 Hyperpolarization (biology)

In biology, hyperpolarization refers to a change in a cell's membrane potential that makes it more negative compared to the resting membrane potential. This occurs primarily in neurons and muscle cells and is an essential aspect of how these cells function in response to stimuli. ### Mechanism: - **Resting Membrane Potential:** Normally, a cell maintains a resting membrane potential, typically around -70 mV in neurons.
