Equilibrium Potentials and Driving Force

Ions move in response to concentration gradients and voltage gradients... but when the ions move, the gradients change! WHY do they move? Do they ever reach an equilibrium? Do you really need physics to understand this? Not really - although I throw it in at the end! Don't worry - it's the Nernst Equation, Penguin Prof Style!

the topic was so confusing while reading the book but now it seems pretty easy
thanks for such an incredible explanation

[SukhdipKaur]

Thank you for explaining! Its so sad that our education system can't slow down to explain these concepts, rather it wants us to memorize everything.

[jaimechristiaanse]

Best video ever for explaining these concepts, super helpful, love everything about it!!

[franckboismoreau]

Hello,

I'm a French student in Neuroscience and I just want to thank you so much for this amazing video which made me understand those two points very easily and quickly.
What do you is amazing :)

[karinamatos]

I'm having a eureka moment! Thanks for this exceptional explanation.

[Jessthenursecoach]

I love the first half of your original video and how you use the human experience. I thought, about you doing a future video or podcast translating your knowledge as it relates to to all areas of the every experience of the human condition.Just throwing out an Idea.

God I can’t say how this was useful and English is not even my first language! That was so clear and well explain!
Chapeau !

i love your voice, u explained the concept very well, thank u

I think it's the brain that determines the driving force based on a person's beliefs and only a change in beliefs can change it, either individually or collectively. I also believe that consciousness is demonstrated by it's ability to change the condition and position of any particle from its otherwise inevitable position and the inevitable position of any particle is also determined by conscious intention. There is no difference between the laws that govern the interactions of people, atoms, events, or anything, because everything is made of pure imagination. Ironically, that's why a good deed shines so in a weary world. Know what I mean?

Are you still making videos? For me, these are brilliant. What a great teacher!

[swairaazhar]

Very helpful. This video really cleared my concepts.

[sonnicasteel]

I've learned more watching your videos in the last 20 minutes than 6 weeks of attending Neurobiology lecture. I wish you had more videos on the neurons and cell biology. Thank you so much!!!

[funnnkykd]

Amazing. I was stuck in these details for hours..

[dastui]

Really great video, the analogy was awesome. LOVED IT!!!

[poling]

Do you happen to have a video showing how to actually do the Nernst equation from start to finish?

[KK-fqsm]

The definitions are starting to get more clear.

[goom]

Thank you so much for the lesson, but I have a question that you might have help me with finding an answer to.
What if we, humans, were wrong? with all the numbers and all the formulas. I know that might seem a little stupid, but i really have been thinking a lot about a lot of things that happen in our universe. What if we've found something much faster than light? that's one things I have been dreaming of. We have based our learning on numbers, constants and theories. I think we need to work harder. who knows, we might someday harness power from other stars, or apply the first Warp Drive. Thanks again, and by the way your teaching analogy is perfect. Keep up....

[audrey]

Oh that's really helpful ! thank you so much !!

[Frogadventure]

omg thank you so much it's a few days I been struggling with this and you made me understand it

[sashathomas]

thank you, im a msc student doing neuroscience and biochemistry and have a question, no one ever really explains why we must use logarithmic form, im assuming this calculation is based onlogarithmic transformation, and have been told this info does not exist because in the olden days researchers never had calcultors, eg the work by kessel on the k+ of frog, leech so theefor it was compulsory to know logs and why we use them. My lecturer has said that we won tunderstand them because of calculatorsand lack of communication with high school. So why do we use logarithmic transformation with the nernst equation for membrane potentials, reversal potentials and how does it relate to why graphically in K+ decade change is -60mvs?
