    I made a mistake...
    Mistake: Magnitude of action Potential = 135 mV.
    Correction: Magnitude of action Potential = 125 mV.

    Great video, but consider the posibility that the de/re-polarization is simply how a BIO-CONDUCTOR regenerates itself? (nature's copper wire) And yes! The actual data is communicated at the speed of light? That would explain our consciousness?

    • @NewtonMD
      @NewtonMD 11 месяцев назад

      No the actual data is communicated when the positivity reaches the neuron terminal which is not near light speed, and NO light speed does not explain consciousness.

    It's type B fibers... Just URM 🤭
    But I was wondering... If the AP depolaryzation comes from -90 to +135... Then the value of Na+ is a functional value or something? 👀

    • @eduardoparedes6750
      @eduardoparedes6750 3 года назад

      Oh yeah, i mean, the value of the extracellular sodium is a functional value? Because it rise the action potential from -90 to +135 in a equivalent value of it's normal value as an extracelular ion... Then we can consider it a functional value? Or is just a random fortuity... 😁 Thanks master for your interest in all your Padawans, love your perfect perfectionalis work!

    • @onweed3626
      @onweed3626 2 года назад

      To 35+* ... and do you mean a functional value like is it a constant, certain or a measured value that let's say "this amount needs to be influxed" for an action potential to occur?

  • @Jeff-zc6rr
    @Jeff-zc6rr 6 месяцев назад

    i'm sorry.. horrible demonstration of why sodium is faster. If the sodium can get through at 45 degrees why can't the potassium? and why can't it just open and close 45? then it would be the same speed.

      He's describing the effects of the double gated Na channels and single tasted K channels, this is the reason for the variation in speed. Hope it helps.
