I had bought this book with high hopes based on the reviews and description. Make no mistake, this is a user's manual for several types of specific equipment (EEG-type) with very little background on how to interpret the readings or, more generally, on the various aspects of the neurofeedback field, or other methods of neurofeedback. This is a book by a pratitioner for a starting practitioner (dealing with how to set-up electrodes, how to read charts, a summary of a couple dated EEG systems, and how to choose an office space).
It does NOT cover in any detail theory or discuss latest research. Even as a reference for equipment/setup a quick internet search revealed several much more advanced systems available that were not even mentioned by the book. The book references DOS-based systems and alludes to Windows based systems.
If you are starting a business in this area and already have a firm grasp on the fundamnetals of this field then perhaps this book MIGHT be helpful, but anyone looking for an in-depth treatement of the wide range of neurofeedback techniques and/or comprehensive treatment of brain physiology/activity under different conditions should steer clear of this book - you will be disappointed. I am just glad Amamzon refunded my money.
