  • I feel like it was a little like Jimmy Neutron except it didn't go through his ear :D

  • love the video man

  • That's what just happened in our brain as we were watching. Isn't it cool? ;)

  • Very cool and accurate display of how neurons fire, props!!:) A++

  • can anyone tell me what's happening @ 00:23? what are those circles with a plus shape in it? is it protons or something O.o

  • @manhidnatao I think it is illustrating conduction down the neurone, and how there is a net movement of positive charge into the axon as the action potential is propogated. This is because sodium influx (sodium ions carry a single positive charge) is greater than potassium efflux ( potassium ions are positive also). It is also important to note that it is illustrating an unmyelinated neurone, as it occurs across the entire length of the axon. Hope that helps :) x

  • @newquaysurfer234 thanks. :D

  • @manhidnatao I think it's sodium influx and then the bouncing back represents the potassium efflux...that's what I made it out to be.

  • I was waiting for an action potential to trigger vesicle release but didn't think I saw it. Overall, the animation is of high quality.

  • I LOVE THIS ATLAS!!!

  • @Brocaserter did you check out the new one from this year? whoa... so much more detailed pics. Sadly, not on the brain section. :) All the other organs in excruciating detail, but not the most important one. It bugs me.

  • @alxivanov No, I didn't check it out ;) Yes, very sad that there isn't one on the brain section... I have only the brain atlas, of course other organs are great, but the brain is the most important one :)

  • WHERE ARE THE NODES OF RANVIER?

  • Sounds effects makes me more permeable to understanding!! :p

  • @alxivanov where can I get a copy of the illustrated medical atlas DVD?

  • I love this animation.

  • why is there no myelin?

  • Wonderful animation to illustrate how human brain works.

  • can anyone answer this:

    are the + signs Sodium ions? and

    Neurotransmitters binds with the receptors of the post synaptic cells... that allows Sodium ions to get in the post synaptic cells...is that required for the next action potential?

  • @atph120890 no the + signs just means positively charged ions. when an action potential occurs, the positively charged ions rush into the axon, depolarizing it. after the action potential, the positively charged ions go back outside the axon, which is their normal place.

  • @naynay1024 wrong, they ARE sodium and only sodium ions. additionally this video does not accurately depict axonical transmission or synaptic transfer, it does not show myelination or the nodes of ranvier. and most synaptical vessicles do not have there own ion channles. they simply pass into the lipid bylare because they are made of the same material. 

  • @atph120890 required? no, its the most likely way it happens but potassium can also do it, or a seizure, or some other things. look for an animation of the opening and closing of voltage-activated sodium and potassium channels during the three phases of the action potential. that is the mechanism of how a nuron fires.

  • Poor understanding of NT release and postsynaptic action

  • wooooshhh

  • That was awesome, both the visuals and the sound. Great stuff!

  • LOVED IT! Looking for something to help me on my exam tomorrow and this did it!!!! Aaaaah yay

  • tis is a very coolllll video hey keep it up.

  • Yeah this video it awsome I need to find one that explains what is actually going on and everything but this helps thanks, refreshing nontutorial style :)

  • Very good! The visuals are better in my opinion, but using sounds too adds to the feeling that something is actually going on. A small, unobtrusive dialog box to state what is being depicted would be helpful for someone like me who doesn't entirely understand what was happening when the middle segment of the axon was zoomed in on. I think it was showing the polarity changing as the action potential traveled through it, but I'm not sure. Great video

  • short interesting clear visual demonstration. thanks

  • very cool.

  • Should be two versions, 1 as is, 2 with narrative for self taught individuals like my self.

  • Ok tell me Who is obama and osama?

    who was bush? who was saddam? Who is lindsay lohan? What was 9/11? what is fifa world cup 2010? etc etc.. The world after 1970s. That is . The world programed in the computer, go to north pole or go in mongolia deseart, U will find programed movement and subconscious blocks.

    I am Mind control. Its proven

  • These electric fires or pulses is nothing else but what you call your self, I am, being, consciousness, etc. But 90 percent of ur mind is subconscious mind, Which make you feel like what u feel.

    Now, If I have a nano device, that can receive and transfer electric pulse information, I can hack your all neurons, your nervous system. I can change you like rubber, Because You dont have any power over your subconscious Mind. And I will control whole world humans, creatures with supercomputer program

  • or programming, not even that, I can make imagination, thinking, calculation etc etc. in your brain with my computer, and You will feel your self.

