Publisher Description
Drawing on a dazzlingly wide array of disciplines--physiology, neurology, psychology, anthropology, linguistics, and philosophy--Ian Glynn explains virtually every aspect of the workings of the brain, unlocking the mysteries of the mind.
Here are the mechanics of nerve messages; the functioning of sensory receptors; the processes by which the brain sees, tastes, and smells; the seats of language, memory, and emotions. Glynn writes with exceptional clarity and offers telling examples: to help explain vision, for instance, he discusses optical illusions as well as cases of patients who suffer disordered seeing through healthy eyes (such as the loss of the ability to recognize familiar faces). The breadth of Glynn's erudition is astonishing, as he ranges from parallel processing in computers to the specialization of different regions of the brain (illustrated with fascinating instances of the bizarre effects of localized brain damage). He explains the different types of memory (episodic and semantic, as well as short-term and implicit memory), traces the path through the brain of information leading to emotional responses, and engages in a discussion of language that takes in Noam Chomsky and Hawaiian pidgin. Moreover, for every subject Glynn addresses, he offers a thorough-going scientific history. For example, before discussing the evolution of the brain, he provides an account of the theory of evolution itself, from the writing and success of The Origin of Species to recent work on the fossil record, DNA, and RNA.
No other single volume has captured the full expanse of our knowledge of consciousness and the brain. A work of unequaled authority and eloquence, An Anatomy of Thought promises to be a new landmark of scientific writing.

How do we know? What do we think? How could a philosophical problem--"the mind-body problem," say--induce a headache? What can evolutionary theory, molecular biology, the history of medicine and experimental psychology tell us about the features of human consciousness, and (once again) how do we know? Glynn, a physician and Cambridge University professor, meticulously attempts to answer these questions and more, setting forth the results of all sorts of research relevant to our brains--from 19th-century dissections to Oliver Sacks-like case studies, work with monkeys and supercomputers, and the enduring puzzles of philosophy, which he rightly saves for near the end. After explaining evolution by natural selection and "clear away much dross," Glynn lays out the experiments and theories that have shown "how nerve cells can carry information about the body, how they can interact" and how sense organs work; demonstrates the "mixture of parallel and hierarchical organization" in our brains and "the striking localization of function within it"; considers where neuroscience is likely to go; and admits that, among the many fields of exciting research just ahead, "we can be least confident of progress explanation of our sensations and thoughts and feelings." Other recent explaining-the-brain books have sometimes advanced simplistic, or implausibly grand, claims about the nature and features of consciousness in general. Instead, Glynn offers a patient, informative, well-laid-out researcher's-eye view of what we have learned, how we figured it out and what we still don't know about neurons, senses, feelings, brains and minds.
