Amazon.com Review
"I do not believe that you need coherent behavior in science." When an author begins a book with words like these, the reader is allowed to expect a lot. Fortunately, Michel Jouvet delivers with The Paradox of Sleep, a rare synthesis of poetry and hard science covering one of the most bizarre and inexplicable aspects of human experience, the dream. While 20 percent of us don't remember them, it's a safe bet that all of us fly, take tests, or show up at parties in our underwear every night while fast asleep, and neuroscience has only recently caught up with other scientific efforts to explain why. Jouvet was a pioneer who discovered that "paradoxical sleep"--what the rest of us call the REM, or "rapid eye movement" phase--is in fact as different from dreamless sleep as the latter is from waking. This collection of essays, seamlessly woven into a narrative whole, explains the differences between sleep states, discusses relevant animal and human research, explores the meaning of our dreams within the context of our scientific knowledge, and speculates on the evolutionary function of dreaming. Jouvet's prose reaches further than just listing interesting facts and consistently bridges the gap between our 20th-century knowledge and our medieval sense of wonder. How can a modern scientist get away with integrating deep spiritual questions with precise analysis of experimental data? It's a tough question, but one that we can hope more scientists begin asking themselves after reading The Paradox of Sleep. --Rob Lightner

Paradoxical sleep was the phrase coined by Jouvet to describe the dreaming state. The French physiologist, now retired from the University of Lyon, reflects on his life's work with emphasis on the hows and whys of dreaming. In the 1950s, Jouvet, along with a group of researchers in Chicago, related rapid-eye-movement (REM) sleep to dreaming. This state, as different from deep sleep as deep sleep is from wakefulness, occupies up to 100 minutes a night in adults. During dreaming, voluntary limb movements are blocked: The body is essentially paralyzed (except for eye movements and other small movements, such as that of the tongue). Jouvet's early work established that REM sleep and dreaming seem to be the province of warm-blooded animalsbirds and mammals, excluding dolphins. Within those groups, cats may be the star dreamers and sleepers (as most cat owners would attest). When surgery or drugs block the mechanisms that normally paralyze body movements during dreaming, dream actions are actually played out. Cats will stalk, play with imaginary prey, show fear or rage, etc., reflecting the temperament they show while awake. Jouvet is the first to confess to the false starts in dream research he and others have made; he also points to the too easy analogies popularized over the years. The current focus on molecular biology has not been a boon to his field, but neither has the tradition of Freud and psychoanalysis. Jouvet ends with his admittedly speculative theory that we need dreaming to preserve our unique ``psychological heredity.'' He suggests this occurs through iterative programming involving selective activation of various neurons and circuits during dreaming. Jouvet presents a lesson in science: although we are better able to explore the brain with today's sophisticated tools, we will not fathom the purpose of dreams until we go beyond molecules and genes to complexly relate whole organs and systems to functionsa new physiology. --
