The Soul in the Brain: The Cerebral Basis of Language, Art, and Belief Review

The Soul in the Brain: The Cerebral Basis of Language, Art, and Belief
Average Reviews:

(More customer reviews)
After a lifetime studying epilepsy and other neurological disorders, Michael Trimble has taken his considerable experience and used it as a means to explore how we become poets, prophets, or madmen (or all of the above). Those interested in the work of Oliver Sacks, Antonio Damasio, and V.S. Ramachandran will welcome this highly interesting volume. Trimble is Professor of Behavioral Neurology at the Institute of Neurology, University of London. His work has concentrated on the study of epilepsy but he has also edited an excellent and comprehensive volume entitled Biological Psychiatry (1996). His understanding of broad issues in neuropsychiatry is second to none. But what distinguishes The Soul in the Brain from Trimble's previous work is its focus on topics important to all of us. As he writes "The main theme of this book is the cerebral representations of emotional experiences that relate to music and religion and associated activities such as poetry" (53).
Trimble does a superb job reviewing loads of material and highlighting those pieces most relevant to the issues at hand. Here is a neurologist with a longstanding and passionate commitment to understanding all things human. Trimble's expressed admiration of William James, Freud, and John Hughlings Jackson confirm his desire to bring the field variously entitled neuropsychiatry or behavioral neurology to bear upon vital aspects of human experience.
The Soul in the Brain reviews such varied topics as poetry and religiosity, music and madness. Trimble highlights the cerebral mechanisms that contribute to such aptitudes. He demonstrates a genuine appreciation for these topics and for the disciplines that have traditionally sought to understand them. Trimble is not militant in his scientism. Concerning religion, for instance, he writes "Profane man is a descendant of H. religiosus, and he cannot wipe out his own history" (19). Not by simplifying or reducing the phenomena at hand will we come to an understanding but through a systematic revelation of underlying mechanisms we can gain greater clarity.
Of particular interest is the consideration of the right cerebral hemisphere and its relation to language, a topic Trimble feels has been neglected in the past. While Broca's and Wernicke's areas (the main regions associated with language) are typically located in the left hemisphere, other critical aspects of language including our abilities to work with metaphor, prosody, and tone probably derive from the right hemisphere's special capabilities.
Trimble's writing is clear and competent with some literary flourishes occasioned, no doubt, by his regard for poetry. In my opinion, the volume could have used a bit more editing, it felt `uneven' in numerous places. Several times while reading The Soul in the Brain I wished Trimble would have abbreviated some material and elaborated elsewhere. Most importantly, I wish he had discussed the relationship between temporal lobe epilepsy and religion at even greater length. Trimble devoted a chapter to this topic but given his expertise and the number of times I came across his name while reading about temporal lobe epilepsy elsewhere I had hoped for an even lengthier analysis. Those specifically interested in temporal lobe epilepsy would do well to read this volume but ought to read Eve LaPlante's excellent book Seized (1993) also.
The scope of the book is vast and in spite of this ambitious scope Trimble manages to synthesize most of the material he relates. Without any grand unifying theories to help us adequately combine biological and social insights books, like this one, that attempt to bring together diverse fields necessarily feel a bit scattered. This is less an insufficiency than a demonstration of bold vision and the desire to bring together fields that have previously allowed themselves to pass like ships in the night.

In this provocative study, Michael R. Trimble, M.D., tackles the interrelationship between brain function, language, art -- especially music and poetry -- and religion. By examining the breakdown of language in several neuropsychiatric disorders, neuroscientists have identified brain circuits that are involved with metaphor, poetry, music, and religious experiences. Drawing on this body of evidence, Trimble argues that religious experiences and beliefs are explicable biologically and relate to brain function, especially of the nondominant hemisphere.Inspired by the writings and reflections of his patients -- many of whom have epilepsy, psychosis, or affective disorders -- Trimble asks how the human species, so enamored of its own logic and critical facilities, has held from the dawn of civilization strong religious beliefs and a reverence for the arts. He explores topics such as the phenomena of hypergraphia and hyper-religiosity, how religious experiences and poetic expression are neurologically linked with our capacity to respond to music, and how neuropsychiatric disorders influence behaviors related to artistic expression and religiosity by disturbing brain function.With the sensitivity of a dedicated doctor and the curiosity of an accomplished scholar, Trimble offers an insightful analysis of how the study of people with paradigmatical neuropsychiatric conditions can be the cornerstone to unraveling some of the mysteries of the cerebral representations of our highest cultural experiences.

