AP Psychology
Unit 2 – Biological Basis of Behavior
Topic 2.4
Why would we argue that depolarization plays a central role in action potentials?
Depolarization leads to a change in charge within a neuron and triggers an action potential if it reaches threshold level.
Depolarization slows down the speed at which an action potential travels along a neuron's axon.
It balances out hyperpolarizations that could otherwise inhibit firing capabilities of neurons.
Depolarization contributes mainly to resting potential maintenance rather than initiating action potentials.
