Oxford Companion to Consciousness ReviewThis is a remarkable selection of state-of-the-art, very readable articles on all aspects of the academic study of consciousness. (Thankfully, you will only find serious research here, no esoteric speculation.)
The editors did an excellent job of compiling an impressive list of relevant topics, finding the most prominent authors for the entries and making this book truly interdisciplinary by covering topics from different perspectives and disciplines (i.e., neuroscience, psychology, philosophy, ethology). They have also made sure that the entries are very readable so as to be informative for newcomers to the area and experts alike. Given the breadth of topics and the interdisciplinary nature of the book, this is an extremely valuable resource for students and more senior researchers alike. If you want to know where consciousness research is at today, where it came from, and where it is going, this is THE book for you!
The only complaint I have is the lack of an index, but apart from this technical detail, this is a truly marvelous book, which I highly recommend.Oxford Companion to Consciousness OverviewConsciousness is undoubtedly one of the last remaining scientific mysteries and hence one of the greatest contemporary scientific challenges. How does the brain's activity result in the rich phenomenology that characterizes our waking life? Are animals conscious? Why did consciousness evolve? How does science proceed to answer such questions? Can we define what consciousness is? Can we measure it? Can we use experimental results to further our understanding of disorders of consciousness, such as those seen in schizophrenia, delirium, or altered states of consciousness? These questions are at the heart of contemporary research in the domain. Answering them requires a fundamentally interdisciplinary approach that engages not only philosophers, but also neuroscientists and psychologists in a joint effort to develop novel approaches that reflect both the stunning recent advances in imaging methods as well as the continuing refinement of our concepts of consciousness. In this light, theOxford Companion to Consciousness is the most complete authoritative survey of contemporary research on consciousness. Five years in the making and including over 250 concise entries written by leaders in the field, the volume covers both fundamental knowledge as well as more recent advances in this rapidly changing domain. Structured as an easy-to-use dictionary and extensively cross-referenced, the Companionoffers contributions from philosophy of mind to neuroscience, from experimental psychology to clinical findings, so reflecting the profoundly interdisciplinary nature of the domain. Particular care has been taken to ensure that each of the entries is accessible to the general reader and that the overall volume represents a comprehensive snapshot of the contemporary study of consciousness. The result is a unique compendium that will prove indispensable to anyone interested in consciousness, from beginning students wishing to clarify a concept to professional consciousness researchers looking for the best characterization of a particular phenomenon.

This Is Your Brain on Music: The Science of a Human Obsession ReviewThere are questions that are too big for science; are there gods, for instance, or what is love? And maybe we will never fully find out scientifically why music does what it does and why we care about it so. But for many reasons, music ought to be a profitable subject for scientific enquiry. It is, as Pythagoras knew, an activity strongly rooted in mathematics, and the physics of music is fairly well understood. It is as universal as language; all human cultures have some sort of music, indicating it does something indispensable. And we are increasingly able to figure out, with our sophisticated brain imaging gadgets, what brains do when they hear or think about music. The neuroscience of music is the area of expertise of Daniel J. Levitin, and he writes of it in _This Is Your Brain on Music: The Science of a Human Obsession_ (Dutton), a fascinating account of current music psychology. Levitin has produced a book wonderfully accessible to lay readers, since although he is an academic (he runs the Laboratory for Musical Perception, Cognition, and Expertise at McGill University), before he became a scientist, he had been a performing musician, sound engineer, and record producer, working with names like Steely Dan and Blue Oyster Cult. He does pull examples from Bach and Beethoven, but he is obviously more comfortable citing universally-known tunes like "Happy Birthday to You", "Somewhere Over the Rainbow", or "Stairway to Heaven". (Readers whose tastes range in previous epochs will possibly be surprised at the sophistication modern popular musicians have displayed.) Levitin has a good sense of humor and is a genial explainer.
