Action Potential | Graded Potentials
In this video, Dr Mike explains everything you need to know about how neurons send signals via action potentials!
He also discusses different types of graded potentials including;
- excitatory postsynaptic potentials (EPSPs)
- inhibitory postsynaptic potentials (IPSPs)
And what role neurotransmitters like glutamate and GABA play!

You have no idea how much your videos helped me. I'm a slow learner and need repetition, and your methods make everything so clear. I can rewatch your videos and get confident in knowledge. I graduated my program with a 4.0 and I think largely thanks to having access to your videos. Thanks SO much.
your teaching style is unmatched - superb content!
I noticed that KZread is featuring this video. Normally I wouldn't care............ .................BUT............"Action Potential" is probably Drs Matt and Mike's best video. Action potential is almost never explained clearly. I've watched many videos on it, and they're almost always bewildering. I was bewildered by action potential........until I watched this INCREDIBLE VIDEO. Made me a fan forever.
After reading from my book i can't understand....but after watching your explanation finally i have a clear cut thoughts about this topic Thanks 😊 Only the students like me fell how much worth your video😊😊😊
I was so confsued about this concept, but holy crap this changed my whole view of electrical signaling subject, Thanks for the great video!!

I have a test on the nervous system today, thanks for the very well-timed refresher video
Thanks you dr mike, from today I am one your students. I want to say, you are the best person to explain and teach someone like me. I understand very well. Thanks you please keep more🎉
Another amazing video. Reviewing content for my paramedic exam and this helped so much !
I was so confused by lecture notes and was sad, suddenly I noticed this video first and watched it. This video literally cleared my doubts and Big THANKS TO DR MIKE FOR MAKING OUR DAYS BETTER.
And just like that I feel confident to answer any question related to action potential.. Thank you ❤
Honestly I just subscribed right after watching only 2 videos, this is real high quality content & this is really better than some paid contents available. Huge thanks for such great content Doc. U r doing great, keep it up. 👏👏👏

Yet again high quality content. Thanks!
Please make a video for propagate of action potential and solitary conduction
The best explanation yet! Thank you so much for your videos!
Thank you so much Dr. Matt. This video helps a lot with my studies.
Thanks Dr Mike great to see an Aussie leading the way in this type of type of education - shame your not teaching at University of Newcastle, NSW but truly thanks for all your help it goes a long way. 🇦🇺
You've just gained a subscriber after watching 2videos.. thank you Dr matt. Your teachings are very helpful and easy to understand 🥰🥰
Hii sir I'm from India 🇮🇳 and your lectures are really helping me a lot in my highschool studies 🙏🏻 thanks a lot
Thank you so much. I had trouble understanding with some of my diagrams but this one made it really clear. Thank you for your efforts.
So well done. Thank you!
yo Dr. Mike you lowkey saved my anat and phys grade so thanks for that but also you’re actually jacked please drop the routine
Thank you Dr Mike ❤❤
Crazy, you hit all the marks! Definitely got another subscriber just now!
Brilliant explanation!
Appreciate your work sir❤ i was having so many doubts related to this topic but after this video my doubts are cleared . Thanks a lot sir❤
Thank YOu! i have online anatomy and i had no idea how to figure this out. YOu explained it so clearly. thank you.
Perfect explanation👍🥇
I'M WAITING!!!😍😍😍

Thank you so much for explaining well.
Great explanation. I wish I watched this before my final Anatomy exam loll I would have ended the class with an A!
You're exceptional 👏
Excellent work! Loved this lesson; brilliantly structured explanation. 1 question: Do positive sodium or potassium ions get attracted towards negative areas due to opposing charges or move away from each other by same change repulsion? Same outcome but subtely different reason? And I read somewhere that only small numbers of ions need to move to cause these charge changes?
You are my fav Dr, you helped me so much and I hope you keep up the great work
Best dr.♥️♥️
I never understood this In class I'll stop attending lectures and watch you videos instead
This is completely mind blowing. I love your videos😍

Hello Dr.Mike..please do the special senses
GOAT 🐐👍🏼
How much EPSP take ?? And how mucjh AP take ??? I heard from my leacturer that EPOS ×10 than AP
THANK YOUUU

Hey are you guys not doing podcasts anymore?
Which Na channels have inactivation gate?
I thought they went across the synapse in a vesicle rather than diffused. That’s confused me a bit 😅 formative exam on Monday. Summative 16 days later

Vesicles containing the neurotransmitters actually fuse with the membrane of presynaptic neuron and "dump" the neurotransmitters outside into the synaptic cleft, and that's how they diffuse across, until they reach postsynaptic receptors. I know you are long finished with your exam but hopefully this response can help someone else. FYI ... vesicles can't leave the membrane which is why it's considered exocytosis - "exo" - outside, "cytosis" - cell

1.for 3Na Out +2 k in-- causing negativity inside-ok.2.excitation - works on Na+ Ca channel. 3.inhibitory - acts on K channel.2.excitation and inhibition always work on in same time????.pl.sir. Give ans.

I am not sure about any rare cases. However, based on the definition, if AP occur, it should be a depolarizing period before the AP can occur and it means the cell is being experienced EPSP. If it strong enough, the summation of these Graded potential (EPSP) such as the appearance of Glutamate then enough positive so become AP. Otherwise, if there is the appearance of GABA, the neutron is experienced IPSP, it means the cell becoming more negative and far away from threshold to be depolarizer so AP cannot occur. And AP characteristic is “all or non”, which means fired or not fired. You question about if EPSP AND IPSP can happens at same time or not, I believe the same time if EPSP and IPSP is during the summation of GRADED Potential, if 2 EPSP OCCUR WITH 2IPSP, then it will be canceled out and no AP occur! This is my opinion based on what I understand! If you have more idea about it, please correct me!
stoppp😂 why the thumbnail HSHAJAJ
Voltometer lol. Think you meant voltmeter.