    Thus, I can control whole world and Do whatever I can, from a human baby to adult I can create your whole being with just flick of my computer.

    So, I am everything that exists in your mind, and out side - that what you define. And I will control you all

  • yes sound cool

  • That was really helpful :) thanks!

  • Amazing effects both from the visual and the audio. They dually-complement each other for performance. It targets both visual and audible learners, making it an effective method. The instructor's lecture will apply the final touch. This was like watching a movie in a theatre. I actually wanted to see more. Really, this is amazing. Do you have any videos on the cardiovascular system?

  • this 59 second video helped me understand the synapse which i couldnt understand for the past one month.thanks alot! and yeah the sound is very nice.had the''harry potter'' feel...

  • show us wat weed does .... block those fukin holes that are stealing those small marbles.. let them live freely! muahaha... just kidding :D

  • Brimston is not quite accurate himself. The potassium (K+) contribution to the spike is NOT crucial, though it is often presented this way: the mammalian node of Ranvier does not have voltage-dependent K channels; what causes the spike to come back is just the inactivation of Na channels. However he is correct that the depiction of synaptic transmission is rather inadequate and even misleading: no clear exocytosis or transmitter release.

  • This is a really cool-looking video, but it's got some inaccuracies. The action potential traveling down the axon really should show both the Na+ and K+ since they're both crucial to the propagation. Plus, at the synapse, it would be nice to show the proper vesicle cycle, as well as maybe the Ca2+ signaling.

  • visuals are nice, the sound does not match the visuals imho. perhaps youtube.com/watch?v=7MqbIagmLa­0 would help :-)

  • I wish you success in your studies have been nice to be appreciated

    mcmajans.com

  • Question: Is the Positive charge on the Axon found inside the Myelin? I just noticed that there is no Myelin in the video.

  • I wish the ACh transfer through exocytosis would be detailed a bit more... it took a bit of squinting to see that they did actually depict it... the angle it was shown was a bit weird and blocked all the action going on. :(

  • @AznKenshin Me too, I was thinking the vessicle opeing up and realing the neurotransmitters ought to have their own sound....dripping?

  • How does that old Foreigner song go? ... I wanna know what love is, I want you to show me...

    Well, I'd say that this video does a pretty good job of that - that is to say - a good job of showing what love is.

  • tHANKS---YOUR WORK IS POWERFUL.

  • this is great.helped me a lot.

  • excelent animation!!!

  • I like both

  • I really like the fact that there is NOT a narrator, because that way when I talk about it with a class, I can use the language that the assigned textbook uses, and not have to "re-interpret" what might be a different vocabulary set into the language of the resource at hand.

    Showed this to a class yesterday, asked, "do you like the sound effects?" One student said, "neurons don't make whooshing sounds." I replied, yeah, like the spaceships in star wars.

  • @TheDoubleucee Or maybe the neurons DO make sound effects, it's just that we're not close enough to hear them.. ;) like the proverbial tree in the forest.

  • @alxivanov They actually DO make those sounds. Idk how but they proved it to be true that the nurons make that sound.

  • @TheDoubleucee you could just otherwise turn the volume off

  • Nice CG

  • awesome feel to this ...

  • THE NEUROLOGICAL INNER SPACE STATIONS ALIEN UNIVERSE WITH IN. VERY WELL DONE SVZERPCADT.

  • The animation is far superior to anything I was exposed to in college!! The animations and colors are fantastic.

  • Fabulous, I love it. P.S. God has nothing to do with this.

  • Very Nice!

  • Comment removed

  • Great animation and video. I would have to agree with the other comments stating that narration would be welcome. If someone is looking up this video, it is likely needed as a learning tool. Narration or even pop-up text boxes would be helpful.

  • 2+**

  • @newhopecalgary How can God not fit into this? Look at the complexity, the perfection of the design! There's no way that we're an accident.

  • @newhopecalgary The way God, or even consciousness itself figs into all this, is what some psychologists call the Big Problem. That's in contrast to the Little Problem, which (someone can correct me if I'm wrong) is about how the brain works as a whole from a rational, and not a spiritual point of view. From what I've read (e.g. Pinker) we're not even close to solving the Little Problem, not to mention the Big one. So, let's revisit your question.. say, a hundred years from now?

  • @alxivanov Thanks, sounds like something my grandchildrens, children can figure out :)

  • @alxivanov Very well said! Let's leave "God" out of synaptic integration and focus on the molecular neurobiology at hand.

