All about Dopamine
Dopamine is an essential neurotransmitter, a brain chemical that helps neurons communicate with each other and with other cells. Neurons are like mini computers, analyzing and coordinating everything happening at thousands of points of contact with other neurons. For every thought you have and action you take, dopamine and other neurotransmitters are zapping into the receptors that stud each of the thousands of dendrites on billions of neurons!
Dopamine plays a role in pleasure, movement, motivation and cognition. Activities that cause the release of dopamine include exercising, cooperating, having healthy relationships, and eating or even just anticipating eating sweet foods. Along with its main job of regulating and influencing thinking, dopamine also controls production and release of many hormones, such as those crucial for your response to stress.
Chronic stress or pain can deplete dopamine and decrease the sensitivity of neurons to stimulation. This may result in the inability to feel pleasure, a defining symptom of depression. Certain illicit drugs cause overproduction of dopamine. Such drugs can hijack your brain’s own pleasure-reward system. Other drugs work by neutralizing cells that normally reduce the production of dopamine.
Dopamine controls the information flow from one brain area to another and it is synthesized in many brain regions. One region helps initiate movement, so damage there can lead to Parkinson’s disease, characterized by the loss of muscle control. Another region regulates the release of the pituitary hormone. And yet another is about reward and, in that region, various pleasurable stimuli will activate neurons to release dopamine.
