Neurochemistry of Consciousness


Book Description

This pioneering book explores in depth the role of neurotransmitters in conscious awareness. The central aim is to identify common neural denominators of conscious awareness, informed by the neurochemistry of natural, drug induced and pathological states of consciousness. Chemicals such as acetylcholine and dopamine, which bridge the synaptic gap between neurones, are the 'neurotransmitters in mind' that form the substance of the volume, which is essential reading for all who believe that unravelling mechanisms of consciousness must include these vital systems of the brain.Up-to-date information is provided on: • Psychological domains of attention, motivation, memory, sleep and dreaming that define normal states of consciousness. • Effects of chemicals that alter or abolish consciousness, including hallucinogens and anaesthetics. • Disorders of the brain such as dementia, schizophrenia and depression considered from the novel perspective of the way these affect consciousness, and how this might relate to disturbances in neurotransmission.

From Chemistry to Consciousness


Book Description

This book reflects on the significant and highly original scientific contributions of Hans Primas. A professor of chemistry at ETH Zurich from 1962 to 1995, Primas continued his research activities until his death in 2014. Over these 50 years and more, he worked on the foundations of nuclear magnetic resonance spectroscopy, contributed to a number of significant issues in theoretical chemistry, helped to clarify central topics in quantum theory and the philosophy of physics, suggested innovative ways of addressing interlevel relations in the philosophy of science, and introduced cutting-edge approaches in the flourishing young field of scientific studies of consciousness. His work in these areas of research and its continuing impact is described by noted experts, colleagues, and collaborators of Primas. All authors contextualize their contributions to facilitate the mutual dialog between these fields.




Molecular Consciousness


Book Description

Mind and matter are connected through information at the atomic level • Explains how your state of mind is profoundly related to the flow of chemical information during the interactions of your molecules • Reveals how each atom of the universe is intrinsically linked with all other atoms through their memories and the information they carry • Explores the concrete manifestations of this “molecular consciousness,” such as intuition and the appearance of life on Earth The molecules of living organisms are in constant communication, storing and transmitting information both at the intracellular level as well as across vast distances. The mystery of how this communication occurs--whether through molecular structure, chemical reactions, entangled states, or some other method--has baffled biologists, chemists, and quantum physicists for more than a century. Revealing the intimate connections between mind and matter, Françoise Tibika explains that conscious communication exists all the way down to the very molecules of which we--and the universe--are made. Using the fundamental laws of thermodynamics to support her argument--especially the first law: “energy is neither created nor destroyed”--as well as modern scientific research in quantum physics and molecular biology, Tibika explores how each imperishable atom of the universe is intrinsically linked with all other atoms through their memories and the information they carry. She shows not only how each atom of your being is part of the greater whole of the universe but also how your thoughts, feelings, and state of mind are profoundly related to the activity of each of your molecules. Just as we are undergoing constant transformation by the molecules surrounding us, our own molecules are continuously transforming the network of which we are a part. Exploring the concrete manifestations of this molecular consciousness, such as intuition, Tibika reveals how, through effecting conscious change at the molecular level, our actions have far-reaching significance in a universe that is not blind to our presence.




The Chemistry of Mind-altering Drugs


Book Description

This fascinating book presents a scientifically objective, and thoroughly documented exposition of the pharmacological and psychological effects of nearly every known substance that affects human consciousness, from alcohol to Zopiclone. It also features first-hand accounts and descriptions of the social, cultural, and religious milieus in which many psychotropic plants are used, and discusses historical allusions to many literary and scientific figures who used or wrote of mind-altering drugs, including Freud, Dickens, Yeats, and Huxley. Intended for a wide audience of general readers seeking unbiased information, the book gives an accessible explanation of drug-receptor interaction and organic chemical structures, as well as descriptions of the discovery, isolation, and syntheses of the chemical substances responsible for drug activity. Written by an experienced chemist, the book nevertheless keeps technical information to a minimum.




