The neurotransmitter dopamine (DA) has several important functions. For instance, it known to play a role in how we feel pleasure, as well as in our ability to concentrate on everyday task, maintain focus, and learn specific ...
The neurotransmitter dopamine influences the activity of a wide variety of brain areas. A deficiency of this substance can have drastic consequences: The death of dopamine-producing nerve cells in the substantia nigra—a ...
