What happens to the membrane potential during hyperpolarization?
Understand the Problem
The question is asking about the changes in membrane potential during the process of hyperpolarization, specifically which of the provided options accurately describes this phenomenon.
Answer
The membrane potential becomes more negative.
During hyperpolarization, the membrane potential becomes more negative than its resting potential.
Answer for screen readers
During hyperpolarization, the membrane potential becomes more negative than its resting potential.
More Information
Hyperpolarization increases the negativity of the membrane potential, typically making it more challenging for neurons to reach the threshold potential necessary for action potential propagation.
Tips
Confusion often arises between hyperpolarization and depolarization. Remember that hyperpolarization is associated with increased negativity, while depolarization involves a decrease in negativity (more positive).
