neurotransmitter

Neurotransmitters are chemical messengers in your brain that transmit signals between nerve cells (neurons). When a neuron wants to communicate with another, it releases these chemicals into the space (synapse) between them. The neurotransmitters then bind to receptors on the receiving neuron, triggering a response—like passing along a message. They play a crucial role in controlling mood, thought, sensation, and bodily functions. Different types of neurotransmitters, such as serotonin, dopamine, and norepinephrine, are involved in various brain activities and can influence feelings, behavior, and health.
