Sorry, but I found the book disappointing. The author notes in the first few pages the book is "an idiosyncratic account of my own understanding of several central issues of cognitive neuroscience and of the personal context that let me to write about it" and that's an understatement. Highly personal and very idiosyncratic are the watchwords. If you are looking to gain an understanding of the frontal lobes and executive functions you will find this book comes up short. Zero attempt is made to provide even highlights of the most necessary topics, or even a cursory and minimally sufficient survey of well-accepted research in this area. At best you have a few good points raised. Even those however are difficult to distinguish from personal bias and preference.
Chapter one is a sales pitch for the rest of the book with virtually no information presented. Chapter two is an odd account of the author's career, again with no information presented. The end few chapters are likewise completely tangential. Having excised the filler, what's left is very thin. References are likewise scant and the index is an embarrassment.
The coup de grace however was the patently offensive entire chapter advertising the author's private clinical services. Aimed at attracting aging but otherwise high functioning, bright people, who presumably make clinical work more palatable, the service offered is to rejuvenate or improve aging mental horsepower. I hope the idiosyncratic and highly personal techniques employed in clinical practice are more effective than the content delivered in this book. None of the cognitive techniques are actually discussed, even superficially. One can only hope they carry the same warnings as the herbal supplements - "these treatments have not been tested, and are not approved to diagnose, treat, cure or prevent any disease." Likewise perhaps the title of the book could be changed to "Selected Memoirs of a Neuropsychologist."