In the Eye of the Beholder: The Science of Face Perception Review

In the Eye of the Beholder: The Science of Face Perception
Average Reviews:

Authors Bruce and Young introduce aspects of the science of perception with reference to works of art. The book is a delight to read, and almost as much fun to browse, because the numerous images lead the browser to puzzle over the demonstrated twists of perception. The authors take appropriate, detailed steps in explaining the physical and psychological path of seeing. Additionally, they show us the importance of totally contemporary, computer tools used in the exploration of human perception.
I found In the Eye of the Beholder in the library, read it almost without putting it down, and had to buy a copy for myself. I will certainly be showing it to my students in drawing and painting.

The Creating Brain: The Neuroscience of Genius Review

The Creating Brain: The Neuroscience of Genius
Average Reviews:

(More customer reviews)
It is accurate to say that there has been more creative energy released in the last twenty-five years than any than the last twenty-five hundred. This is due not only to the number of people that are actually alive now, but also to the vast amount of knowledge that is readily available. Modern technology is responsible for the availability of this knowledge, and the technology itself was the result of human creativity and ingenuity. In addition, creative people can now communicate in ways they could not before, thanks to the rise of the Internet. Further, innovation has been strongly encouraged, not primarily by educational institutions and hierarchies, but by the business community. This is an interesting development, and one that shows every indication of continuing. The academy, which used to be considered a refugee camp for the creative mind, is no longer a place where one can pursue and develop original ideas without extreme difficulty.
In this highly interesting book, the author acknowledges that the environment is important in nurturing creativity, but she also wants to understand what mechanisms in the brain are responsible for it. An understanding of these mechanisms is extremely important, for it could point the way to better methods of enhancing creativity, either by using pharmaceuticals, with techniques from genetic engineering, or possibly with radical changes in the environment. The author is a neuroscientist, and not a philosopher, and so her analysis is based more on what is observed in the laboratory, and not mere speculations from the armchair. Her goal is to obtain a neuroscience of creativity, which considering the paucity of research in this area, is a goal that one hopes she (and other researchers) will succeed in reaching.
One of the first issues that the author addresses in the book is the relation (if any) between intelligence and creativity. Reviewing the history of the study between these two notions, and noting creative people have been equated with "geniuses", she concludes that, in general, one can conclude that a certain level of intelligence is needed to make original contributions, one needs another faculty of the brain in order to do so. It is not clear from this discussion whether she believes that this entails a modular view of the brain, i.e. one in which the brain consists of specialized modules for various tasks, one of these modules being for tasks requiring creativity.
The author is also careful to note that originality, creativity, or novelty are concepts that are dependent on the context in which ideas arise and in the perceived utility of these ideas. In this regard, she discusses the work of the psychologist Mihaly Csikszentmihalyi, who believed in the existence of "true creativity". As summarized by the author, Csikszentmihalyi held that creativity should be understood in terms of the relationship between a `domain', which is a particular area of knowledge; a `field' that is a collection of experts in the domain, and a `person' who actually introduces novel ideas into the domain under the auspices of the field. Motivated by these considerations, the author holds that creativity must involve originality, utility, and must lead to product of some kind. These requirements, at least on the surface, are reasonable, but there are difficulties that arise when one attempts to check them for a particular idea or concept. One issue that immediately arises in this regard is attempting to check whether indeed the concept or creation is indeed novel, or whether it was actually contained in prior ideas or creations. The issue of whether an idea was actually contained in prior ones comes up quite frequently in the field of automated mathematical discovery, which seeks to emulate, in a machine, human creative mathematical ability. Because of the deductive nature of mathematics, the progression of ideas must follow logically from those in prior ones, i.e. in the premises. But the "new" ideas must be different in some sense from the ones that they are logically derived from. It can be become very debatable whether these ideas were indeed original, or whether they were merely "contained in the premises."
The book would not be complete of course if the author did not discuss in detail her ideas on the neuroscience behind creativity. For the general reader, she includes some elementary discussion on brain anatomy as a warm-up. In her brief treatment of the functions of the brain she mentions the current debate as to the executive functions of the brain, i.e. whether there is a central "executive" in the brain that decides what changes are to occur. As an alternative to a central authority, the author mentions the view of the brain as being a `self-organizing' system. This is currently a popular view of the brain among physicists, and for the author it helps to explain what she calls "ordinary creativity." However, the author clearly believes that something else is needed to explain "extraordinary" creativity: unconscious processes such as the process of `free association.' The author refers to her experimental work on using neuroimaging technology to find out which areas of the brain are active during free association. Her work is also dependent on the notion of `episodic memory', which she characterizes as memory that is linked to the personal experiences of the individual. Her neuroimaging experiments indicated that the association cortex was active when the subject was engaging in random unconscious free association. She is careful to admit though that a lot more research is needed to find the neural basis behind extraordinary creativity, but her suspicion is that it involves making links between objects or concepts that were not linked before. These associative links "run wild" and create new connections, resulting in a disorganized mental state. This motivates her to study the connection between creativity and insanity, a topic that she also discusses at some length in the book, along with hints and exercises that individuals can use to enhance their creativity.

