What are the main classes of neurotransmitters?

Neurotransmitters are key chemicals that allow communication between nerve cells, or neurons, in the human body. There are several main classes of neurotransmitters, each with their own distinct functions and effects. The first class is the amino acid neurotransmitters, which include gamma-aminobutyric acid (GABA) and glutamate. GABA mainly acts as an inhibitory neurotransmitter, reducing brain activity, while glutamate is an excitatory neurotransmitter, enhancing brain activity. The second class is the monoamine neurotransmitters, which are derived from amino acids. Some examples include dopamine, serotonin, and norepinephrine. These neurotransmitters regulate mood, arousal, and motivation. Lastly, there are the neuropeptides, which consist of small proteins that modulate various physiological functions, such as pain, appetite, and stress response. Understanding these different classes of neurotransmitters is crucial in comprehending the intricacies of brain function and the role they play in our mental and physical well-being.
