“…The volume starts with a detailed and interesting historical overview of the cholinergic system written by Dr. Alexander G. Karczmar; from the early anatomical studies and application of medicinal plants with cholinergic properties, by shamans, hunters, medicine men and mystics, to the latest discussion of the contribution of muscarinic acetylcholine receptor, members of the G protein-coupled receptor (GPCR) superfamily, to behavioral, psychological and mental function (Karczmar, 2009). Dr. Karczmar is Professor Emeritus of Pharmacology at Loyola University Medical Center, USA, and has devoted more than 6 decades of his life studying various aspects of the cholinergic nervous system.…”
