*Remember to load your trailer with more weight in front of the trailer axle than behind it. A trailer with too much weight on the back end can put it and the tow vehicle into a violent and uncontrollable wag that can literally flip the tow vehicle. Overloading a trailer can cause serious injury or equipment damage.
Most recent answer: Dopamine is both a hormone and a neurotransmitter. It acts as a hormone in the blood and as a neurotransmitter in the central nervous system.
Dopamine is a neurotransmitter, a chemical used to carry messages between neurons. Dopamine is produced in several areas of the brain, including the substantia nigra. Dopamine's effects are complex and poorly understood, but dopamine appears to play a role in signaling reward in the brain.arkinson's disease destroys dopamine-producing neurons in the substantia nigra, and causes motor symptoms (dyskinesia, tremor, rigidity) as well as cognitive symptoms. The motor symptoms can be treated by drugs that increase brain dopamine levels.
