Enhancement of sleep slow waves: underlying mechanisms and practical consequences.

Frontiers in Systems Neuroscience, 2014
Even modest sleep restriction, especially the loss of sleep slow wave activity, is invariably associated with slower EEG activity during wake, the occurrence of local sleep in an otherwise awake brain, and impaired performance due to cognitive and memory

Assessment of potential capabilities of Dreem: An ambulatory device for EEG phase-locked acoustic stimulation during sleep

Социально-экологические технологии, 2019
Sleep disorders are one of the significant problems in the modern society. Current research is on the lookout for the nonpharmacological ways to improve sleep quality and slow wave brain activity that plays a crucial role in homeostasis and cognitive ...

Exercise improves the quality of slow-wave sleep by increasing slow-wave stability

Scientific Reports, 2021
Exercise can improve sleep by reducing sleep latency and increasing slow-wave sleep (SWS). Some studies, however, report adverse effects of exercise on sleep architecture, possibly due to a wide variety of experimental conditions used.

L-DOPA increases slow-wave sleep duration and selectively modulates memory persistence in older adults

Frontiers in Behavioral Neuroscience, 2023
IntroductionMillions of people worldwide take medications such as L-DOPA that increase dopamine to treat Parkinson’s disease. Yet, we do not fully understand how L-DOPA affects sleep and memory.

Frontal grey matter microstructure is associated with sleep slow waves characteristics in late midlife [PDF]

, 2022
STUDY OBJECTIVES: The ability to generate slow waves (SW) during non-rapid eye movement (NREM) sleep decreases as early as the 5 th decade of life, predominantly over frontal regions.

From macro to micro: slow-wave sleep and its pivotal health implications

Frontiers in Sleep
Research on slow-wave sleep (SWS) began almost a century ago, not long after the discovery of electroencephalography. From maintaining homeostasis to memory function, the pivotal role of SWS in health has been established.

Human gamma oscillations during slow wave sleep. [PDF]

PLoS ONE, 2012
Neocortical local field potentials have shown that gamma oscillations occur spontaneously during slow-wave sleep (SWS). At the macroscopic EEG level in the human brain, no evidences were reported so far.

Overnight weight loss: relationship with sleep structure and heart rate variability [PDF]

, 2008
Background: Weight loss can be caused by a loss of body mass due to metabolism and by water loss as unsensible water loss, sweating, or excretion in feces and urine.

Closed-Loop Acoustic Stimulation During Sleep in Children With Epilepsy: A Hypothesis-Driven Novel Approach to Interact With Spike-Wave Activity and Pilot Data Assessing Feasibility

Frontiers in Human Neuroscience, 2019
Slow waves, the electroencephalographic (EEG) hallmark of deep sleep, can be systematically manipulated by acoustic stimulation: stimulation time-locked to the down phase of slow waves reduces, whereas stimulation time-locked to the up phase increases ...

Slow wave synchronization and sleep state transitions

Scientific Reports, 2022
Spontaneous synchronization over large networks is ubiquitous in nature, ranging from inanimate to biological systems. In the human brain, neuronal synchronization and de-synchronization occur during sleep, with the greatest degree of neuronal ...
