Na+ Channels: Open at Resting Potential or Threshold?
Want To Learn More? To watch the entire video and ALL of the videos in the series:
Discover the mechanics of voltage-gated Na+ channels and their role in neuron activity. This video breaks down key neuronal terms like resting potential and threshold to explain precisely when these channels open. You'll come away understanding that voltage-gated Na+ channels open at the threshold state initiating an action potential.
