Neurotransmitters are quite diverse in their action. Some are excitatory, some are inhibitory, and for some the effect depends on what kind of receptor the postsynaptic cell has. Some neurotransmitters open ligand-regulated ion gates while others act through second-messenger systems. Bearing this diversity in mind, we will here examine three kinds of synapses with different modes of action: an excitatory cholinergic synapse, an inhibitory GABA-ergic synapse, and an excitatory adrenergic synapse.
