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.

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.

So hard thinking of brain requires more glucose. i finally understand why 'L' from death note eats alot of sugar. Thanks seeker

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.

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.

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.

2:30 sounds like the sound effects in zoo tycoon lol

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.

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.

Trace, YOU ROCK!!

So now I know why I get hungry so fast when I think a lot lol

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.

That's amazing! Hi from Brazil

awesome, I love things about how brain functions

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!

where do you get your t shirts?

So where exactly is glucose present? Is it present all over the brain so that Glut4 can take it up whenever it needs it?

How fitting, I was just studying this topic for my A-levels 🤔😄

Gorgeous. New sub. ♥

Absolutely correct

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.

what about people with insulin resistance or diabetes? how does this affect their brains on sugar?

hi, how about publishing new articles about the mitochondria uses fat instead of carbs? about ketosis? that really more up to date!

Now i wonder, whats left of the glucose after the cell "burns" it. You cant just vaporize stuff, it must be converted to something right? (Since ions do provide the energy, it is not that)

@yakarotsennin3115

Жыл бұрын

Cells convert Glucose into various intermediates that are involved in Glycolysis. These intermediates will lose a couple carbon atoms as CO2 as they are rearranged further as intermediates in the Citric Acid Cycle. Intermediates in the CTC donate high energy electrons to electron carriers. In the Mitochondria, these electron carriers provide electrons to the Electron Transport Chain. This ETC powers the creation of a proton gradient in the inner membrane space of the Mitochondria. The movement of protons powers the production of ATP from ADP.

How much glucose would I need to create 30g coming from my legs exclusively?

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.

@heath3546

@yakarotsennin3115

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

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.
