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 a catecholamine neurotransmitter that activates five known types of dopamine receptors (D1 through D5) and acts as a precursor for the neurotransmitters norepinephrine and epinephrine. Dopamine plays an important part in most aspects of human consciousness, including âpunishment and rewardâ.
