Neural Impulse 3D Animation

[tigress606]

@starburzt What's going on there is just for explanation - every neuron has thousands (if not millions) of connections to other neurons, or the axons get bundled together into what you know as nerves to go throughout the peripheral nervous system (the rest of your body)

[starburzt]

What's the point of the bottom terminal button if it doesn't reach any dendrites?

[Goldex13]

During the 24 seconds of this video, your neurons have fired approximately 4800 times. In that period of time, the signals could've traveled about 1570000 feet.

I don't know why that's important, but I thought I'd share it anyway. ;)

[wello532]

sure

[Emma09lups]

i think the real its faster than this

[wgfcrafty]

@Emma09lups

Indeed. If electrical pulses through neurons went this speed you would take weeks to react to any stimulus.

[DarkKnight2037]

WOW!!!

PRONESS!!!

[ThePrototype4]

actually the speed of a neural impulse can range from an amazingly slow 2 mph to 200+ mph. it depends on the type of neuron (fiber) and the health of the myelin sheath coating on the axon. you cannot say that neurons do not operate like this because there is a multitude of neuron types in the body. for example, you may imagine a neuron as very small, but most motor neurons (which control muscles) are on the order of several feet long.

hi!

i am doing a neural network project, and in need of a 3d model.

can you help out?

[innerving02]

Thanks so much for the explanation!

[limeburst1]

if this is a thought it is very incorrect thoughts travel very fast alot faster than this

[cbrocks36]

It's not a thought. It's basically the process of neuronal cells communicating and sending commands to other cells. These commands create our ability to move, think, feel, talk, listen, breathe, our hearts to beat, and everything else that makes us human.

[S0rb0]

It's way faster than this, this is just a simulation.

Normally a neural impulse 'travels' with the speed 30-100 metres/second through the neuron.

This means it only takes you fractions of seconds to operate.

[evilestoreo17]

are you retarded? nerve impulses are bioelectric, i.e. they travel the speed electricity does.

if they made a video showing it at real speed you wouldn't be able to see it!

[ChaoticNuke]

@evilestoreo17 true dat

i THINK THIS VIDEO IS NOT HELPFUL. I`m a medical student from egypt. The video is just not complete and details.

[bavly6]

lol from egypt same here :) anyway i think this vid is jsut there to give a visual of the process of transmiting the electrical impulses. To a person who really can't understand it by reading alone this would be helpfull because it shows a senaps as a gap which people might think is not. and it shows how the signal is transferd how ever it's ur oppinion

[mtheoryrules]

This real time for my brain.

[onutza017]

very interesting

[prismacolored]

It's amazing that this (and most processes in our bodies) happens several times in just milliseconds.

[lillie62692]

someone explaining it would be nice.

just annoying that no one is actually explaining whats happening in the background.

[steve552266]

Yes, you're probably right, but look at the comments below for an explanation.

[itshouldbelikethis]

what the hell is this?:S is it a viedo game?:S

[Borfoneusa]

--'

no , that's is explaining the neural impulse .

[itshouldbelikethis]

ok i can see that from the text but i don't know what that means. could have been a game titel ...

[Chowdder]

It's an animation trying to visually explain how nerve cells transmit signals. I'm assuming you haven't taken high school biology courses yet.

[itshouldbelikethis]

hmm no and i don't think i can either... im not good with theory and i loose my consentration wery fast..

+ i am from norway...the country with the suckiest test results in the whole world... our teachers suck most of the parents can't raise their kids, everyone is to spoiled. no body want's to do anything and i am sick of it but i can't do anything about it so here i am stuck thinking Neural Impulse was a sucky game from like 100 years ago..

[marijazza]

No, it's a nerve impulse 3D demonstration. It's purpose is to demonstrate the actual movement of neurons by neuron transmitters.

Hi, I'm jack, what's your disability?

[OMARION80]

i have damaged nerves in my right hand what can i do

[xinghutttrwhoper]

visit your doctor...that's the best thing to do.

[WolfSiepen]

why is the action potential blue on the first, and red on the second neuron? that doesn't make sense to me

[f0xgl0ve]

I think the red is the voltage coming in from neurotransmitters taken in by the dendrites, then, as these move down to the axon hillock, the threshold of the neuron is overcome, and the blue action potential is created, travelling down the axon, and in turn releasing more NTs, which set of the reaction in neuron #2.. :)

[Axon36]

I agree with Wolf...it doesn't have sense. If the red trace is the electrotonic propagation of any EPSP, in an axo-denditric conection like this any AP must to be generated on the dendrita if it reach the voltage threshold. If not, i don't really think than you can have that kind of propagation effect for one synapsis.

[f0xgl0ve]

I guess that's a pretty fair comment if I understand you correctly (You seem to have a deeper knowledge of this than me). I was trying to explain why this may have been done in two colours, but perhaps my knowledge of APs and particularly thresholds is insufficient.. :)

[Axon36]

Don't blame your self...this isn't an easy matter. Your interpretation about the video it was correct on principle. But the use of those colors can be very confuse and distracting. I don't know if the author was trying to represent currents and/or voltage. Is after him clarify that point. All the best.

[steve552266]

Yes, you're right. The two colours represent two different electrical effects: Red is the build up of charge from the ion channels, Blue is the action potential, once the intracellular voltage reaches some threshold. I agree it could be confusing, seeing that they are all ions....

[steve552266]

Further, a single synapse would not initiate enough charge to produce an action potential in the second neuron. In fact, individual neurons may have tens of thousands of synapses working together to encourage action potentials throughout the brain. The important part of the synapse here is that the action potential causes the vesicles to release neurotransmitters into the synaptic cleft, opening ion channels and starting the process over again.

[Axon36]

Thanks Steve. Nice comment and animation. It's more clear now.
