Question

4. Describe the relationship between an intracellular and extracellular action potential (eap). How does the shape of the eap dependent on the position of the electrode?

Answer 1

Both the classic intracellular action potential and the compound action potential are biphasic. In other words, they have both positive and negative deflections, but for different reasons. The negative phase of the intracellular action potential is attributed to the mechanism of after-hyperpolarization.
