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.
Key points. 1  Neurons communicate with one another at junctions called synapses. At a synapse, one neuron sends a message to a target neuronâanother cell. 2  Most synapses are chemical; these synapses communicate using chemical messengers. Other synapses are electrical; in these synapses, ions flow directly between cells.
