Meaning In The Brain

Defending the superiority of evidence-based reasoning over religious faith and philosophical thought experiments, Thagard argues that minds are brains and that reality is what science can discover. Brains come to know reality through a combination of perception and reasoning. Just as important, our brains evaluate aspects of reality through emotions that can produce both good and bad decisions. Our cognitive and emotional abilities allow us to understand reality, decide effectively, act morally, and pursue the vital needs of love, work, and play. Wisdom consists of knowing what matters, why it matters, and how to achieve it."--Jacket.

The brain ... There is no other part of the human anatomy that is so intriguing. How does it develop and function and why does it sometimes, tragically, degenerate? The answers are complex. In Discovering the Brain, science writer Sandra Ackerman cuts through the complexity to bring this vital topic to the public. The 1990s were declared the "Decade of the Brain" by former President Bush, and the neuroscience community responded with a host of new investigations and conferences. Discovering the Brain is based on the Institute of Medicine conference, Decade of the Brain: Frontiers in Neuroscience and Brain Research. Discovering the Brain is a "field guide" to the brainâ€"an easy-to-read discussion of the brain's physical structure and where functions such as language and music appreciation lie. Ackerman examines: How electrical and chemical signals are conveyed in the brain. The mechanisms by which we see, hear, think, and pay attentionâ€"and how a "gut feeling" actually originates in the brain. Learning and memory retention, including parallels to computer memory and what they might tell us about our own mental capacity. Development of the brain throughout the life span, with a look at the aging brain. Ackerman provides an enlightening chapter on the connection between the brain's physical condition and various mental disorders and notes what progress can realistically be made toward the prevention and treatment of stroke and other ailments. Finally, she explores the potential for major advances during the "Decade of the Brain," with a look at medical imaging techniquesâ€"what various technologies can and cannot tell usâ€"and how the public and private sectors can contribute to continued advances in neuroscience. This highly readable volume will provide the public and policymakersâ€"and many scientists as wellâ€"with a helpful guide to understanding the many discoveries that are sure to be announced throughout the "Decade of the Brain."

An argument that the meaning of written or auditory linguistic signals is not derived from the input but results from the brain's internal construction process. When we read a text or listen to speech, meaning seems to be given to us instantaneously, as if it were part of the input. In Meaning in the Brain, Giosuè Baggio explains that this is an illusion created by the tremendous speed at which sensory systems and systems for meaning and grammar operate in the brain. Meaning, Baggio argues, is not derived from input but results from the brain's internal construction process. With this book, Baggio offers the first integrated, multilevel theory of semantics in the brain, describing how meaning is generated during language comprehension, production, and acquisition. Baggio's theory draws on recent advances in formal semantics and pragmatics, including vector-space semantics, discourse representation theory, and signaling game theory. It is designed to explain a growing body of experimental results on semantic processing that have accumulated in the absence of a unifying theory since the introduction of electrophysiology and neuroimaging methods. Baggio argues that there is evidence for the existence of three semantic systems in the brain—relational semantics, interpretive semantics, and evolutionary semantics—and he discusses each in turn, developing neural theories of meaning for all three. Moreover, in the course of his argument, Baggio addresses several long-standing issues in the neuroscience of language, including the role of compositionality as a principle of meaning construction in the brain, the role of sensory-motor processes in language comprehension, and the neural and evolutionary links among meaning, consciousness, sociality, and action.

In this 10,000-word essay, written to complement Iain McGilchrist's acclaimed The Master and His Emissary, the author asks why - despite the vast increase in material well-being - people are less happy today than they were half a century ago, and suggests that the division between the two hemispheres of the brain has a critical effect on how we see and understand the world around us. In particular, McGilchrist suggests, the left hemisphere's obsession with reducing everything it sees to the level of minute, mechanistic detail is robbing modern society of the ability to understand and appreciate deeper human values. Accessible to readers who haven't yet read The Master and His Emissary as well as those who have, this is a fascinating, immensely thought-provoking essay that delves to the very heart of what it means to be human.

"There is no issue in science of greater importance than the perplexity concerning the relation between the activity of discrete miscroscopic neurons and the molar psychological processes of which we are all individually aware. Even to consider this issue is to wrestle with one of the greatest intellectual challenges of huyman history. Robert Miller has done just that. ... Furthermore, he has undertaken the task of integration, synthesis, and interpretation with a fervor that can only be admired and a style that is elegant and literate." --Contemporary Psychology

Consciousness is our gateway to experience: it enables us to recognize Van Gogh’s starry skies, be enraptured by Beethoven’s Fifth, and stand in awe of a snowcapped mountain. Yet consciousness is subjective, personal, and famously difficult to examine: philosophers have for centuries declared this mental entity so mysterious as to be impenetrable to science. In The Ravenous Brain, neuroscientist Daniel Bor departs sharply from this historical view, and builds on the latest research to propose a new model for how consciousness works. Bor argues that this brain-based faculty evolved as an accelerated knowledge gathering tool. Consciousness is effectively an idea factory—that choice mental space dedicated to innovation, a key component of which is the discovery of deep structures within the contents of our awareness. This model explains our brains’ ravenous appetite for information—and in particular, its constant search for patterns. Why, for instance, after all our physical needs have been met, do we recreationally solve crossword or Sudoku puzzles? Such behavior may appear biologically wasteful, but, according to Bor, this search for structure can yield immense evolutionary benefits—it led our ancestors to discover fire and farming, pushed modern society to forge ahead in science and technology, and guides each one of us to understand and control the world around us. But the sheer innovative power of human consciousness carries with it the heavy cost of mental fragility. Bor discusses the medical implications of his theory of consciousness, and what it means for the origins and treatment of psychiatric ailments, including attention-deficit disorder, schizophrenia, manic depression, and autism. All mental illnesses, he argues, can be reformulated as disorders of consciousness—a perspective that opens up new avenues of treatment for alleviating mental suffering. A controversial view of consciousness, The Ravenous Brain links cognition to creativity in an ingenious solution to one of science’s biggest mysteries.
