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 organic chemical of the catecholamine and phenethylamine families that plays several important roles in the human brain and body, as well as elsewhere in biology.Its name derives from its chemical structure: it is an amine formed by removing a carboxyl group from a molecule of L-DOPA.In the brain, dopamine functions as a neurotransmitter âa chemical released by nerve cells to send signals to other nerve cells.-DOPA, the metabolic precursor of dopamine, does reach the brain and is the most widely used treatment for Parkinson's disease. Dopaminergic stimulants can be addictive in high doses, but some are used at lower doses to treat ADHD.
