Challenging sleep homeostasis

Neurobiology of Sleep and Circadian Rhythms, 2021
In this commentary, I play the Devil’s advocate and assume the title of High Contrarian. I intend to be provocative to challenge long-standing ideas about sleep. I blame all on Professor Craig Heller, who taught me to think this way as a graduate student

Herbal extracts modulate the amplitude and frequency of slow waves in circular smooth muscle of mouse small intestine [PDF]

, 2004
Background: Herbal preparations like STW 5 (Iberogast(R)) are widely used drugs in the treatment of dyspepsia and motility-related disorders of the gastrointestinal tract.

Arousal-Mediated Sleep Disturbance Persists During Cocaine Abstinence in Male Mice

Frontiers in Neuroscience, 2022
Acute cocaine disturbs sleep on a dose-dependent basis; however, the consequences of chronic cocaine remain unclear. While the arousal promotion following cocaine has been well-established, effects of cocaine on sleep after termination of chronic cocaine

Propagated infra-slow intrinsic brain activity reorganizes across wake and slow wave sleep

eLife, 2015
Propagation of slow intrinsic brain activity has been widely observed in electrophysiogical studies of slow wave sleep (SWS). However, in human resting state fMRI (rs-fMRI), intrinsic activity has been understood predominantly in terms of zero-lag ...

Relationship Between Sleep and Memory Consolidation

Türk Uyku Tıbbı Dergisi, 2023
Sleep and memory are complex phenomena that are not fully understood, and the underlying mechanisms are still not fully understood. Besides being an adaptive behavior, sleep can modulate plasticity in the brain at the level of synaptic connections ...

Slow-Wave Transmission Line Transformers/Baluns [PDF]

, 2012
The design and analysis of a miniaturized transmission line transformer/balun for RF applications is proposed. A novel right-handed slow-wave line using three-dimensional periodic substrate metallization is proposed, where each unit cell is made up of a ...

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.

Slow Wave Sleep Is a Promising Intervention Target for Alzheimer’s Disease

Frontiers in Neuroscience, 2020
Alzheimer’s disease (AD) is the major cause of dementia, characterized by the presence of amyloid-beta plaques and neurofibrillary tau tangles. Plaques and tangles are associated with sleep-wake cycle disruptions, including the disruptions in non-rapid ...

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 ...
