Good first effort towards integrating neuro and econ, September 3, 2003
One of this book's greatest gifts is to clearly explain how our thinking about our thinking (neuroscience) has evolved over the past 2000 years. This book makes a significant contribution to the readers' historical understanding of psychology, philosophy, mathematics, and game theory. One weakness of the book's approach is the lack of references to affect (emotion), which is suggested to have an impact on human utility and probability estimations in (Loewenstein, Loewenstein, Weber, & Welch, 2000), (Slovic, Finucane, Peters, and MacGregor, 2002), and (Knutson and Peterson, 2003). In fact, Glimcher states: "Neuroeconomics provides a model of the architecture that links brain and behavior. Mind, though it may very much exist, simply does not figure in that equation (p343)." The author's conclusions are limited to a logical, computational frame of reference - a form of computational behaviorism. This style certainly has applications within limited experimental games, but it is doubtful that it will provide significant insight into the workings of complex dynamic systems, such as the financial markets, without incorporating symbolic psychological concepts (such as affect). This book is an excellent introduction to the field of neuroeconomics. Glimcher's exposition of the evolution of neuroscientific thought is fascinating and worth savoring. Glimcher's discussion of game theory is fascinating, but applications to real-world environments are not directly posited. The latter half of the book, while intellectually interesting, reads much like an expanded academic journal article. Glimcher explains his lab's experimental trials and tribulations in much of the second half...

Neuro and economics, not neuroeconomics, July 20, 2003
Deisions, Uncertainty, and the Brain feels undigested, as if the author crammed in the library for a month and wrote a book on his notes. Part I covers the neuro-, Part II covers the -economics, but instead of Part III, covering neuroeconomics, there's a 17-page-short chapter called "Putting It All Together." For most of the book, things don't merge. For example, chapter 5 describes important experiments by Newsome and Shadlen that are not really neuroeconomics. Four seemingly tacked-on paragraphs at the end of the chapter argue that neuroeconomics has something to say about the experiments. But it's not clear what that is, and it's not clear why Glimcher didn't choose a more obviously relevant example. A more general problem is that Glimcher argues throughout that current approaches to neuroscience are all reflex-based, and we need a major paradigm shift to make any more progress in brain research. But the examples he gives that employ his new paradigm seem to be well within the realm of normal cognitive neurophysiology. For example, the Ciaramitaro et al. attention experiments described in chapter 13 are elegant, but don't come across as paradigm shifting, in either the chapter, or the original Vision Research paper. Neuroeconomics comes to seem like just another tool in the toolbox, instead of a big new theory. It may be that there is no Part III because the science has not yet happened. In which case, not writing more about it was a good thing to do. Parsimony is a virtue, but if there is not enough of a story to tell, I would have liked to see the author present his ideas about the major problems for the field, a Hilbert's 23 for neuroscience in the 21st century. Instead chapter 13 gives us four toy problems in primate physiology. The best parts of the book are the history. Some of the stories are familiar, but most are not, and all are told engagingly. Although they don't really come together into a cohesive whole, they are interesting on their own, and a reader with a detailed knowledge of the field can connect most of the dots.

Mind-altering book about the mind, December 4, 2005
This is undoubtedly one of the most important conceptual books on the brain I have read in the past decade. Irrespective of how one feels about the author's ideas, familiarity with them is already a prerequisite for any serious philosophical debate about the structure of the mind and free will. This small book with a somewhat awkward title could have been easily called "New Ideas on the Brain and the Mind". It is not another popular book on the brain. It introduces a radically new approach to the brain, but does it so smoothly that stylistically the book reads like Charles Darwin's "The Origin of Species". After you close the last page and look up, you know something has changed.
As with all great insights, the idea the author proposes is deceptively simple. Here is how I'd state it (my apologies for possible distortions):
The anatomy and physiology of the brain have been designed by evolution to look for optimal solutions. The brain appears sloppy, but it is a remarkably precise machine specifically designed to deal with an environment whose true state can never be known precisely. Some optimal solutions will be deterministic, but many optimal solutions will require a truly random behavior. That's it.
This can be shown mathematically (in probability theory and game theory), by observing actual animal behavior (in behavioral ecology), and by studying the brain (in experiments done by Dr. Glimcher and others). Now the mind-body dualism can survive only if it no longer hinges on nondeterministic vs. deterministic behavior. My decision to work or shirk has no longer anything to do with free will - I'm unconsciously randomizing my actions based on the optimal probabilistic strategy that a mathematician can compute. The soul and free will may well continue to exist (I recommend W. James's "The Varieties of Religious Experience" as a relevant reading), but they certainly have to explain themselves better. Simple unpredictability will no longer do.
The book has a remarkable, perhaps even unique, review of how our ideas about the brain have come to be what they are and how they have been influenced by the development of mathematics. These chapters can be used in many courses virtually independently of the rest of the book.
1. I suspect that the author's explanation of Bayes's theorem (p. 194-197) will be obscure to people who are not already familiar with it. I'd write it in the symmetric form, P(A|B)P(B) = P(B|A)P(A), and would use a simple, more natural example.
2. The book should have mentioned "Spikes: Exploring the Neural Code" (ed. F. Rieke and others), another very important book, after which sensory perception can no longer be viewed the same. While Dr. Glimcher's approach is based on Bayes's theorem and game theory, "Spikes" approaches perception by using Bayes's theorem and information theory. It will be every interesting to watch probability theory, game theory, and information theory mutate and merge into one mathematical theory of the brain (which so far does not exist; see my review of "The Handbook of Brain Theory and Neural Networks").
3. I was left wondering how stochastic differential equations (SDEs), widely used in economics, might be used to understand the brain. It is a little odd that the author has not even mentioned them, especially because they may help us model how a Nash equilibrium is reached by the brain. Without understanding the dynamics of this process and its implementation in the brain, this new approach will fail (as the author is acutely aware).
4. Frankly, I don't find the described experiments to be particularly convincing, but these experiments are very, very difficult to do, and very few people are doing them.
5. The author could have mentioned an interesting biography of Rene Descartes by R.A. Watson ("Cogito, Ergo Sum: The Life of Rene Descartes"). This biography is a bit strange, but still useful.
All in all, Paul Glimcher has written a superb book. This truly new conceptual approach will change our views on why we sometimes sit down and feel compelled to write such long reviews.
