Your brain is a complex network that processes vast quantities of information every second. Part of the brain’s information-processing network includes neurons, or cells that transmit signals throughout the brain. Neurons send signals through neurotransmitters, which are chemicals some release and others receive. These chemicals essentially let the parts of the brain communicate with each other.

The three most commonly studied neurotransmitters are dopamine, serotonin and norepinephrine. Dopamine is related to experiences of pleasure and the reward-learning process. In other words, when you do something good, you’re rewarded with dopamine and gain a pleasurable, happy feeling. This teaches your brain to want to do it again and again. Serotonin is a neurotransmitter associated with memory and learning. Researchers believe it plays a part in the regeneration of brain cells, which has been linked to easing depression. An imbalance in serotonin levels results in an increase in anger, anxiety, depression and panic [source: Nazario]. Norepinephrine helps moderate your mood by controlling stress and anxiety.
