Does Thinking Really Hard Burn More Calories?

"Unlike physical exercise, mental workouts probably do not demand significantly more energy than usual. Believing we have drained our brains, however, may be enough to induce weariness."
Human Brain Loses Billions of Neurons in New Analysis
www.livescience.com/18749-huma...
"The whole human race just got a little dumber: A new analysis of the number of neurons, those brain cells that transmit thoughts, in the human brain has come back with a staggeringly lower number than thought -- 14 billion brain cells fewer, about the size of the baboon brain."
Brain cells mobilize sugar in response to increased activity
medicalxpress.com/news/2017-0...
"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 😂😂😭
This is my favorite channel on TH-cam. Keep doing what all of you do best!
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
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.
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.
mitochondria is the power house of a cell
これはペンです。
*are
It produces the ATP normaly it is.
Are*

Awesome video, please do more on the brain/neurons!
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
I would use my make-a-wish on this guy. He's my hero. Thanks Trace!!
When he said that something could jump out at any moment i was READY for that JUMPSCARE
Midichlorians are the powerhouse of the cell.
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
Trace your awesome man!
You make me feel like supper dad to my kids. When I can answer there questions. And when we look you up for answers!
Well done video. Critical information left out, but certainly a start. I will vote for you on webby awards
Everything you do -
Everything you encounter -
Everything you experience -
------- is changing your brain --------
Thank You very much. Very educational and helpful.
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?
Loved that animation thou x'D
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 love this channel. Quite dearly.
Great video , thank you
It's really nice that Seeker has listened to the community and has Trace as the dominant host (again)!
My son is doing a project about brains and he said just watching this video he was already done with his project thanks seeker
Trace, YOU ROCK!!
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
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!
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.
That's amazing! Hi from Brazil
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.
"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.
This is what those ketones are doing to your body:
20314-presscdn-pagely.netdna-ssl.com/wp-content/uploads/2015/05/Ketogenic-Diet-Literature-Review.pdf
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.

If your current diet works for you then great. But the science says that your brain would work better on glucose.
Really very nicely explained
Hi Afreen, you can also check our video on “How The Mind Affects Everything” at th-cam.com/video/eLQU4b06HUM/w-d-xo.html
In this video, you will learn how the mind affects your emotions, the physical body, and your soul experience. We also share 2 steps to create alignment and congruence in your life so you can experience your desired reality and overcome any issues that could be holding you back.
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...
thanks. i like your channel's worthiness
awesome, I love things about how brain functions
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.
Thanks!!!
I missed you man welcome back
nice one, Trace
Thanks for reminded me that once the semester ends so does everything I've learned in psychology/neuroscience, have a like.
Very interesting!!!
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!
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?
2:08 I could watch this ALL DAY
Can you compare how the neurons work compared to transistors and circuits do when calculating 50+50 for example? :D I wonder if the neurons have the same logical process as transistors and such :D
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**
Nice job
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.
very informative
Acetyl Choline does it via chemical means and also there is electricity sometimes transmitting directly.
Absolutely correct
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.
I wonder if thoughts make a sound and if we could use that to hear other people's thoughts somehow
When I see Trace smile, I can face the world. You know? I can do anything!
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.
Great video
Exactly 😊 you can design your own life
the mitochondria is the powerhouse of the cell
my brain is currently running on ketones!
And this is what those ketones are doing to your body:

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
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
if I'm not mistaken glut 3 is found within the brain (amongst neurons)and glut 1 at the bbb where as glut 4 which is insulin dependent is found in muscle and adipose tissue... can someone please explain ☺
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!
This guy is my favorite D News/Seeker host!
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
I really would love to know what you use to create these animations? Does anyone know?
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
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.
When the glucose is brought into the cell by the gluc 4 and the mitochondria breaks it down , are photons released too?
great video
that sound was really satisfying.. eeewwwnnn
Cell Biology gets super interesting when you begin to try to imagine how small these things are.
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.
Really cool T-shirt!
hi, how about publishing new articles about the mitochondria uses fat instead of carbs? about ketosis? that really more up to date!
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.
Great Requiem for a Dream reference.
what about people with insulin resistance or diabetes? how does this affect their brains on sugar?
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.
WOW that's so cool
I have a question:
Why do hair on legs or hands grow when we cut them?
you're just saying same thing that we learn in school nice.. 👏👍
How much do I need consume sugar before studying ?
Daamn Trace, ur all over the place! Lol right on n great video.
So where exactly is glucose present? Is it present all over the brain so that Glut4 can take it up whenever it needs it?
When we think, an ion influx occurs at the neurons which then leads to an action potention. But what triggers the ion channels on the nuerons to open when we think in the first place? :///
how brains work: PLOPP! SWOOSH! mieee...
I watched your videos more when it was called DNews 🤔
i wasnt even aware they switched to seeker until someone told me
+Dhruv Verma
Holy shit, really?
Dhruv Verma me too but idc about the name
# SOMETHINGAMER # I watch it more now
Gorgeous. New sub. ♥
where do you get your t shirts?
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
where does the host get his shirts?
How fitting, I was just studying this topic for my A-levels 🤔😄
Love the shirt ^^
Need deeper dive. What tells the glu to activate?
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.
