<h3>What are Neurotransmitters?
</h3>
Neurotransmitters, which are organic compounds, play a major role in the language that neurons use to communicate with one another and with their final targets. Following electrical stimulation, these substances are produced and act on their particular receptors to start a response that can be as simple as a muscle contraction or as extremely complex as starting a chain reaction that eventually changes how the organism behaves. Neurotransmitters can have multiple functions; depending on where they act, they can be neuromodulators or, in some cases, neurohormones.
