BEST OF THE BRAIN FROM SCIENTIFIC AMERICAN --- MIND, MATTER,
AND TOMORROW'S BRAIN edited by Floyd E. Bloom. Dana Press, 2007


SELECTED OUTLINE OF BOOK'S FACTS & IDEAS

    INTRODUCTION by Floyd E. Bloom (1-5)

      The study of the human brain and its disease remains one of the greatest scientific and philosophical challenges ever undertaken. The knowledge we have collected has become so plentiful and significant that it tends to intimidate novices and tempt the unaware into believing that the most important findings are behind us. In fact, the past accomplishments now allow us to pose better and still more interesting questions. (1)

      The discoveries that defined the 1990s — designated the "Decade of the Brain" by the Library of Congress and the National Institute of Mental Health — have given rise to findings in the 21st Century that span academic disciplines and have far-reaching implications. The articles in this book reflect the promise, excitement and intrigue in many areas since the official end of the Decade of the Brain. (1)

      This book begins with a section that reveals how researchers on the frontiers of brain science have come to focus on the biological mechanisms underling mental activity in normal, experimental or clinical conditions. The articles under the heading "MIND" deal with behavior, personality, and cognition. They refer to the "higher brain functions." (1)

      The second and largest part of the book has the heading "MATTER." This is because diseases of the brain often reveal the holes in our knowledge of the healthy brain. The illnesses that remain untreatable hold the greatest challenge for researchers. The articles in this section explain how scientists are reviewing the origins of the thought and emotional problems that characterize schizophrenia and depression. Also, they explain how the mental activities of the brain emerge from the brain's underlying biological organization. (1-2)

      "The pioneers of brain research named the components of the nervous system for both their appearance and their location. For example, the names of the major parts of the brain resulted from creative interpretations by early dissectors of the brain, attributing names to brain segments based on their appearances in the freshly dissected state --- "hippocampus" (shaped like the sea horse) or "amygdala" (shaped like the almond), "cerebrum" (the main brain) and "cerebellum" (the small brain). (3)

      Although the brain is a single, unique organ, it is more properly conceptualized as an assembly of interrelated neural systems that regulate their own and each other's activity in a dynamic, complex fashion largely through a chemical process among cells called "neurotransmission." The brain and spinal cord together constitute the central nervous system, or "CNS." The two cerebral hemispheres ["left brain" and "right brain"] make up the largest division of the brain. (3)

      Regions of the cortex are classified in several ways. The first category comprises the types of information processed, such as "sensory" (somatosensory, visual, auditory, and olfactory); "motor" (walking, reaching, writing); or "associational" (considered to underlie higher "cortical functions" such as abstract thought, memory, and consciousness). A second category turns to anatomical position in the brain, [such as] (frontal, temporal, parietal, and occipital). And a third focuses on the geometrical relationships between the size, shape, and density of neurons in the major cortical layers. (3-4)

    PART 1 — MIND (7-75)

      1) UNLEASHING CREATIVITY by Ulrich Kraft (9-19)

        Moments of brilliance arise from complex cognitive processes. Piece by piece, researchers are uncovering the secrets of creative thinking. (9)

        [1] It's not intellect (12-13)

          Insert = Steps to a creative mind-set (13)

            (1) Wonderment = Try to retain a spirit of discovery, a childlike curiosity about the world. Questions] understandings that others consider obvious.

            (2) Motivation = As soon as a spark of interest arises in something, follow it!

            (3) Intellectual courage = Strive to think outside accepted principles and habitual perspectives such as "We've always done it that way."

            (4) Relaxation = Take the time to daydream and ponder, because that is often when the best ideas arise. Look for ways to relax and consciously put them into practice.

        Today, creativity experts look for certain characteristics that people who excel at divergent thinking seem to exhibit, such as the following six examples:

          (1) Ideational fluency = The number of ideas, sentences and associatioins a person can think of when presented with a word.

          (2) Variety and flexibility =

          (3) Originality =

          (4) Elaboration =

          (5) Problem sensitivity =

BOOK'S DESCRIPTION & REVIEWS

    PUBLISHERS WEEKLY REVIEW = Well written and accessible to a general audience, these 21 articles from Scientific American since 1999 provide insight into our current state of knowledge about the human brain. Floyd, past president of the American Association for the Advancement of Science and former editor of its flagship journal, Science, is ideal to make this selection. In the first section, "Mind," about high-level brain functions, Nobel laureate Eric Kandel argues that we are now poised to turn "mind" from a philosophical concept into a scientific one.

    The next section, "Matter," deals primarily with disorders of the brain and how, for example, researchers hope to devise effective treatments and better understand the healthy brain. The final section, "Tomorrow's Brain," envisions a time when prosthetic devises might be controlled by thought alone, when artificial retinas are commonplace and when humans and machines merge into what could only be described as a new entity a future that may not be so far off. Miguel Nicoleli and John Chapin show how Belle, an owl monkey, working with a microwire array implanted on the surface of her brain, moves an artificial arm merely by thinking of making it move. There's much to stimulate the brain of any reader. 30 color illus. (June) Copyright ? Reed Business Information, a division of Reed Elsevier Inc. All rights reserved. From: Reed Elsevier Inc.

    LIBRARY JOURNAL REVIEW = Starred Review. Through the 1990s, neuroscience underwent a veritable revolution, thanks to the improved ability of health professionals to diagnose and treat ailments with more accuracy using advanced imaging techniques. Bloom, chair emeritus of the Department of Neuropharmacology at the Scripps Research Institute and a former editor of the journal Science, has compiled a remarkable volume of essays culled from the pages of Scientific American and Scientific American Mind that offer an outstanding overview of recent and emerging developments in the field since 1999.

    The first section, "Mind," explores consciousness via a series of essays that examine the human brain and creativity, the current outlook on Freudian theories, and how the brain gives rise to the human self. "Matter," the second section, investigates the specifics of the brain's biology and neurology, and includes articles on neuroplasticity as well as the neurobiology of schizophrenia, depression, and addiction. The final section, "Tomorrow's Brain," addresses upcoming puzzles and challenges in brain research. Highly recommended for all public and undergraduate college libraries.
