Although somewhat out-of-date (frequently referring to the physiological and psychological developments of the 1970s), this book provides a thorough account of Ivan Pavlov's life and his research in physiology and behavior.

As a clinican working with anxiety patients, I am very impressed of the authors' efforts in making research and summary upon the neurological hypothesis for anxiety, particularly for the role of septo-hippocampal system for anxiety and GAD problems. The authors have listed out the evidence to support their arguments with a lot of experimental and animal studies. Their approach is rather biological, and may need a good biological background for better understanding. No matter what, it is no deny upon biological elements in anxiety. It is not easy to read and understand the book, but it is very meaningful and fruitful to do so !
