This is an excellent book, focusing on fMRI and PET, that goes over in detail methodology and applications. The methodology sections includes details on the underlying physiology (it's more complicated than just blood flow and 02 extraction)and critiques the commonly used subtraction method, preferring instead event-evoked studies. Going beyond the simplistic concepts of areas "lighting up" being "for" this or that cognitive function, there is coverage of network analysis. The methodology is obviously still in an early evolutionary phase, and each chapter has closing section on controversies and future directions. The application sections cover neuroimaging of attention, visual recognition, semantic, episodic and working memory, and language. There is good critical review of the literature here, and there is no tendency towards oversimplification of conflicting results. There is also a chapter on cognitive aging that I found particularly informative, showing how the elderly utilize different neural networks than younger people to perform various cognitive tasks. The book is about 400 pages and includes 22 color plates. This is a very rich and rapidly evolving research area, and I think this is a great intro book for clinicians in neurology, psychology and psychiatry, as well as neuroradiology, to get an appreciation of what just a few years ago was a science fiction concept...taking pictures of the mind as it thinks.
