Rezension

"The book covers wide-ranging ground--indeed, it passes for a computer science or philosophy textbook in places--but it does so in a consistently lucid and engaging fashion." (CHOICE, December 2009) "The authors provide a cogent set of ideas regarding a kind of brain functional architecture that could serve as a thought-provoking alternative to that envisioned by current dogma. If one is seriously concerned with understanding and investigating the brain and how it operates, taking the time to absorb the ideas conveyed in this book is likely to be time well spent." (PsycCRITIQUES, November 2009) "Along with a light complement of fascinating psychological case studies of representations of space and time, and a heavy set of polemical sideswipes at neuroscientists and their hapless computational fellow travelers, this book has the simple goal of persuading us of the importance of a particular information processing mechanism that it claims does not currently occupy center stage." (Nature Neuroscience, October 2009)

Back cover copy

Memory and the Computational Brain spans the fields of cognitive science, linguistics, psychology, neuroscience, and education, to suggest new perspectives on the way we consider learning mechanisms in the brain. Gallistel and King propose that the architecture of the brain is structured precisely for learning and for memory, and that the concept of an addressable read/write memory mechanism should be integrated into the foundations of neuroscience. They argue that the field of neuroscience can and should benefit from the recent advances of cognitive science and the development of information theory over the recent decades. Based on three lectures given by Randy Gallistel in the prestigious Blackwell-Maryland Lectures in Language and Cognition, the text has been significantly revised and expanded with numerous interdisciplinary examples and models and reflects recent research to make it essential reading for both students and those working in the field.

Unpublished endorsement

"Any scientist seriously interested in how the brain does its work will find Gallistel and King's new book indispensable. It challenges modern dogma and does so in a clear and compelling manner." –Michael Gazzaniga, University of California, Santa Barbara "Gallistel and King present a provocative challenge to our current "standard model" of information processing in the brain. This book's ideas should be read and digested by both cognitive scientists and neuroscientists - anyone seriously interested in the biological or computational underpinnings of learning." –Joshua B. Tenenbaum, Massachusetts Institute of Technology "A lucid and convincing argument for a particular architecture for encoding information in the brain, based on some key notions of computational cognitive science, a significant contribution to neuroscience." –Aravind K. Joshi, University of Pennsylvania
