Here’s a thought: What IS a thought? I know it involves my brain, and my brain is made of neurons. And my brain’s neurons are listening to other neurons all over my body. But how do those neurons actually work? Maybe you’ve heard that it involves electricity, but does that mean you’ve got little zaps and lightning bolts running through your veins like Pikachu? Don’t worry, I’m here to set you straight on what a neuron is, what an action potential is, and how fast your nervous system really communicates.

The most shocking thing in this video is I just learned that roaches can regrow legs..
just googled it, they take 3-5 months to fully grow back. Their life span is 4-5 months so technically he wasnt lying but it will likely die before its grows back fully. dont worry, nobody gaf about a roach no matter how bad you torture it, i could upload a 1 hr cockroach torture session and it probly wont get taken down.

Funny, I thought that this video was pretty useless for me. There were a lot of filler sidetracking stories, and then just a tiny bit of fairly meaningless, old fashioned lecturing about molecules moving around, all of which left me no more informed than I was before. As someone else said, the most impressive thing I learned in this video is that cockroaches can regrow their legs. Except that apparently adult cockroaches like this one do not. So the production crew seems to have told some lies. (Also, I learned that TH-cam apparently allows animal torture, which I thought was against the TOS.)
Too true.

@@manumalus You are quite correct. However, as always, the result obtained is far more a function of the diligence and intelligence of the student than the name of the college.

We are most certainly living in the era of “information overload.”
I'm in an automatic controls class for my electrical engineering degree and seeing the voltage vs time of the neurons using electrical potential was awesome. Then I noticed it was perfectly damped to get back to the resting state, not over-damped or under-damped, but I guess maybe that could explain certain neurodivergent behaviors as well on the macro scale, along with many other things.
11:19: So that settles it. Brains are digital.
No matter how much is explained or empirically verified about the chemistry and circuitry of neurons, I still find it so hard to believe a large, complex enough gathering of them allows them to be aware of themselves. Fascinating.
What gets more interesting is the self aware part thinks its in charge and making the decisions but we are increasingly finding it doesn't. It justifies them after the fact in many cases. The part of you that thinks of itself as you is very much more a passenger than a driver. We seem to be able to make some complex decision making without actually needing self awareness.

Hello fellow kids
5:48 in case you're curious,here's what people thought before that:
Three different theories of nerve function were debated as the seventeenth century drew to a close. First, many scientists still adhered to the notion of spirits running through the hollow nerves to contract the muscles or convey impressions to the
brain. This was an ancient idea, but Rene Descartes, among others, embraced it.
A second theory held that the nerves secrete droplets of fluid onto the muscles to
activate them. Thomas Willis, for example, thought that when nerve fluids mixed
with blood and fermented, they could cause minute "explosions," which would result in muscular contractions.
The third theory was the idea that the nerves transmit information by vibration.
This idea found its champion in Sir Isaac Newton, who attributed color perception
to different waves of light causing corresponding vibration patterns in the nerves
from the eye to the brain.
Did Newton think of light as waves? I thought he followed the corpuscular theory of light as little particles
Honestly theory 2 is kind of awesome. Muscle explosions!
@@Guru_1092 muscle explosion sound nice to you?
@@mahadevprasanth1697 he did believe light were particles rather than just waves.

12:47 confirmed that Patrick Star is smarter than Spongebob.
Myelin is actually what determines our skill in any given thing. The more you use that neuron chain, the more myelin it grows. This myelin speeds up the neuron chain, like you mentioned, and the more myelin we have, the better we are at that skill. Give the Talent Code a read, it talks a lot about that sort of stuff.
Is it true for all kinds of memories?
@@son5051 Yep, most skills can be improved with more myelin. Albert Einstein's brain was actually shown to have a higher concentration of myelin all around, than most people, which is probably why he was so smart.
@@infiniti2011 yet, his memory was pretty bad.
@@thesavantart8480 Yeah, that's absolutely true. But that was more for everyday practical knowledge. For physics, mathematics, and data, absolutely not. People on the spectrum may have terrible memory in some places, yet unlimited recall in others. Einstein was believed to have Aspergers and ADHD, so that might be the cause of those issues.
No, it's not that easy.
A lot of things change around a Neuron that is fired frequently. For example, the amount of tunnel and pump proteins around the axon, the amount of synapses, or the amount of molecules released into the synapse per unit of current all may increase depending on the nerve cell at hand. Of course, quicker signal transfer through myelin increase helps, too, but it's not a one explanation fits all.
Out of curiosity I’ve asked my teacher this a few times but never really got his explanation. So this video is a godsend thanks 😊

