An excitatory neurotransmitter depolarizes the postsynaptic membrane.

Here's the step-by-step explanation:

1. Neurotransmitters are chemicals in the brain that transmit signals from a neuron to a target cell across a synapse.

2. An excitatory neurotransmitter is a type of neurotransmitter that increases the likelihood that the neuron will fire an action potential, or "nerve impulse."

3. The action of excitatory neurotransmitters is to bind to the postsynaptic receptors and cause an electrical change in the postsynaptic membrane. This change is called depolarization.

4. Depolarization of the postsynaptic membrane means that the difference in electric potential between the inside and outside of the neuron is reduced. This makes it more likely that the neuron will fire, sending a signal down its axon.

5. Therefore, we can say that an excitatory neurotransmitter depolarizes the postsynaptic membrane.
