The opening of sodium channels in the axon membrane causes depolarization.

Here's a step-by-step explanation:

1. At rest, the inside of the neuron is negatively charged compared to the outside. This is due to a higher concentration of positively charged sodium ions outside the neuron and a higher concentration of negatively charged proteins and nucleic acids inside the neuron.

2. When a neuron is stimulated, sodium channels in the axon membrane open.

3. Sodium ions, which are positively charged, rush into the neuron due to the concentration gradient and the electrical gradient.

4. This influx of positive charge makes the inside of the neuron less negative, or more positive, compared to its resting state. This change in electrical charge is called depolarization.

5. Depolarization is the first step in the generation of an action potential, which is the electrical signal that neurons use to communicate with each other.
