Molecular and Basic Mechanisms of AnesthesiaB.W. Urban & M. Barann (editors)
This book contains condensed papers of the contributions presented at the "Sixth International Conference on Molecular and Basic Mechanisms of Anesthesia", held in Bonn in June 2001. Ascending the hierarchical order of the central nervous system from molecules to intact organisms, the materials have been arranged following the organization of the conference: Molecular Basis of Anesthetic Interactions, Anesthetic Interactions with Ion Channels and Other Proteins, Integration of Anesthetic Actions (In-Vitro) and, finally, In-Vivo-Networks. In addition to insights at the molecular level, exciting results have been obtained from the various in-vitro slice preparations and from in-vivo electrophysiology as well as from in-vivo functional imaging, indicating a much higher level of complexity than originally appreciated.
