What is Action Potential?

[@andrehedlund7762]

You're awesome! More people should watch your videos. I'll help spread the word. Thanks for the great explanation!

this reminds me of Bill Nye...very good video

[@Speedy5310]

2:26 This is not entirely correct. Quickly (and simply), the neuron is permeable mainly to Na+ at this point and EqNa ~ +40mV (net Na+ going in and out are equal), hence why the peak of the AP is around here and no more depolarization (as well as delayed v-gated K+ opening). You got this correct in your other videos about ion driving forces (diffusion and electrostatic), but you just forgot to apply it here. Overall, great work!

+Speedy5310 Thanks for the feedback! I'm glad that you caught our mistake - we're still working on how to explain these concepts concisely and clearly, and it's great to have community input to help us improve our work. We'll talk about this as a team and figure out how we can add a note to clarify this for future viewers!

Best explanation for action potential I've seen! Thank you so much for this vid

hi can action potential method can heal mild annular tear

[@shivanandbinoj524]

Heyyy.. The Video was so simple to understand , and it was interesting and could reach the average Joe too ,since u spoke just like a commoner , without using much of technical jarguns, so that everyone could understand....... Btw u look ravishing!!!

[@Sammy-eb7me]

THANK YOU THANK YOU THANK YOU. I suck at science this helped me sm

[@neurotransmissions]

Hey, you gotta start somewhere! Glad you found it useful! 😄

[@sujatajain7997]

Thank you didi u just nailed it. I just enjoyed a lot watching this video and I loved it. Please keep making videos on such topics.

[@ChiNguyen-mg9pr]

Thankyou for making this subject interesting!

1:21 😂 awesome movie it is!!

[@shadyws310]

thanks you explained it better than my prof.. lol

[@jodyemanuel6371]

Great Video!! and thanks for the links

[@neurotransmissions]

You bet! Thanks for watching!

[@issackgabow4223]

Awesome

[@nicolaiveliki1409]

I actually wonder how the neuron determines where to send the signal. Or does it just attempt to activate all neurons it's connected to?

[@emilybates8489]

Thanks, this is great!

[@neurotransmissions]

You bet, Emily!

[@GabrielaSanchez-xx1gw]

love your lectures!

[@Nixie_536]

Merci 🌠 😊🙏

[@manjulaanil6262]

wht is polarization in neuron???

[@ksrinsky]

Perhaps I'm stupid here. I'm having issue with the last video, trying to comprehend what seems to me to be an inconsistency: you said that potassium and sodium were postively charged, and cloride was negatively charged. Then (I thought) that the inside was positively charged (containing primarily potassium) yet you said it's negatively charged. By my logic the only way to have one side negatively charged is a surplus of calcium. How is my logic failing me? What am I missing?

[@ksrinsky]

correction calcium=cloride

[@Jess-cv5nu]

There are large negatively charged protein molecules inside the cell that maintain the negative charge and help keep chloride outside of the cell at resting potential.

[@farahhanumnoor6235]

Thank you!!!

[@neurotransmissions]

+Farah Hanum No problem!

[@mirshabnam1828]

Bad ass ! Ur teaching skills r js supa fab n supr cool 👍

[@Panda74gofaster]

its hard to learn, you are so adorable... I need to focus... lord help me.... Great lecture, it helps, keep doing what you are doing... Be safe.

[@112abhisheknare2]

Wow

[@rockanderson1823]

Wish you were my teacher. Smart and pretty.

Whoever invented this neuron sht has nothing better to do with their life. Now I got to worry about how messages are pass through my brain in order to pass this psychology class. So annoying