He starts out with a forty page first chapter "What is Music?", which is as good a short explanation of key concepts as tone, scale, fifths, and timbre as anyone could want, and is a fine foundation for all that comes after, a collection of scientific lore and tidbits from all over. For instance, even if you are not a musician, you have a huge store of tunes in your memory. You may not have perfect pitch, the ability to know that an A flat is an A flat as soon as you hear it, but Levitin's own research has provided surprising evidence that your sense of pitch, even if you are not a musician, is really quite good. Subjects who were asked to sing a song from memory got the absolute pitch just right, or very close; they did the same with the song's tempo. There are differences in the brains of musicians and nonmusicians. The corpus callosum, the mass of fibers that connects the right brain hemisphere to the left, is larger in musicians, and is especially larger in those that started music training early. The overall lesson here, though, is that we are all musical, even if we are not musicians, and so non-expert musical brains are really very similar to expert ones. There are descriptions here of surprising research that makes clear how truly ready our brains are to incorporate musical experience. Fetuses in the last three months of gestation, for instance, can hear music within the womb, along with other outside and inside noises. Experiments have shown that if you repeatedly play a song into the womb, and then make sure the child does not hear it again after birth until it is one year old, and then play the music again, the infant will prefer hearing the womb-music rather than completely novel music. This was true whether the experimental music was Vivaldi or the Backstreet Boys.
Levitin certainly has connections; he tells of discussions with Francis Crick about themes in this book, as well as with Joni Mitchell. The final chapter, "The Music Instinct", is a response to cognitive scientist Steven Pinker, who spoke at a 1997 convention of researchers in music perception and cognition. Pinker took the dismissive stance that music was "auditory cheesecake", tickling the parts of the brain that were really for the important functions of language and (unlike language) useless as a force in human evolution. It is not surprising that Levitin and his fellow researchers disagree. Darwin himself felt that musical tones were used in conveying emotion and that those who were able to expend energy in singing or playing were demonstrating biological and sexual fitness. Musical success does make for high numbers of opportunities for spreading one's genes (just ask Mick Jagger). Interest in music peaks in adolescence, indicating a role in sexual selection. Music has been around longer than agriculture, and there is no evidence that language actually preceded music in our species. It may have promoted the cognitive development that was harnessed for speech. Only in the past few hundred years did music become a spectator activity, but in the eons when it could have shaped our social evolution, it was a group activity that may have promoted group togetherness and synchrony. It is an engaging final argument that serves to emphasize the importance of all that the book has presented before, a demonstration that looking at an important human activity in a scientific way only increases our wonder and delight in the activity itself.This Is Your Brain on Music: The Science of a Human Obsession Overview

Cognitive Psychology ReviewI find this book to be terribly frustrating. I have only read a few chapters in this book (a great deal of that material several times) and concepts that this book introduces are just not clear. the abnormal psychology book that Sue Sue and Sue wrote is phenomenal, every key concept is clearly defined, and it is immediately discussed and then supplemented with examples and extra information. With this Cognitive Psychology book I feel like every important concept is shrouded in fog. There are far too many examples and few terms are defined immediately and with accuracy. With this said, I would suggest this book for people that would like to supplement their reading, due to the massive amounts of examples in this book. For some, this book may be perfect, I just prefer a more direct approach that other psychology books offer.Cognitive Psychology OverviewThis coherent overview of cognitive psychology is organized in terms of themes that cut across topic areas. Written by well-known researchers, the book is completely current in describing ongoing controversies in research; it provides summaries of key experiments that distinguish between them; and it encourages the reader to think critically about current research and theories. The focus on the importance of physical and computational constraints on cognition is preserved throughout the book.

Matlab for Neuroscientists: An Introduction to Scientific Computing in Matlab ReviewI had no previous background in programming or computer science, but based on the reviews I bought this book as an introduction to learning Matlab because it was more specific to the field I'm in. I am REALLY surprised at the reviews that say this book is for beginners. I agree with the previous review that says the book starts off easy to understand, and then it feels like it leaves you on your own to figure out a lot of things.