Principles of Frontal Lobe Function Review

Principles of Frontal Lobe Function
Average Reviews:

(More customer reviews)
Shortly after this book came out I took it with me to a conference. A fellow neurologist saw it and commented, "Great book, but you can't read it." Though there is a good deal of clinically relevant material here, the book is basically written from a cognitive neuroscience perspective and so some background in that discipline is necessary to comprehend the material. The book is a yeasty mix of theoretical and experimental work in these 34 chapters, often with overlapping but different, and sometimes conflicting, perspectives on the same phenomena, on what was once the terra incognita of the human brain. There is still a great deal of mystery and controversy over how the frontal lobes work, but we have come a long way since the story of Phineas Gage, and the contributors to this book have been amongst the pioneers. Definitely the premiere currently available book on the frontal lobes.

Principles of Frontal Lobe Function provides a comprehensive review of historical and current research on the functions of the frontal lobes and frontal systems of the brain.The content covers frontal lobe functions from birth to old age, from biochemistry and anatomy to rehabilitation, from normal to disrupted function.Two introductory chapters guide, in different ways, reading of subsequent chapters.Following are a number of chapters dealing with basic science- neuroanatomy and neurochemistry. The various theoretical positions proposed reflect the diversity of approaches to the same fundamental question about the role of the frontal lobes.Some chapters deal with broad, salient issues such as functional heterogeneity versus homogeneity, while others narrow their focus on specific functions like motor control, language, memory and attention, executive functioning, and emotional and social behavior.The book concludes with chapters on applied clinical research such as frontal lobe pathology in neurological diseases and disorders, stroke, and traumatic brain injury, as well as strategies for neurorehabilitation. This book is intended to be a standard reference work on the frontal lobes for researchers, clinicians, and students in the fields of neurology, neuroscience, psychiatry, psychology, and health care.

A Brief Tour of Human Consciousness: From Impostor Poodles to Purple Numbers Review

A Brief Tour of Human Consciousness: From Impostor Poodles to Purple Numbers
Average Reviews:

