How do excitatory neurotransmitters differ from inhibitory neurotransmitters?

Neurotransmitters are classified as excitatory or inhibitory according to their effects on postsynaptic membranes. A neurotransmitter is called excitatory if activation of the receptor causes depolarization of the membrane and promotes action potential generation. A neurotransmitter is called inhibitory if the activation of the receptor causes hyperpolarization and depresses action potential generation.
