Additionally, neurotransmitters chemically link the brain and spinal cord with the rest of your body: muscles, organs, and glands. Thus, our brain is not only an array of wires (nerve cells/neurons) but also a highly evolved chemical soup (neurotransmitters). Neurotransmitters affect every cell, tissue, and system in your body.
There are many types of neurotransmitters in the brainâwhat they have in common is that they are produced inside a neuron, released into the synapse, and then cause an excitatory or inhibitory effect on receptor cells, helping to propagate or downgrade action potentials.t was also once believed that only neurons released neurotransmitters. New research, however, has now demonstrated, glia, the cells that make up the brainâs âwhite matter,â also releases neurotransmitters into synapses.
