Neurotransmitters and Neuroactive Peptides. Communication of information between neurons is accomplished by movement of chemicals across a small gap called the synapse. Chemicals, called neurotransmitters, are released from one neuron at the presynaptic nerve terminal.ommunication of information between neurons is accomplished by movement of chemicals across a small gap called the synapse.
Once the neurotransmitter is picked up by receptors in the postsynaptic membrane, the molecule is internalized in the neuron and the impulse continues. This process of nerve cell communication is extremely rapid. Neurotransmitters are chemicals that transmit messages from one nerve cell (neuron) to another.eurotransmitters can excite or inhibit neurons (nerve cells). Some common neurotransmitters are acetylcholine, norepinephrine, dopamine, serotonin and gamma aminobutyric acid (GABA).
