Nernst Equation And The Electrochemical Gradient Explained | Clip

Welcome to Science With Tal!

In this clip of the Signal Propagation in the Neuron video, we will discuss how we can mathematically obtain the equilibrium potential for ions involved in neuronal signalling by using the Nernst equation. You will see here and in the comment section the time stamps associated with each topic that I’ve covered.

To improve the quality of my content, I highly value the feedback from the viewer so do not hesitate to give any feedback in the comment section.
