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.

The problem of exactly how these images are stored and manipulated within the human brain, in particular within language and communication, remains a fertile area of study. One of the longest-running research topics on the mental image has basis on the fact that people report large individual differences in the vividness of their images.
Falling asleep can be pretty tricky when your mind and body are out of sync, and the 30,000-foot view of the subject reveals that disharmony between the two typically stems from factors like ...
The electrical activity seen on an EEG represents brain waves. The amplitude of EEG waves at a particular frequency corresponds to various points in the sleep-wake cycle, such as being asleep, being awake, or falling asleep. [18] Alpha, beta, theta, gamma, and delta waves are all seen in the different stages of sleep.
Young woman asleep over study materials. The relationship between sleep and memory has been studied since at least the early 19th century.Memory, the cognitive process of storing and retrieving past experiences, learning and recognition, [1] is a product of brain plasticity, the structural changes within synapses that create associations between stimuli.
Subjects undergo a series of five 20-minute sleeping opportunities with an absence of alerting factors at 2-hour intervals on one day. The test is based on the idea that the sleepier people are, the faster they will fall asleep. [15] [16] The Maintenance of Wakefulness Test (MWT) is also used to quantitatively assess daytime sleepiness. This ...
A 2001 study by Harvard psychologist Deirdre Barrett found that, while problems can also be solved in full-blown dreams from later stages of sleep, hypnagogia was especially likely to solve problems which benefit from hallucinatory images being critically examined while still before the eyes. [24]
