There are 4 important classes of proteins in the membrane of neurons: Passive/Leakage ion channels, Sodium-Potassium pumps, Voltage-gated ion channels, and Ligand-gated ion channels. In order to understand how the neurons functions, we have to understand how those channels work. Watch the following video to learn about these proteins.

  • Hey :) Which cell membrane was the diagram referring to, is it a cell of the skin, or a nerve or something else?

  • Hello! I’ve just begun listening to these episodes. Every single video has been clear, concise, and truly the best introduction-to-neuroscience series I’ve encountered yet. I’m going back through several of the videos again, from the beginning, and now that I’m going back through I’d like to ask a few questions, if you are still available for commenting on some of these earliest videos?

    Anyway:
    In this episode, you spend some moments talking about the Sodium-Potassium. I am curious how this process actually works. How is it that something like a “Sodium-Potassium” pump can exist? I don’t understand the process behind a biological structure being somehow able to distinguish between sodium and potassium? Why is it pumping? Also, how is…/motion/ happening? Does this require energy? and more ATP?

    Again, I should say that I am not at /all/ a neuroscience or biology student, so perhaps these questions are very trivial. But I am very interested in all of this. Fantastic series.

  • Lectures in college are terrible. I learn more in a 10minute video than the whole year in college something is not right I am basically paying tuition fees to write exams because I learn nothing. Thank God for great online teachers like you. Sighs

  • Is it right to believe that the passive ion channels are a form of diffusion?

  • how would you expect the strength of an electric current across an ion channel to compare with the strength of across an ion pump?

  • Thanks you so much. These video’s are really helping me to break down what I have read in school and puts a more entertaining view/spin on it. Your videos are of the best I have seen. You are helping me to pass my major exam coming up in June. Thanks again!!!!!

  • Thank you so much! But I want to share some positive critic with you, I think you should lower the music volume a tiny bit, because I am more interested in hearing your voice than the music :)

    Keep up the work!

    hi there, great video, i was wondering if you had any video that talks about chloride ion , and the chloride ion channels, and what can happen if the chloride ion is not able to pass out of the cell membrane

    you are great im been taking bio classes but I never had a prof capable of explaining this information. They have not clue what they lecture.

    Tell me about it! Don’t you hate when you pay so much money for university classes and than end up learning from various sources like youtube, or random lectures on-line??