  • @alxivanov

    From another perspective I'd like to point why God and our physiology go hand in hand. Our bodies are simply amazing! More efficient, more intricate, more special then anything humans can come up with. I'd say we would be blinding ourselves to say we got here through an evolutionary process. Darwin had no clue about this stuff when he was composing his theories. And it is illogical to say that something so complex as ourselves happened on unguidedly on accident.

  • @becklei88 hehe thats so cute

  • @newhopecalgary i think thats a question a lot of people have asked themselves, certainly when you can appreciate the sheer complexity of it all. Personally, studying molecular neurobiology has made me an atheist. At first you think that something that complex could never arise spontaneously, then when u start playing around in a lab you can see how there is no rhyme and reason to the way biology works. There in so no doubt in my mind that no 'guy in a cloud' snapped his fingers and created us

  • @newhopecalgary why do you need God, anyway?

  • @perplexedmoth

    can't speak for others, changed my life,depression,suicide, not gone but gives me something to live for, YMMV.

    Keith

  • @newhopecalgary

    Exactly why you created him in your head. Self defense mechanism.

  • @DrShakesBALLIN The fact that humans are not only made up of biomolecules, but we're also FUNCTIONAL beings points to intelligent design.

    C'mon, we're billions of times more complex than any robot anybody has, or will invent, and yet you deny that we were created?

    You're right, it's a self-defence mechanism. haha

  • @fandanstan

    I can't tell if you're agreeing or disagreeing with me. :(

  • @DrShakesBALLIN *sigh*

    You said newhopecalgary created God in his head.

    I said there's more evidence of intelligent design than not ... unless "Exactly why you created him in your head" means something else...

    :3

  • @fandanstan

    Aww. Cute cat face :3

    Anyways, can you imagine life where our creation is unexplained? Can you imagine life where we're dependent on ourselves and others to do what is needed rather than a deity? Can you imagine life where you don't know where we go when we die? Can you imagine a life where there are millions of opposing believers all around you? It.. It feels like living in a world, where Scientology is the master religion. Would you believe it, because its there?

  • @DrShakesBALLIN You haven't really added to this conversation besides speaking a bunch of mumbo jumbo. 

  • @fandanstan

    Yeah I know. What difference does it make though. You'll never convince us, we'll never convince you. Tried to go with something new. Bleh.

  • @DrShakesBALLIN If logic doesn't convince you, then you are truly a lost soul.

    I hope you use your head one day. Good day sir/ma'am.

  • @fandanstan

    If you're claiming to use logic then you wouldn't be a theist. I can say the same for you, hope you wake up one of these days. Best of wishes ~

  • @fandanstan what in the hell is a biomolecule?

  • Excellent buts needs a narrator............

  • at the end, what are those relatively big blue things going into the cell?

  • @Anthonychan4444 Ca+ I think.

  • @Anthonychan4444 ions -- can be Na+ too

  • Very cool. I'm learning about this in psych 101.

  • Visuals and sound are both awesome but the sound is top flight!

  • would be helpful to have a narration.

  • great video... thanks

  • like the visuals

  • Like the visual!

    Nice effects!

  • Visuals are amazing!! 

  • I like this.

  • My lecturer was talking us through the video as it was playing, it made the whole thing just so impressive.

  • no need for sound!!!!!

  • Saw this in AP Psych a couple of days ago. :]

  • visuals are good sound fx unnecessary. narration would have been much more helpful

  • reminds me of spiderman movie when peter got his power

  • Very good and useful to induce concept to the students

  • one day I'll do that...one day....

  • the anamation was way better 6b/c i have heard the sound in other vids

  • visuals are pretty good... sound fx... kinda suck

  • i was thinking this animation looked familiar. then i looked in the info box and . . . oh! i have that book. lqtm.

  • great dude.. thanks for making this video..

  • The visuals very nice, the sound makes it that more believable....

  • Visuals are great. My students like the sound effects. 

  • this is excellent, but it would have been nice to have the synaptic transmission shown more accurately. the vesicles are docked with the membrane using cytoskeletal fibres: they're poised and ready to pop. when a pulse comes down the neuron, it causes calcium to enter right near the vesicles, which acts as the final switch to get the vesicles to release. more vesicles then dock with the membrane.

  • visuals baby!!!!

  • Sampsonoff, do you actually know what your talking about because you spelled followed wrong. LOL Nice animation...

  • i love the visuals on how nerve impulses move from the body to the axon.

  • Very nicely done, I'm studying this right now and the link was placed in my course ! good job :)

  • hah amazing.... good graphix ......sound ok and kool.

