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.
Synapse. There are chemical synapses, and  electrical synapses; chemical synapses involve  neurotransmitters diffusing across a small space between the  neurons, and electr â¦ ical synapses involve a much smaller gap called  a gap-junction, where ions move through channels resulting  in an electrical current.hen a signal reaches the end of a neuron it releases neurotransmitters into the synapse where they bind to receptors to release the second messenger into the next neuron.
