Introduction to clinical psychophysiology, a class I teach in the Master's degree counseling program at St. Mary's University of Minnesota, Minneapolis. The text I use with this class is Andreassi, JL (2007)Psychophysiology: Human Behavior and Physiological Response (Paperback), 5th Edition, ISBN 978-0805849516. A Kindle version is also available at Amazon. Not the newest book but lots of history and a good introduction to begin getting up to speed using the principles of psychophysiology in helping people regulate stress, anxiety, depression, even epilepsy.
