Biogenic amines are naturally occurring amines that are derived by enzymic decarboxylation of the natural amino acids. They belong to a class of neurotransmitters including catecholamines (dopamine, norepinephrine, and epinephrine), indolamine (serotonin), and imidazoleamine (histamine). Biogenic amines have great pharmacological and physiological importance. The main objective of this book is to present readers with comprehensive information on pharmacology, neurochemistry and molecular neurobiology of biogenic amine in the CNS of vertebrate and invertebrates in a single volume text. The book has been organized into chapters and sections to provide a better flow of information. Furthermore, this unique volume provides its readers with cutting edge information on biogenic amines. It can be used by graduate students, postdoctoral fellows, researchers, and scientists who work at the pharmaceutical industry as a handbook, which describes all aspects of biogenic amine metabolism.
