James took some cocaine, which caused him to have a euphoric rush of well-being. His experience is attributable to the increased activity of the neurotransmitter <u>dopamine</u>.
Dopamine, also known as DA or 3,4-dihydroxyphenethylamine, is a neuromodulatory chemical with a variety of crucial functions in cells. It is an organic substance that belongs to the phenethylamine and catecholamine families.
About 80% of the brain's catecholamine content is made up of dopamine. It is an amine produced by removing a carboxyl group from a molecule of L-DOPA, which is used as a precursor and is produced in the kidneys and brain.
Plants and the majority of animals can produce dopamine as well. Dopamine performs the role of a neurotransmitter in the brain, which is a substance secreted by neurons (nerve cells) to communicate with other nerve cells.
Although they are produced in certain parts of the brain, neurotransmitters have a systemic impact on numerous areas. There are multiple unique dopamine pathways in the brain.