For example, I was trying to complete the first project on my own and using only the commands covered in the previous chapters. I had to ask for help from friends and despite me telling them "I don't think I'm supposed to use that command because they haven't explained it yet" they still gave me other ways to write certain functions that weren't covered. Since I couldn't figure out how to integrate some of the previous material, I wrote the project program with commands that weren't covered by the book up to that point. It was pretty unsatisfying and discouraging. Not the book's fault that my friends didn't use what was taught, but it does lack some guidance for the projects.
My biggest complaint is that I can't find sample programs for the projects! I've checked the companion website and tried to buy the answer manual online, but you have to prove that you're a professor in order to buy it. Available answers would really help someone like me (who has ZERO intuition for programming) get started on projects and find more efficient ways of writing programs. It's not the advanced math or methods described that make this text hard to get through, which some reviewers are attributing to the bad reviews.
There are lots of comments that accompany the examples, a color insert, and a really helpful appendix that quickly reviews some matrix algebra. This seems like a good book for someone in neuroscience or psychology who already has some background in Matlab. But if you're just starting out, especially without any background in programming, this book will likely discourage you. Also, I could see how this book would be good for a beginning course because you've got a professor to guide you through the text. However, I'd recommend David Rosenbaum's "Matlab for Behavioral Scientists" for a beginning text if you're teaching yourself. After reading that book, I've looked back at this book and can understand everything much better.
Matlab for Neuroscientists: An Introduction to Scientific Computing in Matlab OverviewMatlab is the accepted standard for scientific computing, used globally in virtually all Neuroscience and Cognitive Psychology laboratories. For instance, SPM, the most used software for the analysis and manipulation of fMRI images in research and clinical practice is fully programmed in matlab, and its use of the possibility to allow for sophisticated software modules to be freely added to the software has established it as the by far dominant software in the field. Many universities now offer, or are beginning to offer matlab introductory courses in their neuroscience and psychology programs. Nevertheless, so far there hasn't been a textbook specific to this market, and the use of the plethora of existing engineering focused Matlab textbooks is notoriously difficult for teaching the package in those environments.This is the first comprehensive teaching resource and textbook for the teaching of Matlab in the Neurosciences and in Psychology.Matlab is unique in that it can be used to learn the entire empirical and experimental process, including stimulus generation, experimental control, data collection, data analysis and modeling.Thus a wide variety of computational problems can be addressed in a single programming environment.The idea is to empower advanced undergraduates and beginning graduate students by allowing them to design and implement their own analytical tools. As students advance in their research careers, they will have achieved the fluency required to understand and adapt more specialized tools as opposed to treating them as "black boxes".Virtually all computational approaches in the book are covered by using genuine experimental data that are either collected as part of the lab project or were collected in the labs of the authors, providing the casual student with the look and feel of real data. In some rare cases, published data from classical papers are used to illustrate important concepts, giving students a computational understanding of critically important research. The ability to effectively use computers in research is necessary in an academic environment that is increasingly focused on quantitative issues.Matlab represents an ideal language of scientific computing. It is based on powerful linear algebra structures which lend themselves to empirical problems on the one hand, while at the same time allowing the student to make rapid problem-oriented progress (particularly in terms of visualization of data points) without having to lose focus by worrying too much about memory allocation and other "plumbing" minutiae as would be required in other, more low-level programming languages such as C or C++. Currently, there are several books that provide introductions to Matlab that are either too generic and fundamental or too irrelevant for neuroscientists and cognitive psychologists who typically face a very circumscribed range of problems in data collection, data analysis and signal processing. Some non-book tutorials and primers that are in use in the community are typically out of date. Matlab versions are usually not backwards compatible. Many commands and functions used in older tutorials and primers, such as "flops" won't work in current versions of Matlab, necessitating a book that is timely and up-to-date.The complete lack of a relevant resource in this area, combined with a clearly felt need for such a text provided the primary and initial impetus for this project. The authors provide such a dearly needed resource adapting and pooling materials that developed for and used in highly rated courses involving the use of Matlab in Neuroscience at the University of Chicago.Two co-authors (PW and NH) have presented their respective work on teaching Matlab at national meetings and two of the co-authors (PW and MB) were awarded the coveted University of Chicago's Booth Prize for excellence in teaching these courses.