  • WoW !

  • Nice! very nice! compliments!

    

  • cool

  • really nice

  • super like it..wish theres a narrator or something... ehehhe ...

  • @rianflor fuck a narrator

  • i like both. i think the person who commented below is too critical, unless it's going to some science conference it's perfectly fine!

  • Awesome!

  • thanks for loading this

  • cool..

    

  • amazing -- sound and visuals!

  • I like the visuals more than the SFX, but the SFX is pretty bitchin'. I really like the video over all.

  • @mrelectron111 I guess hypothetically anything is possible, but I am not aware of any technology that enables "hacking" into the brain. There may be natural waves or some man made phenomena that effect brain electricity that we are not aware of. Doesn't the MRI scanning process knock the polarity of Hydrogen atoms momentarily out of whack? Maybe the technology could be adjusted to effect Na+ ions, that would effect brain electricity. Who knows.

  • Visuals and sound effects!

  • WOW

  • @alxivanov

    fuck the productive life... if we depressed then we depressed from something, take life changing hallucagens(like LSD,shrooms and I am pretty sure that ketamine can help too) and you will see that you bothered by the dumb way of life that the govermant rapes you into, all this shit that psychatrist give us, are just mind bluring pills, that makes us feel like everything is ok, while its not... think about it, and live for your self, and not for your country.

  • @FimaWWW try to get some pure mdma ("molly" not "e"), methylone, or 2c-e...K and shrooms help but they can only show so much. Can't comment on L personally but I hear it is one of the purer connections. Pot can be a band-aid but is not a solution...don't mix pot with other substances.

  • @mrelectron111

    drugs are "hacks" to our brains,

    on the electricity level, doctors can shock us in the head(cures depresion and calms down the subject) but nothing more(at least for now), I hope the humanity will be erased before humans will understand how to control our minds and read our thoughts, the technology is not that far from that, I just read in "national geographic" jurnal about robotic hands that can replace missing hands, and its understands our brain signals!!!

  • i love the sound effects!!!!!!!!

  • @mrelectron111 Write a novel about it. ;]

  • @alxiv lol :) actually there are some pretty old open records of studies on rats where they would put a device wired to certain parts of their brain and eventually the scientist were able to control in which direction the rat would move, at first very inaccurately but finding that with time the brain it self would re-wire accommodating itself even more to the input from the chip! lol and theres a lot of very secretive creepy experimenting wt fiber optics and this. who know what they have......

  • Cognition mediates emotion...'Remember' it's corresponding feeling and be emotionally insynch with the emotion of ur choice.

  • Awesome

  • @alxivanov well, that would require first to understand the entire brain and nervous system and each and every neuron, electrical impulse type and chemical transmitter, and every connection in the brain and body, and then developing a system to connect to the brain and central nervous system and translate that info into readable information which is...hard without screwing yourself up...imagine the speed you would need your cpu to run at...better to experiment on simple minded creatures first...

  • so good if there would be someone explaining what really happens.

  • Waaaaaaaaaaw

  • can you explain step by step what is happening in this video?

  • I love 3d animations,I want to learn how to do that for my memoire next year,3ds max here I come!!!!

  • and what were the small blue circles at the very end?

  • neurotransmitters.

  • @iamborghini1 they are Neurotransmitters

  • what were the little bubbles with the plus sign?

  • Na+ entering the neurone.

  • @iamborghini1 I think thats the electrical charge caused by the myelin sheath on the axon

  • Thanks! This makes a little more sense now!

  • great =)

  • this makes it little be more clear to understand the signaling...

  • very good...it helped me a lot to understand the process...thx =)

  • woooooooooooooow

    really goood

  • Great animation. Thanks for uploading it.

  • Love this animation!!! Thanks :-)

  • I love this and I keep coming back to watchi it neuro-physiology is an awesome subject

  • I also have MS so it is a pressing subject ;)

  • nice work , thankyou for posting

  • whats the name of the dvd? it really looks great... but the action at the synapse could be better. the ultra tiny neurotransmitters are very hard to see ^^

  • should have narration on whats happening. would be better explaning.

  • slottuz  just think about it!

  • interesting stuff. Im pursuing a career in molecular biology hopefully working with pharmaceuticals which can help with the daily functioning of individuals.

  • Awsome but i have ocd so to much of this stuff happens

  • moar like this

  • all that shit is happent rigth now on my brain wtf

  • its happening at 1/1000 of a second actually.
