How the brain consolidates memory during deep sleep

Research strongly suggests that sleep, which constitutes about a third of our lives, is crucial for learning and forming long-term memories. But exactly how such memory is formed is not well understood and remains, despite considerable research, a central question … Continue reading

Sleep Is Irreplaceable for the Recovery of the Brain

Resting is no substitute for deep sleep when it comes to keeping up with the intensive performance demands of daily life. Sleep is ubiquitous in animals and humans and vital for healthy functioning. Thus, sleep after training improves performance on … Continue reading

The sleep-deprived human brain

How does a lack of sleep affect our brains? In contrast to the benefits of sleep, frameworks exploring the impact of sleep loss are relatively lacking. Importantly, the effects of sleep deprivation (SD) do not simply reflect the absence of … Continue reading

Cueing newly learned information in sleep improves memory

Scientists have long known that sleep plays an important role in the formation and retention of new memories. That process of memory consolidation is associated with sudden bursts of oscillatory brain activity, called sleep spindles, which can be visualized and … Continue reading

Sleep loss causes social withdrawal and loneliness

Loneliness and social isolation markedly increase mortality risk and are linked to numerous mental and physical comorbidities, including sleep disruption. But does sleep loss causally trigger loneliness? Here, we demonstrate that a lack of sleep leads to a neural and behavioral phenotype of … Continue reading

How the brain learns during sleep

Researchers from Ruhr-Universität Bochum and the University of Bonn have investigated which activity patterns occur in the brain when people remember or forget things. They were interested in how the brain replays and stores during sleep what it had learned … Continue reading

Aging and the Change in Fatigue and Sleep

Fatigue is prevalent in the population and usually linked to sleep problems, and both are related to age. However, previous studies have been cross-sectional. The purpose of the present study was to investigate the trajectories of sleep and fatigue across … Continue reading

Sleep Better, Parent Better

Study reveals mothers who have insufficient sleep, or lack of quality sleep, are more irritable, suffer impaired attention and are less consistent in their parenting of their adolescents. Research has shown that consistently not getting enough sleep, or getting poor … Continue reading

Untreated Sleep Apnea in Children Can Harm Brain Cells Tied to Cognition and Mood

Study reports reduced gray matter in areas of the brain associated with mood and cognition in children with obstructive sleep apnea. MRI scans link chronically disrupted sleep to widespread brain cell damage. A study comparing children between 7 and 11 years … Continue reading

Sleep after learning strengthens connections between brain cells and enhances memory

Researchers show for the first time that sleep after learning encourages the growth of dendritic spines, the tiny protrusions from brain cells that connect to other brain cells and facilitate the passage of information across synapses, the junctions at which … Continue reading
