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.
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.
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.
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.
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.
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.
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
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).
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
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.
"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.

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.
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
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?
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
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!
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
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'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.
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!
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!
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.
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.
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.
Also, a nitpick (he is factually wrong, but it's a side issue and he is simplifying things) ... at 2:43 to 2:47 he says that mitochondria burn glucose. But they don't. One molecule of glucose is converted into two molecules of pyruvate during glycolysis, and it is the pyruvate (not glucose) that enters mitochondria.

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)
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?
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.
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.

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.
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.
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.
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.
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! :)
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.
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
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.
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.
isn't it funny that we're using our brains to find out how our brains work lol

That's why spiritual people say you r not even the body and not even the mind👍

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
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.

Hmm, this is food for thought. No, wait. Glucose is food for thought.
LOL ^_^
haha! 😄
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

If your current diet works for you then great. But the science says that your brain would work better on glucose.
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
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?
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.
Brain also functions well with Ketones not only glucose
My brain goes into seizure mode when I eat too much sugar.
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.
That's amazing! Hi from Brazil
Do one create own thoughts or are thoughts already in the brains just one to discover them?
thanks. i like your channel's worthiness
The neurons dont release ions (2:13) which is grabbed by other ions but neurotransmitters, they are not ions.
the mitochondria is the powerhouse of the cell
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!
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.
Thanks for reminded me that once the semester ends so does everything I've learned in psychology/neuroscience, have a like.
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.
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.
nice one, Trace
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
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.
where do you get your t shirts?
This guy is my favorite D News/Seeker host!
When the glucose is brought into the cell by the gluc 4 and the mitochondria breaks it down , are photons released too?
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! :)
energy is the source of limitless power in everything😵
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
So where exactly is glucose present? Is it present all over the brain so that Glut4 can take it up whenever it needs it?
hi, how about publishing new articles about the mitochondria uses fat instead of carbs? about ketosis? that really more up to date!
hey i was looking for a word "opis" well its a kind of emotion and i would like to have some information regarding that.
please help me
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.
Really cool T-shirt!
Great video , thank you
So the underlaying cause is thought. Because if you're not thinking anything those Glut4 things are not moving anywhere?
At the most fundamental level its the movement of charge!
you're just saying same thing that we learn in school nice.. 👏👍
Did you know: The mitochondria is the powerhouse of the cell. *The more you know*
What I learnt this video:
Mitochondria - The power house of the cell.
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.
How much do I need consume sugar before studying ?
how brains work: PLOPP! SWOOSH! mieee...
where does the host get his shirts?
