Can Immersive Sound Therapy Counteract Neurodegeneration by Enhancing Glymphatic Clearance? Comment on Sachdeva et al. Effects of Sound Interventions on the Permeability of the Blood–Brain Barrier and Meningeal Lymphatic Clearance. Brain Sci. 2022, 12, 742

Brain Sciences, 2023
We would like to congratulate Sachdeva and colleagues for establishing an informative review regarding the effects of music/sound exposure on blood–brain barrier permeability and meningeal lymphatic/glymphatic clearance, and would appreciate the ...

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 ...

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 ...

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 ...

Effects of Cortical Cooling on Activity Across Layers of the Rat Barrel Cortex

Frontiers in Systems Neuroscience, 2020
Moderate cortical cooling is known to suppress slow oscillations and to evoke persistent cortical activity. However, the cooling-induced changes in electrical activity across cortical layers remain largely unknown.

Decoupling of sleep-dependent cortical and hippocampal interactions in a neurodevelopmental model of schizophrenia [PDF]

, 2012
Rhythmic neural network activity patterns are defining features of sleep, but interdependencies between limbic and cortical oscillations at different frequencies and their functional roles have not been fully resolved.

Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

FEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Deep sleep slow wave–spindle coupling is selectively linked to plasma amyloid-β levels in older adults in clinical trials

Scientific Reports
Slow wave activity, the signature of deep/slow wave sleep, has consistently been linked to amyloid-beta (Aβ), a biomarker of neurodegeneration. Less is known about how Aβ relates to specific microstructural processes within slow wave sleep, such as the ...
