This book is more related with question than answer. The authors focus on the success and the pit falls of the growing science of consciousness in a very elegant and explicit way. As neuroscientists, aware of the technological advance, they establish what the technology can do to uncover consciousness and what it can't do at the present time. In addition, they also comments on what is still needed in order to obtain more information about consciousness in live human beings. But most of all, they argue about the necessity of clarifying the definition of consciousness in order to lead to new discoveries.
The book could be divided in three parts. The first few chapters deal with basic concepts of the central nervous system from what a neuron is? to neurotransmitters, to the hypothesis of long-term potentiation as evidence of the physical existence of memory. In the middle, there are two excellent chapters on the problem with the diagnosis of dementia (Alzheimer's disease and squizophrenia) and how careful we have to be to establish generalization such as that when you get old you will be nuts, or is you find any of these symptoms your dealing with a squizophrenic. Then, the rest of the book is focus on consciousness, presented in a multidisciplinary approach. From artificial intelligent to philosophy.
Written for a general audience, From Brains to Consciousness is and excellent source to complement a text book on basic neuroscience in a way to arouse the curiosity and to debate fundamental things about being human with the students, in addition to break with the standard of learning facts.
