neuromodulators

Neuromodulators are chemicals in the brain that help regulate how neurons communicate with each other. Unlike neurotransmitters, which transmit direct signals between nerve cells, neuromodulators influence the strength and duration of these signals, affecting mood, pain, focus, and various brain functions. They can enhance or dampen the activity of neurotransmitters and often work over longer timeframes. Common examples include dopamine, serotonin, and norepinephrine. Through these actions, neuromodulators play a crucial role in processes like learning, emotion, and stress response, making them integral to our overall brain function and behavior.
