WebNeurotransmitters relay messages by traveling between cells and attaching receptors on target cells. Each neurotransmitter binds to a different receptor, for example, the molecule dopamine attaches to the dopamine receptor. After the neurotransmitters deliver messages, the body breaks them down or recycles them. 2. How neurotransmitters work. WebJul 21, 2024 · Excitatory neurotransmitters are chemical messengers that excite, or stimulate, a nerve cell, making it able to receive critical information. Glutamate is made in the body's central nervous system (CNS) through the synthesis of glutamine, a glutamate precursor, meaning it comes before and indicates the approach of glutamate.
