Covers all aspects of the structure, function, neurochemistry,
transmitter identification and development of the enteric nervous
system

This book brings together extensive knowledge of the structure
and cell physiology of the enteric nervous system and provides an
up-to-date synthesis of the roles of the enteric nervous system in
the control of motility, secretion and blood supply in the
gastrointestinal tract.

It includes sections on the enteric nervous system in disease,
genetic abnormalities that affect enteric nervous system function,
and targets for therapy in the enteric nervous system. It also
includes many newly created explanatory diagrams and illustrations
of the organization of enteric nerve circuits.

This new book is ideal for gastroenterologists (including
trainees/fellows), clinical physiologists and educators. It is
invaluable for the many scientists in academia, research institutes
and industry who have been drawn to work on the gastrointestinal
innervation because of its intrinsic interest, its economic
importance and its involvement in unsolved health problems. It also
provides a valuable resource for undergraduate and graduate
teaching.

John Furness is an expert on the enteric nervous system and its functions and has published over 300 relevant papers. In addition to his academic roles, he is a consultant in the GI drug development programs of GlaxoSmithKline, Novartis and Pfizer and has contracts with GSK and Pfizer for target identification and lead compound testing. Relevant honours include: Distinguished Achievement Award, Australian Neuroscience Society, 2003 Davenport Medal, American Physiological Society, 1997 Grossman Lecturer, Cambridge, 1995 (The field of the Grossman Foundation is gastroenterology) Australian Physiological and Pharmacological Society Lecture and Medal, 1995 Distinguished Research Prize, Gastroenterological Society of Australia, 1994 Janssen Research Award, 1993 (The field of the award is gastroenterology) Fellow, Australian Academy of Science, Elected 1989

Index.

"As someone who has contributed extensively to our current
understanding, John Furness provides an insightful and personal
account that integrates a vast array of literature into a nicely
illustrated and very readable book that will be of interest to
anyone working in the field."

Professor David Grundy, European Journal of Gastroenterology
& Hepatology

"Each chapter is very well written, focused on the specific
topic and easily understandable. Also, the text has been widely
integrated by more than sixty high-quality schemes, illustrations
and drawings... Furthermore, the entire book has been well
supported by classic publications and updated literature making all
together more than 12000 references in all."
