An Excellent Introductory Text for Understanding the Physical Basis of Cognition, December 6, 2009
The Brain-Shaped Mind: What the Brain Can Tell Us about the Mind by Naomi Goldblum is an excellent introductory book about the relationship between the mind and the brain. I am writing this review to encourage anyone interested in gaining basic knowledge about the brain-mind relationship to read this book. I read this book for my Introductory Neuroscience class at Georgia Tech, and I found it extremely helpful in explaining higher level processing of physical concepts in the brain. Even with no previous neuroscience knowledge, it is extremely easy to comprehend and absorb the information presented in this book because the author uses simple and effective examples to make her point. Unlike most books that stop after explain the positive aspects of a theory, this book provides the criticisms that are present. By presenting both sides of the argument, the author gives the readers an opportunity to choose to agree with or against the proposed theory.
Style and Structure:
The book is divided into twelve chapters, each of which will be summarized and discussed below. Each chapter in the book is additionally subdivided into smaller sections that provide a easy understanding of each subtopic. The author also provides simplified images that explain the basic concepts such as neuron structure, neurotrasmission from the presynaptic cell to the postsynaptic cell, etc. Instead of summarizing in detail what the author discusses in the book, I will provide the questions to which the author tries to provide answers through the course of the book.
The author discusses the following question in the book:
Chapter 1 - Introduction
(1) How are the mind and the brain related?
(2) How are the connectionist explanations different from other explanations of mental processes?
(3) Is the mind similar to the internet?
Chapter 2 - What the Brain Cannot Tell Us about the Mind
(1) Will scientists ever be able to read our minds?
(2) In what ways are the minds of different people different, and in what ways are they similar?
Chapter 3 - How Neurons form Networks
(1) How is the brain put together so as to serve as the basis for our mental functions?
(2) What physical connections allow us to form mental associations of things around us?
(3) What physical bases of change are constituted of learning?
Chapter 4 - Theories and Models of How the Mind Functions
(1) What is the difference between a theory and a model?
(2) What previous models were used to explain the organization of our knowledge?
(3) How can computers help us understand how our brain works even though our brains do not work like a computer?
Chapter 5 - What Are Connectionist Networks?
(1) What is the connectionist theory?
(2) How do we put things into categories (i.e. dogs vs. cats)?
(3) How do we know what we are looking at is what it is?
(4) How are all things we know about a topic connected to each other, and how are they retrieved when needed?
Chapter 6 - How Our Networks Learn
(1) How are the connections discussed in chapter five formed in the first place?
(2) How do children learn the difference between various things (i.e. cats and dogs)?
(3) Why do children call all four legged animals one thing at the beginning?
(4) How does this later grow into the capacity to differentiate between various kinds of dog and even individual dogs?
Chapter 7 - Connecting the Networks: How Different Thing are Related
(1) How do we know that various concepts are related to each other (i.e. salt and pepper, mother and father)?
(2) How do we go beyond the obvious relations between concepts (i.e. knowing wolf-hound is a dog, and forming a relationship between cats and dogs rather than cats and tigers)?
Chapter 8 - Evidence for Connectionist Models
(1) What experimental evidence is there for the connectionist models?
Chapter 9 - Two Different Types of Memory
(1) How we remember things for a long time vs. a short period of time?
(2) How do we remember to do a task, and after we do it, that we preformed a task?
Chapter 10 - Coping with Disaster
(1) What happens to functioning of the brain after a stroke, head injuries, and degenerative diseases such as Alzheimer's.
(2) How can brain regain normal brain function even if the brain damage itself cannot be repaired?
Chapter 11 - Practical Implications
(1) Are there ways to improve our daily mental functions using this knowledge?
(2) What other ways can this knowledge be used?
Chapter 12 - Criticism of connectionist theory
(1) What are the major criticisms of connectionist theory?
(2) What are the reasons these criticisms are wrong?
In the introduction, the author discusses that the relationship between the mind and brain, the author notifies the readers that consciousness and emotion will not be discussed in the scope of this book because the the connectionist theory that the book focuses on has not been used to describe these concepts. Instead, this book focuses on cognitive human functions (such as "classifying things into categories, speaking, understanding speech, and solving problems"). The meat of the book is the discussion of how the cellular level connectivity can explain cognitive functions of a brain. The gist of the connectionist theory is as follows: this theory considers the mental and behavioral phenomena as a result of interconnected networks of simple units that are working in parallel. The author uses animal categories to describe how people learn to form categories in the brain, and how to recall information from these categories in the brain. There are several computer models that are presented as evidence of the theory. For example, a computer has been able to "analyze a two-dimensional scenes, learn to talk, and learn past tense of words."
In addition, the author also discusses the two major type of memory: permanent and temporary memories. The author describes how the connectionist theory can and cannot explain these theories. For example, the author suggest that two different connectionist theories need to be used to describe these two type of memory. The differences between the models is as follows: "the two types of memories are stored in two different parts of the the brain, with different connections between the units" and "each general fact is distributed over all he neurons of a particular network, while temporary memories are stored locally". These differences need the models that describe them to be distinct. After discussing memory, they author discusses the practical implications of this information. This section discusses how students can study better, how teachers can teach better, and how we can get rid of unhealthy habits. The author finally concludes the book by discussing the criticisms (representationalist's criticism, and the nonscientific criticism) and how those criticisms are wrong.
Critique:
The author does an exquisite job of organizing the book in such a way that even those with no prior neuroscience knowledge can grasp the concepts explain throughout the book. For example, the author presents a clear scope of the book right in the introduction such that the reader knows exactly what the author plans to discuss and not discuss in the book. Then, the author continues to discuss the limitations of the concept of how the brain can describe the mind. She then discusses the structure of neurons, how they normally connect with each other, and how the plasticity of the brain arises from the axon connections to dendrites. After she has present this background, she then introduces the connectionist theory and the support for it. She also discusses the future implications of it as well as the criticism of it. This well planned and structured book provides the readers the basic information pertaining to the affect of neural connections on the cognitive capabilities of a human.
I personally found the latter part of the book extremely interesting and useful. Especially the chapter on the different types of memory, and the future implications chapter which discusses how to learn and teach better. As a student myself, I found the suggestions and study tips new and interesting. For example, the author suggests that study one topic for a short time and spend some time thinking about how that information connects to the information that is already in your head. Afterwards, study a totally different topic so that the neural networks working on remembering the first topic have time to solidify the information. Additionally, I found the how to better teach very useful for my volunteering tutoring of K-12 kids.
I highly recommend this book for anyone who is interested in neuroscience of cognition because it will provide you with enough information to intrigue but not overwhelm you. You will be able to use this book as a stepping stone to any other neuroscience book about cognition. Using the basics that you gathered from this book, you can delve in the plethora of neuroscience books that are present.