The River of Consciousness


Book Description

From the bestselling author of The Man Who Mistook His Wife for a Hat, a collection of essays that displays Oliver Sacks's passionate engagement with the most compelling ideas of human endeavor: evolution, creativity, memory, time, consciousness, and experience. "Curious, avid and thrillingly fluent." —The New York Times Book Review In the pieces that comprise The River of Consciousness, Dr. Sacks takes on evolution, botany, chemistry, medicine, neuroscience, and the arts, and calls upon his great scientific and creative heroes--above all, Darwin, Freud, and William James. For Sacks, these thinkers were constant companions from an early age. The questions they explored--the meaning of evolution, the roots of creativity, and the nature of consciousness--lie at the heart of science and of this book. The River of Consciousness demonstrates Sacks's unparalleled ability to make unexpected connections, his sheer joy in knowledge, and his unceasing, timeless endeavor to understand what makes us human.




Stairway to the Mind


Book Description

Human consciousness has perplexed philosophers, artists and scientists for centuries. Some hold it to be purely physical, while others believe it transcends the material world. Now comes a book that offers a new perspective - based entirely on evidence from the natural sciences - whereby materialism and dualism co-exist. The author - a distinguished pioneer of nonlinear dynamics - bases his argument on a hierarchical view of mental organization; a stairway. Atoms give rise to molecules, neurons form the brain and individual consciousness leads to shared culture. All steps are needed to complete the picture and each level derives from the previous one. The book shows specialists how each of their fields adds to the overall picture, while providing general readers with an introduction to this investigation.




The Emerging Physics of Consciousness


Book Description

Seeks answers to these questions using the underlying assumption that consciousness can be understood using the intellectual potential of modern physics and other sciences. There are a number of theories of consciousness, some based on classical physics while others require the use of quantum concepts. The latter ones have drawn criticism from the parts of the scientific establishment while simultaneously claiming that classical approaches are doomed to failure. The contributing authors presents a spectrum of opinions from both sides of this on-going scientific debate, allowing readers to decide for themselves which of the approaches are most likely to succeed.




The Feeling of Life Itself


Book Description

A thought-provoking argument that consciousness—more widespread than previously assumed—is the feeling of being alive, not a type of computation or a clever hack In The Feeling of Life Itself, Christof Koch offers a straightforward definition of consciousness as any subjective experience, from the most mundane to the most exalted—the feeling of being alive. Psychologists study which cognitive operations underpin a given conscious perception. Neuroscientists track the neural correlates of consciousness in the brain, the organ of the mind. But why the brain and not, say, the liver? How can the brain—three pounds of highly excitable matter, a piece of furniture in the universe, subject to the same laws of physics as any other piece—give rise to subjective experience? Koch argues that what is needed to answer these questions is a quantitative theory that starts with experience and proceeds to the brain. In The Feeling of Life Itself, Koch outlines such a theory, based on integrated information. Koch describes how the theory explains many facts about the neurology of consciousness and how it has been used to build a clinically useful consciousness meter. The theory predicts that many, and perhaps all, animals experience the sights and sounds of life; consciousness is much more widespread than conventionally assumed. Contrary to received wisdom, however, Koch argues that programmable computers will not have consciousness. Even a perfect software model of the brain is not conscious. Its simulation is fake consciousness. Consciousness is not a special type of computation—it is not a clever hack. Consciousness is about being.




Biophysics Of Consciousness: A Foundational Approach


Book Description

The problem of how the brain produces consciousness, subjectivity and 'something it is like to be' remains one of the greatest challenges to a complete science of the natural world. While various scientists and philosophers approach the problem from their own unique perspectives and in the terms of their own respective fields, Biophysics of Consciousness: A Foundational Approach attempts a consilience across disparate disciplines to explain how it is possible that an objective brain produces subjective experience.This volume unites the crème de la crème of physicists, neuroscientists, and psychiatrists in the attempt to understand consciousness through a foundational approach encompassing ontological, evolutionary, neurobiological, and Freudian interpretations with the focus on conscious phenomena occurring in the brain. By integrating the perspectives of these diverse disciplines with the latest research and theories on the biophysics of the brain, the book tries to explain how consciousness can be an adaptive and causal element in the natural world.




Consciousness


Book Description

J. Allan Hobson presents a critical overview of conceptions of consciousness, relating it to specific areas of the brain and their chemical and physical states. He charts the various states of waking, dreaming and non-consciousness using the theories and data of neuroscience, psychiatry and neurophysiology, whilst conveying the mysterious and seductive nature of his subject.
