A way better definition in under 5 minutes than my school could teach in four years. Dear lord our bodies are amazing.

I think it's important to note that the Sodium/Potasium pumps are working constantly and don't just turn on. They're used to maintain the concentration gradient by pumping out 3Na molecules for every 2K molecules pumped in.

I WANT TO SEE AN ENTIRE NEUROSCIENCE COURSE LIKE THIS.

And basically all of this happens in a fraction of a fraction of a second, maybe even faster. I’m speechless.

Thanks a ton for the polarisation process :) I literally had been banging my head around for straight 4 hours.

Thanks TED! Your TedEds will find their way to my classroom to wake up high school seniors every now and again!

Perfect review of the action potential of a neuron. I really did enjoy this. It made me remember everything I learned from class too.

That was a great explanation of nerves and neurons. Thanks for showing.

I'm glad to have learned this in school. I love biology, too.

Finally! I found an informative video👏🏻👍🏻

Well, that cleared some stuff up. . . Here I was thinking that ion pumps operated when the nerve fired, not to exert the work of rebounding the nerve back to its resting state. But the more I think about it, the more sense that makes.

these videos make me feel more smart

this is amazing..! do you think this complexity can come from the result of probability..?

Very interesting. I would be very interested to see what the nerves are during during a shingles outbreak and how to bring them back into balance/health. Also, the volume seemed fairly low on this video. Thanks!

great info, thank you.

Conventionally, animations are made after the voice recording... so it is very possible that it was a deaf animator instead.
