The cholinergic synapse is a key interdisciplinary research topic. It is the basis of the first generation of anti-Alzheimer drugs, of nerve agents and insecticides, of botulinum toxin and the South American Indian arrow poison and of drugs for myasthenia gravis and glaucoma. Providing a cutting edge profile of research progress in this important field of study, this volume contains a compilation of the proceedings of the Eleventh ISCM, held in St. Moritz in May 2002. The book brings together 250 participants from 30 countries, presenting a comprehensive picture of the cholinogeric field.
