My professor showed us one of your videos during a lecture and I am so glad he did, because your explanations are amazing and are helping me a lot with studying. Thank you!
Thank you so much! I've just listened to multiple videos of yours in a row... You take a complicated topic and break it down clearly and simply, in such an organized manner! Fantastic content! Keep up the great work!
I remember watching your videos for my undergrad finals and here i am again watching them for my masters. Wish we had profs like yourself who explain concepts so well! Thanks for uploading these awesome videos!
I just discovered your channel while taking a first-year psychology course at university. I have already watched several of your videos and they are all so accurate and rich in info, you have no idea how much you've helped me!!
Sir I am a psychology student action potentials is a part of our biological psychology syllabus I am so clear now because of u sir thanks for guidance sir
Really good video. I have however a question: what is the relation between the membrane potential and the gates/channels opening or closing? Meaning, how and why do the gates/channels know when to open up or close in order for a succesful depolarisation, repolarisation, and hyperpolarisation to occur?
The sodium and potassium channels that open and close during the action potential are voltage-gated channels, meaning they open and close in response to changes in membrane potential. For example, sodium channels open at threshold and close when the membrane potential reaches somewhere around +30 to +40 mV. So the flow of ions during the action potential process changes membrane potential and prompts the opening and closing of these channels.
Chloride ions don't play a role in the function of the sodium potassium pump. The actions of the pump help to establish membrane potential, which is both influenced by movement of chloride ions and influences the movement of chloride ions. But the 3:2 ratio of the pump is independent of chloride ion activity.
great video . I'm trying to understand how a segment of the spinal cord becomes "facilitated" or more easily stimulated, and the output of pain goes up. Is this a problem in a part of the brain or is it a chemical issue with sodium, diffusion ? Anything I should specifically search for in the videos to watch? Thank you !
The main subject of the video was action potentials, and it's not necessary to bring in the concept of negatively charged ions to explain action potentials. I'm trying to explain the basics, so to me any unnecessary concept can potentially make things more confusing. I'm not the only one to take this approach, though---plenty of introductory texts explain action potentials without referring to negatively charged ions.
Hello, Thank you for your simply complex videos for neuroscience! I've got a question about how diffusion and electrostatic work. so there are various kinds of pumps. Do electrostatic force and diffusion require energy? or do they flow spontaneously? thankyou!
Another question. Let's take a scenario: I thought of walking, walking requires me to physically move my legs. When I think to decide walking, and before I physically walk, what happens? Do these neurons activate and cause an action potential although I didn't physically move? and then if I moved, the cycle of neurons in action potential would continue until I stopped walking right?

im quitre surprised how much accurate information you can relay in 10 minutes. good work
I'm so happy I've found this channel, can't believe how much information you conveyed in a 10 minutes video!
So fabulous. Better than multiple lectures ...

bro's carrying my grades hard, keep up the good work and thanks for making neurology easy to understand!

I appreciate your
detailed breakdown of action potentials. Very organized and thorough.

Not a word wasted, everything important covered: this is as good a ten-minute interval as any you could possibly spend on the subject.
Thank you for continuing this series of videos, it’s great to review neuroscience and learn more about it!
I knew a bit about this but now I understand it better than ever. I was fascinated and you explained it extremely clearly.
I'm just 4 minutes into this video and you've already cleared up days of confusion. Thank you so much!! You are the GOAT👌
I am planing to study neuro-science next year, and I was looking for some videos about this topic. I am glad you made a channel
Thanks you're an angel in human form!
more clear than university thank you
Thanks!
Brilliantly explained, thank you SO much!
Why couldn’t my prof just say this instead of making me watch 10 recordings
yeah i feel like some professors just make concepts more of a pain to learn on purpose lol
Vuz your prof is indoctrinated. Hopefully the answers to the test arent equality and diversity 😂
@@MoreTrenMoreMen69this is so true
Thank you so much, I've been struggling to understand how neurons work for about 3 weeks now and I finally understand.
Great video, it presents with a clear explanation the essential information about the action potential. Thank you!
Great video! Saved me the day before my diploma!
Sir I am a psychology student action potentials is a part of our biological psychology syllabus I am so clear now because of u sir thanks for guidance sir
Beautiful explanation and diagrams
Bruh just did my 5 hours lecture in 10 mins 😩
This explanation is amazing. Thank you so much.
Gracias a tí, por hacer este magnífico video.
Thank you so much sir for this wonderful explanation!
I am in class 11 in india and the video was very usefull. Thank you sir
Thanks. I use your vids in my behavioral neuroscience undergraduate class.
That’s great to hear! I’m glad they’re useful!
Thank you very much sir for great concept learning 🙏
perfect explanation! Thank you so much! It is so clear now😍
Awesome video, love the content. I first found you from the Schizophrenia video, always excited when I see another video posted.
Thank you I appreciate the support!

@@neurochallenged thank you very much for your response!
Wow… you are the best❤❤❤
Very nicely explained. I have one question: where do the chloride ions (-1) fit into the 3:2 ratio of potassium and sodium?
Chloride ions don't play a role in the function of the sodium potassium pump. The actions of the pump help to establish membrane potential, which is both influenced by movement of chloride ions and influences the movement of chloride ions. But the 3:2 ratio of the pump is independent of chloride ion activity.
@@neurochallenged Okay, so there isn't any bond potential or attraction from the Cl- ions? Do they just exist inside and outside the neurons?
I think my professor would love that t-shirt
Does charge travels faster or slower in the myelinated regions?
Amazing video
Thanks!

Most excellent!
thank you so much for this!
Question is what effect does dopamine inhibitors have on action potenyial reduce i think irreversably?
HI thankyou so much for the vidoe could understand it reALLY well can you provide notes also for this
Where did you get the t shirt , thx
My wife made it for me 😊
@@neurochallenged love it ,great content, have a great day Graeme.
Thank you for lecture
How and due to what is a negative charge formed inside the cell? Not a single word is said about chlorine anions.
Where did you get your shirt from
I sell it in my store! neurochallenged.myshopify.com/products/equation-t-shirt
Why is there no mention at all of negatively charged ions? That is confusing. Otherwise, great video!

Pharmaceutical wise.. so does this pretty much only apply to stimulants? Also can you do a explanation on synaptic gating
thank you so much😭😭😭😭

Energy is not required when a substance is moving from an area of higher concentration to an area of lower concentration.
❤ Great
Now do action potential & brainwave generation

it's 5 minute neuroscience for me B)
