turns thought into a specific language?
Just about correct, however, the "messages" are simply action potentials, or electric charge in motion (current). It generally takes many presynaptic neurons synapsing with a post-synaptic neuron to create a "spike" in it. It, in turn, becomes one of many neurons to send current to other neurons to possibly create another spike. It is these patterns of spiking neurons over time that is called "neural activity" in our brain. These patterns somehow create everything we perceive externally and internally, felt emotions, dreams, actions, behaviors and thought, and throw in consciousness.
what abt intermittent fasting? i eat once a day and i dont feel like i am less able to think before i eat or smarter after i ate. same with sports
hi, how about publishing new articles about the mitochondria uses fat instead of carbs? about ketosis? that really more up to date!
When the glucose is brought into the cell by the gluc 4 and the mitochondria breaks it down , are photons released too?
Did you know: The mitochondria is the powerhouse of the cell. *The more you know*
At the most fundamental level its the movement of charge!
that sound was really satisfying.. eeewwwnnn
it seems like you should have mentioned ketosis
aaand what does mitochondria burn? ....beta hydroxybutyrate

How long does it take for a ketogenic diet to do all of that. Show me some scientific journals, show me the proof!
Funny thing is I was actually "flexitarian" without even trying before I went keto. It's more natural for me to eat that way, but I was having trouble with some things and fueling for long days of mountain biking, so I wanted to try fueling with fats, and it worked for me. It takes a few weeks to adapt, but after that you don't have to worry about ever running out of energy on long days of cardio.
Low on sugar... i've been on a low carb diet for the past 2-3 years. Vegetarian low carb to that! If anything my brain became more agile and i also have a lot more physical energy along with much improved cardio (without training anything extra to get it). Weird huh! :)
Seeker gives a lot of good taste. good will vital energy so as to inspire the world to develop ither in the Digital World or the Green Environmentalism. i like how Seeker can handle the two things at the same time and inspire to move the livido so as to go on working and studying.
How much do I need consume sugar before studying ?
Do one create own thoughts or are thoughts already in the brains just one to discover them?
They can also run on ketones
Although glucose can be good for your brain, too much of it can make your thinking foggy. I've eaten a bag of skittles, and drank a can of soda and noticed this. My eyes turned bloodshot red and my hands started shaking.
Josh Jones thats too much sugar in one setting. u need steady sugar like fruits with fibers and other healthy things. candy is bad for thinking
Sounds like you consumed a significant amount of easily accessible glucose likely in the form of high fructose corn syrup.
Soda typically falls between 30 grams and 75 grams, which is practically your entire days worth of sugar in a single setting.
The fructose enters the bloodstream quickly causing a spike in blood sugar levels.
Electricity is just a side effect of the chemistry of neurons. The firing called "action potential" is a chemical wave (sodium and potassium), the end of which trigger the delivery of a neurotransmitter, another chemical which accumulate in a small reservoir, the synapse. The neurotransmitter is either exciting or inhibiting allowing analogic addition or subtraction.
After a time window such as 10 ms, the next neuron sharing the synapse will fire, meaning the addition win or remain silent, the subtraction win, the comparison between add and sub is negative, no match.
The synapse allow each neuron to remain fully enclosed hermetically, like any other cells so that a sick neuron keep its diseases for itself.
The synapse also absorb the electric shock to prevent exciting accidentally the next neuron.
The next pulse has to be the result of the chemical battle in the synapse, the electric shock of neurons firing is just unwanted noise.
Hmmm but the synaptic cleft is releasing neurotransmitter molecules, not ions. Calcium ions only serve to open the gates for the neurotransmitter to be released. Am I wrong?
thanks. i like your channel's worthiness
Glucose is not given to the mitochondria -- molecules derived from glucose eventually enter the mitochondria after the glucose molecule undergoes several reactions. Technically, an organism does not need mitochondria to produce ATP, as it can happen in the cytoplasm of the cell via glucose catabolism and doesn't even require oxygen (anaerobic glycolysis). However, this method of ATP production is by no means superior, as it produces much less ATP per glucose molecule than aerobic metabolism (occurring in the mitochondria). Its advantage lies in the *rate* of ATP production, which is useful when energy is needed immediately.
Absolutely correct
What about ketones?
I love this channel. Quite dearly.
Thanks for reminded me that once the semester ends so does everything I've learned in psychology/neuroscience, have a like.
But if you're fasting or doing some kind of ketosis diet, your body will eventually convert parts of itself to use as energy for the brain, so never fear. It's a lot harder to go down in flames than you might think. The only immediately threatening ingredient (not dangers but ingredients) is lack of water.
just found out why i can't be smart *cos those vesicles always get stuck in the synaptic gap,evaporate and never reach their destination*..Thank u D news
Can u do an episode on brain plasticity please?
hi what about ketones
