Allan Hobson sets out a compelling—and controversial—theory of consciousness. Our brain-mind, as he calls it, is not a fixed identity but a dynamic balancing act between the chemical systems that regulate waking and dreaming. Drawing on his work both as a sleep researcher and as a psychiatrist, Hobson looks in particular at the strikingly similar chemical characteristics of the states of dreaming and psychosis. His underlying theme is that the form of our thoughts, emotions, dreams, and memories derive from specific nerve cells and electrochemical impulses described by neuroscientists. Among the questions Hobson explores are: What are dreams? Do they have any hidden meaning, or are they simply emotionally salient images whose peculiar narrative structure refects the unique neurophysiology of sleep? And what is the relationship between the delirium of our dream life and psychosis? Originally published by Little, Brown under the title The Chemistry of Conscious States.

In this fascinating book, Harvard researcher Hobson offers an intriguing look at the nightly odyssey through the illusory world of dreams. Hobson describes how the theory of dreaming has advanced dramatically over the past 50 years, sparked by the use of EEGs in the 1950s and by recent innovations in brain imaging. 20 illustrations.

Focusing on dreaming to explain the mechanisms of sleep and sleep laboratory science, this book explores how the new science of dreaming is affecting theories in psychoanalysis, and how it is helping our understanding of the causes of mental illness.

What is dreaming, and what causes it? Why are dreams so strange and why are they so hard to remember? Replacing dream mystique with modern dream science, J. Allan Hobson provides a new and increasingly complete picture of how dreaming is created by the brain. Focusing on dreaming to explain the mechanisms of sleep, this book explores how the new science of dreaming is affecting theories in psychoanalysis, and how it is helping our understanding of the causes of mental illness. J. Allan Hobson investigates his own dreams to illustrate and explain some of the fascinating discoveries of modern sleep science, while challenging some of the traditionally accepted theories about the meaning of dreams. He reveals how dreaming maintains and develops the mind, why we go crazy in our dreams in order to avoid doing so when we are awake, and why sleep is not just good for health but essential for life.

These pocket-sized books are the perfect way to get ahead in a new subject quickly. Our expert authors combine facts, analysis, perspective, new ideas, and enthusiasm to make interesting and challenging topics highly readable.

A pioneer in sleep and dream science surveys his life and work through the lens of dreaming and consciousness. J. Allan Hobson's scientific experimentation began in childhood, with a soot-filled investigation into the capacity of a chimney to admit Santa Claus. (He discovered that even with the damper open the chimney was far too narrow.) Hobson's life as an experimentalist has continued through a pioneering career devoted to aligning psychology and biology and to investigating the relationship of dreaming and consciousness. In Dream Life, Hobson conducts an experimental investigation into his life and work. Hobson charts his developing consciousness through a vividly imagined conception (in October of 1932), birth, and babyhood, offering a theory about "protoconsciousness" in fetuses and infants. He recounts his youthful zeal for scientific discovery, his early sexual experimentation, and his education. He describes taking on the entrenched Freudians at Harvard Medical School in the 1950s, as a maverick psychiatrist who wanted to replace psychoanalysis with biological science. He describes his further studies, his marriages and love affairs, his travels, and what he learned about the brain from his whiplash-induced amnesia after a 1963 automobile accident and from his "brain death" after a stroke in 2001. Through it all, Hobson uses his life as the ultimate case study for his theory that REM sleep provides a test pattern that allows the brain to develop "offline." Dreams—most intense in REM sleep, when the brain is active—need no Freudian-style decoding, he says. Dreaming is a glorious mental state, to be enjoyed and studied for what it tells us about consciousness.

An investigation into the brain's chemistry and the mechanisms of chemically altered states of consciousness. In this book, J. Allan Hobson offers a new understanding of altered states of consciousness based on knowledge of how our brain chemistry is balanced when we are awake and how that balance shifts when we fall asleep and dream. He draws on recent research that enables us to explain how psychedelic drugs work to disturb that balance and how similar imbalances may cause depression and schizophrenia. He also draws on work that expands our understanding of how certain drugs can correct imbalances and restore the brain's natural equilibrium. Hobson explains the chemical balance concept in terms of what we know about the regulation of normal states of consciousness over the course of the day by brain chemicals called neuromodulators. He presents striking confirmation of the principle that every drug that has transformative effects on consciousness interacts with the brain's own consciousness-altering chemicals. In the section called "The Medical Drugstore," Hobson describes drugs used to counteract anxiety and insomnia, to raise and lower mood, and to eliminate or diminish the hallucinations and delusions of schizophrenia. He discusses the risks involved in their administration, including the possibility of new disorders caused by indiscriminate long-term use. In "The Recreational Drugstore," Hobson discusses psychedelic drugs, narcotic analgesia, and natural drugs. He also considers the distinctions between legitimate and illegitimate drug use. In the concluding "Psychological Drugstore," he discusses the mind as an agent, not just the mediator, of change, and corrects many erroneous assumptions and practices that hinder the progress of psychoanalysis.
