Neural Impulse 3D Animation

3D animation of a neuron and an action potential. Ion channels in the soma open and allow an increase in the intracellular voltage. Once the voltage reaches a threshold, an action potential is generated, which travels the length of the axon and passes into the terminals. The voltage in the terminals stimulate the release of neurotransmitters which cross the synapse, opening ion channels in dendrites of the post-synaptic neuron and increasing the voltage of the second neuron.

someone explaining it would be nice.

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

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

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!

@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)

@evilestoreo17 true dat

[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. ;)

@Emma09lups

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

[wello532]

sure

[Emma09lups]

i think the real its faster than this

[DarkKnight2037]

WOW!!!

PRONESS!!!

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.
