Stress and the Brain [PDF ebook] 
The Science of Mental Health

First published in 2002. This is Volume 9 of a collection of ten works on the science of mental health. This volume in the series focuses on issues related to stress and the brain. Although stress affects many other aspects of physiology, they are beyond the scope of this volume. The volume begins with a seminal work by Selye describing the stress response, an adaptive response that permits an organism not only to survive but also to cope with the stressor.
