Sleep deprivation may additionally affect memory by reducing the proliferation of cells in the hippocampus. [51] Sleep deprivation has also been associated with decreased overall membrane excitability of neurons in the brain. Activation of these membranes is critical for the formation of memories. [52]
Sleep deprivation is common as it affects about one-third of the population. [3] The National Sleep Foundation recommends that adults aim for 7–9 hours of sleep per night, while children and teenagers require even more. For healthy individuals with normal sleep, the appropriate sleep duration for school-aged children is between 9 and 11 hours.
A new study in mice suggests the hypothesis that brain-cleansing occurs during sleep may be inaccurate. ... (non-sleep deprived) sleep, and across a full normal 24-hour sleep-wake cycle,” he ...
Sleep deprivation was also found to increase beliefs of being correct, especially if they were wrong. Another study reported that the performance on free recall of a list of nouns is significantly worse when sleep deprived (an average of 2.8 ± 2 words) compared to having a normal night of sleep (4.7 ± 4 words).
The study found that several sleep characteristics, including sleep quality, early morning awakening, and difficulty falling asleep or staying asleep, were linked to accelerated brain aging ...
People with high blood pressure who slept for shorter durations were more likely to show poor cognitive function and increased levels of markers of brain aging and injury, a new study has found.
An fMRI recorded brain activity during a verbal learning task of participants either having a normal night of sleep or those deprived of 34.7 (± 1.2) hours of sleep. The task alternated between a baseline condition of determining whether nouns were upper or lower case, and an experimental condition of memorizing a list of nouns.
In a mouse study, researchers found that zolpidem (Ambien), a common sleep aid, could prevent the brain from effectively clearing up 'waste', though it remains unclear whether this could affect ...
