Nathaniel Kleitman (April 26, 1895 – August 13, 1999) [1] [2] was an American physiologist and sleep researcher who served as Professor Emeritus in Physiology at the University of Chicago. He is recognized as the father of modern sleep research, and is the author of the seminal 1939 book Sleep and Wakefulness.
Why We Sleep: The New Science of Sleep and Dreams (or simply known as Why We Sleep) is a 2017 popular science book about sleep written by Matthew Walker, an English scientist and the director of the Center for Human Sleep Science at the University of California, Berkeley, who specializes in neuroscience and psychology.
The Committee of Sleep: How Artists, Scientists, and Athletes Use Dreams for Creative Problem-Solving—and How You Can Too is a book by Deirdre Barrett published by Crown/Random House in 2001. Barrett is a psychologist on the faculty of Harvard Medical School.
The circadian rhythm provides a person with a signal for when to sleep and when to wake up. [43] If circadian rhythm and sleep-wake cycle are misaligned, this might lead to negative affect and emotional instability. [44] It has been found that emotions vary depending on the circadian rhythm and the duration of how long one was awake. [45]
Initially, it was thought that sleep was simply a mechanism for the body to "take a break" and reduce wear. Later observations of the low metabolic rates in the brain during sleep seemed to indicate some metabolic functions of sleep. [109] This theory is not fully adequate as sleep only decreases metabolism by about 5–10%.
Physiology professor Nathaniel Kleitman's 1939 book Sleep and Wakefulness, revised 1963, [7] summarized the existing knowledge of sleep, and it was he who proposed the existence of a basic rest-activity cycle. Kleitman, with his students including William C. Dement and Eugene Aserinsky, continued his research throughout the 1900s. O.
The cognitive shuffle is based on Beaudoin’s somnolent information processing theory. [5] [13] The somnolent information processing theory postulates the existence of a sleep onset control system that evolved to ensure that falling asleep tends to happen when it is evolutionarily opportune (safe, timely) to fall asleep. [14]
During standard sleep laboratory measurements, the states of sleep and waking have behavioral, polygraphic, and psychological manifestation within the pontine brainstem. These states are regulated by a reciprocal relationship between two types of neuronal cells, aminergic inhibitory cells such as serotonin and norepinephrine and cholinergic ...
