The good news: the U.S. is making a tectonic shift from burning coal to produce the majority of its electricity to using cleaner natural gas. The changeover produces less CO2, making electric cars cleaner across the country, roughly equivalent to a hybrid.
Dopamine is a neurotransmitter, a chemical responsible for sending messages between the brain and different nerve cells of the body. It's responsible for many functions, including memory, sleep, mood, pleasurable reward, behavior and cognition.
Dopamine is an important neurotransmitter found naturally in the brain. Dopamine (and norepinephrine) belongs to a subcategory of monoamines called catecholamines. The chemical structure of dopamine is C 8 H 11 NO 2 as is depicted in the picture above.
