Neurotransmitter (plural form: neurotransmitters) are chemical messengers that enable communication between neurons (nerve cells) in the nervous system. They play a vital role in various physiological processes, including transmitting signals between neurons, regulating various bodily functions, and modulating mood and behavior.

Neurotransmitters are synthesized within neurons and released into the synapse (the gap between two neurons) through the process of exocytosis. There, they bind to specific receptors on adjacent neurons, triggering a series of chemical reactions that ultimately lead to the transmission of a signal.

Some of the most well-known neurotransmitters include dopamine, serotonin, and acetylcholine. Dopamine is involved in reward processing and motor control, while serotonin is responsible for regulating mood and appetite. Acetylcholine, on the other hand, plays a key role in muscle contraction and the transmission of nerve impulses.

Neurotransmitter systems are complex and can interact with one another in a variety of ways. Imbalances or dysregulation in neurotransmitter systems have been linked to a range of neurological and psychiatric disorders, including depression, anxiety, and Parkinson's disease.

The study of neurotransmitters has led to the development of various therapeutic strategies for treating disorders related to neurotransmitter dysfunction. This includes the use of psychotropic medications, such as selective serotonin reuptake inhibitors (SSRIs), which aim to restore balance to disrupted neurotransmitter systems. Research continues to uncover new insights into the workings of neurotransmitters and their role in maintaining proper neurological function.
