Henri later wrote the first book in 1913, “Le probleme physiologique du sommeil” on causes of sleep viewed in a physiological perspective. This book has been considered as the breakthrough to modern approach of sleep (popular science, 1933).
He also authored other books, “Thought and the Brain” and “Vocabulaire de la psychologe” that was published in 1987 and reprinted in 1999 and 1990 respectively.
Nathaniel Kleitman (1895-1999)
Nathaniel Kleitman was a professor emeritus at the
In 1953, he, with one of his students, Eugene Aserinsky, discovered the rapid eye movement (REM) during sleep and related it to brain activity while sleeping. In the 1950s he and his colleagues revealed that sleep was an activity that is both dynamic and diverse process. This finding led to the discovery that the brain is activate during sleep. His findings were important as this new information was used to discover ways to treat sleep disorders. He explained sleep in its relation to wakefulness (Stireade, 2010). He continued with further research on eye movement and later he and another of his students William Dement recorded their findings on sleep and dreaming and the brain activity of EEG (Electroencephalograh). He also discovered that sleep deprivation affects the minds alertness. This student became a renowned researcher who started a sleep laboratory at
Nathaniel’s research on sleep was conducted using himself, his family and friends as the research subjects. It is said that he once spent 180 years without sleep as he tried to discover the effects of sleep deprivation. He also recorded the sleep patterns of his daughter right from birth into their adulthood.
