AP PSYCHOLOGY

Detailed explanation-1: -Dement worked with physiologist Nathaniel Kleitman, PhD, and graduate student Eugene Aserinsky, PhD, to unveil the rich drama of slumber. With this team, Dement discovered and described rapid eye movement sleep-the phase during which we’re most likely to dream-coining the term REM.

Detailed explanation-2: -In September 1953, as a result of work in his laboratory, Kleitman and one of his students, the late Eugene Aserinsky, reported the discovery of rapid eye movements (REMs) during sleep and suggested the association of these eye movements with dreaming.

Detailed explanation-3: -From Chicago, Dement went to New York, where he ran a sleep clinic out of a Manhattan apartment. It was there that he discovered that abnormal REM sleep was a symptom of narcolepsy, a finding that later led to his creation of the multiple sleep latency test (MSLT) as a standard diagnostic tool for narcolepsy.

Detailed explanation-4: -In 1845, a British doctor named John Davy studied the connection between body temperatures and sleep patterns. Then, a French researcher, Henri Pieron, published a book titled The Physiological Problem of Sleep. This marked the first time in history when rest was studied as a health issue.

Detailed explanation-5: -The Professor Emeritus of Psychology, Psychiatry and the College, Rechtschaffen came to the University of Chicago in 1957-joining renowned faculty member Nathaniel Kleitman, who had established the world’s first sleep laboratory and is universally recognized as the father of sleep research.