As a physical therapist working with a lot of patients in pain, I would just like to point out/correct a statement that you made about pain...we don't have "pain nerves" or "pain sensors" etc. The correct terminology is nociceptors and nociception. It may seem like a small semantical thing, but pain is a construct of the brain and nociception is only one part of the picture of the pain experience, and that makes using the correct terminology so important!

In electricity, the electrons actually wobble in place, not exchange. Its the field produced from the wobbling electrons that produces the charge. The exchange is a common error that has been recently amended.

The brain generates its own electricity through a process called "neuronal firing." Neurons, the basic building blocks of the brain, communicate with each other by sending electrical signals. These signals, known as action potentials, travel along the neurons' axons, which are long, slender projections. When these signals reach the end of an axon, they trigger the release of chemical messengers called neurotransmitters, which then stimulate or inhibit other neurons, continuing the electrical activity throughout the brain. This complex network of electrical signals is what allows the brain to process information, control bodily functions, and produce thoughts and emotions.
Wow, I learned most of it at school last year but I wish it had been explained in such a great way and so detailed.

I hope you see this, Dr. Joe. This gives more information for a different purpose, and I wanted to share this with you.
We love watching this science kind of stuff. This one has a different significance to me, though. It's interesting to watch all the way through and I recommend you do. It's done in a very easy to understand way (he's very good that way).
But around 17:30 he talks about the myelin which is stuff that surrounds nerves. Apparently, it helps the information travel down a nerve faster.
The reason it gave me an "Aha!" moment is that in MS, the immune system attacks the myelin and destroys it. Having this explained the way it is helps me realize that one of the things happening is that the "turbo boost" the myelin gives nerves is being destroyed in MS suffers, ... and thus, making the nerves communicate slower than they normally would.
This is why I love these shows. They can be helpful in more ways than just some fun knowledge.
This channel is absolutely spectacular... Thank you SO much!!

It’s always been incredible to me how many parts of the human body work on electricity and voltage (something we usually associate with computers, wires, etc.)

Galvani is how "galvanizing" got its name, isn't he? :O

When he dabbed I cried.
"Come out. It's gonna be fun. Come do some science with us!"
Rips off the little guy's leg.
"Don't worry. It'll grow back."
Except it won't because the roach is fully mature and won't moult again.
Also the ice water didn't sedate the roach. It agonised and paralysed the roach, but it didn't put it to sleep. It might have drowned the roach, though. Insects have book lungs and cannot hold their breaths like humans can (not that we can hold our breath while paralysed or asleep either.) I know crickets can die in mere seconds in water so shallow they can literally wade in it. So maybe the roach didn't feel the loss of its leg? Maybe it was already dead from drowning...

The flash: GAS GAS GAS!
Recognizing and being impressed that the nervous system conducts and operates with electricity should be the starting point to develop intelligence in more people . Not just scientific intelligence (there's plenty of that) but social, personal intelligence, which is not only virtually non-existent, but crosses past zero into the negative measurements, i.e., stupidity. An idea is a thought, but a thought only exists as an action, that is to say, it exists as a flow or pattern of electricity, and yet people treat ideas as property, as if thoughts are things one owns and must defend. Once anyone voices an idea, not only does that very act of communication is giving it away to others, but the reception of that thought is immediately met with the entire nexus plexus of another's mind and therefore is modified through interpretation. And yet people hold onto their ideas as if ideas are fixed, permanent, and have validity by resisting temporal change.
I feel like I don't understand what you said and yet I also understand it somehow but i *think* that's an example of exactly what you said if I'm not mistaken
Just realized how truly repellant Pickle Rick would have been in truth -- that twitching leg is horrifying 😳
Question: "If you grow a light bulb in your garden, does it grow into a power plant?"
Edit: "Also, if you move around a power plant, does that make you a power ranger?"

If you wander around in power plants, does that make you power ranger?
Lol