(More customer reviews)
I attended the 2005 Skeptics Society conference on Brain, Mind, and Consciousness at Caltech, where Ramachandran had been scheduled to speak but was unable to do so because of a family emergency. Although I was not previously familiar with his work, the description led me to believe he was a speaker I would be interested in hearing, and this book, which I purchased at the conference, provides a strong case for that. I've long had an interest in philosophy of mind and cognitive science, and minored in cognitive science in my Ph.D. studies (never completed) at the University of Arizona. I've been out of academia for 11 years now, and apart from reading occasional works like Daniel Dennett's Consciousness Explained and Freedom Evolves, I've not been keeping close tabs on the field. The conference and this book were quite a pleasure--it is clear that there have been some significant developments over the last decade.
It is hard to believe that there are still people who think the brain is little more than a radio receiver, a set of mechanical controls for a disembodied spirit to manipulate the body. Ramachandran's book--like the case studies of Oliver Sacks and A.N. Luria--shows how wrongheaded that view is.
This is a thin (112 pages of text, 45 pages of notes), very accessible and entertaining book. If you enjoy the works of Sacks and Luria, you are likely to enjoy this as well. This is not a collection of case studies, though there are some descriptions of particular patients--it is written from a higher elevation, bringing together recent results, explaining unusual phenomena, and speculating about how those phenomena may tie in to a further understanding of the details of the brain's function.
The book came from Ramachandran's BBC Reith lectures, so it is for a popular audience, with the notes providing some more underlying detail. There are five chapters, each dealing with a single topic. The first chapter is about amputees who experience pain in their "phantom limbs" and how the parts of the brain which had been devoted to the now-absent limbs can become mapped to still-present parts of the body which are handled by physically proximate parts of the brain. For example, a patient whose left arm had been amputated could feel contact to the nonexistent fingers of his left hand from touches to parts of his face or upper arm. Ramachandran then uses this remapping phenomenon to speculate about the causes of Capgras' syndrome (where a patient believes people he knows have been replaced withimpostors), synesthesia, and pain asymbolia, where a patient responds to pain stimulus with laughter.
The second chapter is about vision, and specifically about the phenomena of blindsight (where a person has no experience of seeing, but at an unconscious level does see), hemisphere neglect, and mirror agnosia. In this chapter Ramachandran discusses "mirror neurons," neurons found in monkeys which activate when a monkey performs some task, but also when the monkey sees another monkey perform the same task.
The third chapter, "The Artful Brain," is the most speculative, and provides Ramachandran's suggested ten "universal laws of art," which he offers as features we find aesthetically pleasing in art, and discusses some reasons why those features might be pleasing to the brain.
The fourth chapter deals in more detail with synesthesia, the perception of stimuli with multiple senses, such as experiencing colors corresponding with sounds or numbers. He links this to cross-activation of sites in the brain (similar to his discussion in the first chapter), points out some similar phenomena that most people share (such as a tendency to associate certain kinds of abstract shapes with certain sounds or names), and speculates that such associations may have paved the way for the evolution of language from non-verbal communication.
The fifth and final chapter is titled "Neuroscience--The New Philosophy." Ramachandran discusses how some of the phenomena of neuroscience might bear on questions from philosophy of mind about qualia, free will, and self-awareness. The chapter doesn't get very deep into any of these philosophical issues, but it's clear that more has been learned in the last few decades of neuroscience than in the last few millenia of philosophy.
I highly recommend this book as an introduction to these topics.

How Genes Influence Behavior Review

How Genes Influence Behavior
Average Reviews:

(More customer reviews)
One would expect an introductory textbook by these three scientists to be good, and it is. It covers behavioural and molecular methods, using examples from the authors' own work in psychiatric genetics. The field is put in historical context, with the false turnings explored, as well as the major breakthroughs. The authors take us on a journey through family, adoption and twin studies, on to the history of molecular psychiatric genetics, starting with the early, and usually unreplicated, linkage studies, through genome wide association studies and animal models using rodents and drosophila. Concepts are explained with a minimum of technical and statistical detail, making the book accessible to a wide readership. What sets this book apart from others on this topic are the personal and often witty accounts of doing research. Kendler's anecdote of a family study of schizophrenia in Ireland is particularly engaging, including an encounter with an elderly grandmother who expressed indignation that he should be driving around all over the place interviewing people to find out if mental illness ran in families. "'Why everybody knows that! Take the O'Donnells for example. They are as mad as can be and it goes back generations." (p. 12). One also gets a sense of the hard graft involved in doing research in this area: Kendler estimated that his study took 18 person years just to gather the data, and evidently required persistence and a willingness to work heroically antisocial hours by the research team.
Anyone contemplating a research career in molecular genetics would do well to read the paragraph on p 34-35 debunking popular assumptions about life in the laboratory: "A combination of intelligence and technology applied to taxing but interesting biological problems leads to ground-breaking discoveries that could cure disease or change our understanding of the universe." Well, no. The work is dull, repetitive, and usually unsuccessful. And if after years of work you do find something interesting, your laboratory head will ask: "Why is this finding wrong?". In fact, I suspect only really good laboratory heads do that - the bad ones rush gleefully into print, which is why the field is littered with nonreplicable findings. But as Flint et al point out, you need to ask it because it's embarrassing to publishing something that is wrong, your peers will do their best to find flaws in the work, and, most importantly, "it's only by publishing findings that are robust to any possible criticism that we'll make any progress". A refreshingly old-fashioned take on the scientific process that is all-too-often forgotten in the current climate where we're all encouraged to publish as much as we possibly can, and where a dramatic but non-replicable result may get you two papers in a high-impact journal: one for the original finding, and the other for the failure to replicate.

