@@PsychExplained AGREE! I am doing a degree in neuroscience and can't understand a thing the professor is talking about. Very grateful for your videos!
OMG SALTY BANANA!!!!!!!!!!!!!!!!!!!!!!!!!! I literally constantly forget what’s high on the inside and what’s high on the outside. Now I’ll never forget. Thank you!
🧂🍌 Na+ K+ ATPase love your videos ❤ Dr. Kushner 🥼👩🏽🔬 this was so easy to understand because you draw it and break it down. Great graphics Salty Banana 🧂🍌 pouring salt all over the banana and remember -70 to +55 then resting
I needed to draw a cartoon with the steps and your video made the HW easy! Easy steps great drawing and perfect memory techniques. Met and exceeds all expectations
After years of reading AP over and and over, watching multiple videos, making notes for 1000th time.. this video finally taught AP without having to mug up😭😭🙌🏼🙌🏼
Amazing Teacher, honestly not only did I learn more about Neurons but I also learned how to teach in a more clear fashion by watching how you explain things
OMG!!! thanks very much for this! I have never commented on any video on RUclips....but i think this video triggers me, it's well explained. THANK AGAIN!!
I just finished watching the video, I haven't even opened my notes yet because this guy deserves this comment. BEST video ever, your page is my go-to. THANK YOU for explaining it so easily, my 1 hour and 15 minute lecture didn't explain it as well as your 12 minutes did!!
Yo I don't know if you still make videos but keep it up! I'm taking AP Psychology right now and you have hands down the clearest and most thorough explanations I have seen yet. It hits that sweet spot between simple to understand and complex enough to contain all necessary detail. Thank you and I would really appreciate if you were to post more.
Appreciate the kind words! It may surprise you but I teach high school AP Psychology. These videos are for you, and helping you earn that 5! Many more to come.
I'm a first year med student and this video helped me a lot!! Thank you for explaining very clearly. The banana reference is very clever. Now, I'll never forget the arrangement of ions during resting potential!
Thank you for the very well put explanation. The only thing, however, you didn't mention was the sodium-potassium pump, which is what allows the neuron to return to the resting stage after being hyperpolarized!
Your energy is everything and so are your teaching skills! God bless you! Thanks a lot. Doing my nursing degree and needed to understand this well!! Everything you said helped a lot🙏🏾💕
I love the way that you explain things ! a person who even dose not have science background can totally understand it and that is amazing ! keep spoiling us with your videos
Again thanks so much for the detailed yet not overcomplicated explanations. The visuals really help me relate math and science together something I normally struggle with a lot.
Fantastique! = +-+-+-+-+-+- ... I recently learned that due to a violent upbringing I have premature myelination and four other premature stuff that went on at a microscopic level within me. I was left with axons looking as if they were pumped up on steroids due to development adaptation. This vid has just given the nitty gritty to my external potential. Look out bad world, the Hulk lives. THANK YOU Doc.
I went over this topic in my psychology book over and over and over and jus couldn't get it. 12minutes after watching this and I finally understood!! thank you so much
Your a life saver i have a test tomorrow for AP Psyche about action potential and i didnt understand anything about it when my teacher was reviewing notes 😅 thank you
I'm a first year uni student and I've been looking for videos explaining this concept. This was perfect and really easy to grasp, you just gained a new subscriber. thank you
You are teaching me also English! Keep going men. Please more on statistics (null hypothesis, regressions) and physiology (muscle function, muscle damage).
This makes so much more sense now! Thank you! I am taking psychopharmacology and sometimes the readings just blur together. The visuals and concepts used (salty banana and toilet refractory phase) just helps tremendously! I am now a forever subscriber!! Thank you- I will watch all your videos
Thanks, good explination! But what happens afterward because this time all the K+ is outside and Na+ is inside. The normal position was the opposite (K+ were inside and Na+ were outside).
Potassium channels open in response to depolarization, allowing potassium ions to move out of the cell down their concentration gradient. This efflux of potassium ions helps restore the negative charge inside the cell. Sodium channels that opened during depolarization begin to close, reducing the influx of sodium ions into the cell. This decreases the positive charge inside the cell. As a result of these processes, the ion gradients across the cell membrane gradually return to their resting state, with potassium ions predominantly inside the cell and sodium ions predominantly outside. This restoration of ion gradients allows the neuron to prepare for subsequent action potentials and maintain its resting membrane potential.
The resting membrane potential of approximately -70 millivolts (mV) inside a neuron at rest is primarily due to the differential distribution of ions across the cell membrane, particularly potassium (K+) and sodium (Na+), as well as the selective permeability of the membrane to these ions.
Sir yor explanation of the action potential was very good, but you did not explain how the amount of sodium on the outside and potassium on the inside return to normal.
Repolarization - brings the cell back to resting potential. The inactivation gates of the sodium channels close, stopping the inward rush of positive ions. At the same time, the potassium channels open.
Many thanks for your really clear explanation. I just have a question. When the neuron is hyperpolaraized and is full of Na+ ions and has lost K+ ions, how does it get back to the resting potential? Do gates open to eject the Na+ ions and allow K+ ions back in or is the cell wall leaky and just allows the Na+ ions to escape gradually and allow K+ ions back in?
Sir you explained really well but Kindly tell me why chloride ions didn't play that much role in action potential though they are also present in this process? kindly Explain.
this helped a lot thank you so much! I do have one question though. In my lecture we discussed about NA/K pumps being involved as well. Are the channel gates considered those NA/K pumps? or are they something else and do what do they help with?
Whatt a great explanation finally i understand action potential just one question that in the end after hyperpolarisation do the sodium ions also go back out of the neuron??
NOTE this error: at time-stamp 9.26 he said that the "potassium voltage-gated ion channels are going to open up, and this is going to cause these positively charged sodium ions are going to rush outside of the cell" However, it's K+ that rushes out through the potassium voltage-gated chanels NOT Na+.

wow you deserve the Nobel prize for most clear understanding of an action potential.
Much appreciated 🏆 😀

Literally this!! Summed up everything that a 3 hour lecture confused 😊
OMG SALTY BANANA!!!!!!!!!!!!!!!!!!!!!!!!!! I literally constantly forget what’s high on the inside and what’s high on the outside. Now I’ll never forget. Thank you!
It’s all about the mnemonics 😊
@PsychExplained You're doing the LLOYDS work! Keep it up! Looking forward to watching more videos.

In physio psychology introductory class best explanation I have ever seen
❤😅right! Wish he was my profe!!!👨🏽🔬🥼
This is THE best explanation I've seen of this concept on youtube omg
Thank you 😊
This man was MADE to teach, God bless you
THE BEST, most comprehensible explanation I've seen of this process. My immense gratitude.

I love you dude. saved my life
Love you too 😉
Why is the voltage at -70 inside at the start? If potassium is positive, what else is in the neuron that's so negative? Great video btw, thank you!
The resting membrane potential of approximately -70 millivolts (mV) inside a neuron at rest is primarily due to the differential distribution of ions across the cell membrane, particularly potassium (K+) and sodium (Na+), as well as the selective permeability of the membrane to these ions.
this was so helpful it’s been 3 weeks and i still didn’t understand

Sir you explained really well but Kindly tell me why chloride ions didn't play that much role in action potential though they are also present in this process? kindly Explain.
They play a major role at the synaptic bulb (axon terminal). I will touch on this more in my next video on neural transmission ⚡️⚡️⚡️⚡️⚡️
Easy to understand - Great
Glad you think so!
Please make videos on sensation and perception.
Best of the best I know this process now thank you so much🙏🙏🙏
