Answer:

Sodium ions move into the postsynaptic neuron causing depolarization of the

postsynaptic neuron

Step-by-step explanation:

That's the mechanism of action potential generation. Neurotransmitter receptors are connected to sodium channels. When those sodium channels open the cell becomes depolarized(the charges reverse), that means the inside of the cell becomes more positive while the outside becomes negative