How important are genetic influences on behavior?How many genes influence an individual behavior, and how much influence does a single gene have? How do genes interact with the environment to influence the development of behavioral traits?What are the differences between humans and 'simpler' organisms when it comes to the genetic control of behavior? How Genes Influence Behavior is a unique introduction to behavioral genetics, which combines conceptual rigor with accessibility to answer questions such as these--answers that carry important implications for the nature of who we are. Offering unparalleled insights into how behavioral genetics is probed through real-world research, it considers evidence from humans and the major model organisms of mouse, fruit-fly and nematode worm to demonstrate how much of our current understanding of the genetic basis of human behavior stems from our exploration of other animals. Further, it uses these studies to connect the key themes of the book--the nature of gene action, and the inter-relationship of genetic and environmental influences on behavior-across organisms, highlighting key commonalities and differences.The book also shows the major impact that neurobiology is having on our understanding of the field, to give a true depiction of behavioral genetics in the 21st century. However, care is taken throughout not to overwhelm the reader with scientific detail. Instead, the authors make the book fun to read without sacrificing accuracy or devaluing the complexity of the subject matter: they 'personalize' the science, mixing more standard narrative with biographical details to make the subject come alive. With the media filled with talk of the discovery of genes 'for' an array of human behaviors, there has never been a more pressing need for today's students--tomorrow's researchers--to be equipped with a clear, balanced view of the field. How Genes Influence Behavior is the perfect guide for all students, delivered in the words of three researchers who have witnessed first-hand the emergence of this fascinating field, and whose own investigations have been central to our current understanding of it.Online Resource CentreFor Instructors* Figures from the book, available to downloadFor students* Hyperlinks to primary literature cited in the text

Inner Vision: An Exploration of Art and the Brain Review

Inner Vision: An Exploration of Art and the Brain
Average Reviews:

(More customer reviews)
as someone with a doctorate in psychology who has retired to a life of intensive painting, i can say this book falls short in its fundamental premise: if we can identify a distinct visual capability in the brain, that capability forms the basis for visual esthetic judgments. that argument unfortunately goes nowhere, and the result is a thin book with its substantive content spread even thinner.
zeki's argument is roughly that the mind is an active creator of visual experience; that we create visual experience using a variety of "modular" cerebral functions (specific neighborhoods of the brain that detect edges, analyze movement, perceive color, recognize faces); and that art works which "appeal" to these modular capabilities provide the foundation for art. claims that art that becomes "great" if the mind is presented with ambiguous or multiple interpretations, provoking it to "actively create" varied interpretations from the work in view. in this way zeki hopes to reason his way toward a "neurological esthetics," a biologically based prescription of what is beautiful or compelling art.
well, where to begin ... because a brain function is invoked by a stimulus does not make it interesting or great; my review invokes your language capabilities, but that doesn't make my words poetry. a painting does not succeed by creating a variety of specific but competing interpretations, as zeki claims, but by reframing awareness into a realm where the mundane categorizations necessary for behavior are stretched by the exercise of the senses. what counts as beautiful cannot be determined from the quantitative activity of different brain regions. what counts as beautiful depends heavily on cultural expectations, not on physiology ... on and on the objections roll.
in the end, zeki's argument is highly parochial. his examples come from the "edge detection" art of the supremacists or the cubists; the "color perception" art of the fauves, the "movement perception" art of calder, and so on -- simplistic art for simplistic art theories. (someone should ask, where are the edges in monet or turner, the color in kline or velazquez, the movement in vermeer or van dyck?) on the philosophical side, zeki seems willing to cite plato or hegel as straw men to knock down, but seems completely unaware of the many philosophical or social psychological theorists who could enrich his "active construction" view of visual perception. finally, zeki seems not to have had a personal colloquy with practicing artists, who could disabuse him of his naive reading of western art and its traditions.
psychologists will find this book to be unexpectedly thin on the facts of recent neural research and cognitive function, and lacking in philosophical depth. artists will look at zeki's simplistic reading of art and art history, shrug and wonder, what is this guy talking about?
