Increased Stability and Breakdown of Brain Effective Connectivity During Slow-Wave Sleep: Mechanistic Insights from Whole-Brain Computational Modelling

Scientific Reports, 2017
Recent research has found that the human sleep cycle is characterised by changes in spatiotemporal patterns of brain activity. Yet, we are still missing a mechanistic explanation of the local neuronal dynamics underlying these changes.

Neurostimulation techniques to enhance sleep and improve cognition in aging

Neurobiology of Disease, 2020
Sleep plays a critical role in the process of memory consolidation. In particular, during non-rapid eye movement (NREM) slow wave sleep, slow-oscillations, spindles, hippocampal sharp wave ripples, and their phase coupling are involved in the process of ...

Thalamic influence on slow wave slope renormalization during sleep [PDF]

, 2021
OBJECTIVE Slow waves are thought to mediate an overall reduction in synaptic strength during sleep. The specific contribution of the thalamus to this so-called synaptic renormalization is unknown. Thalamic stroke is associated with daytime sleepiness,

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.

Natural Frequencies of Levodopa‐Induced Dyskinesia in Parkinson's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objectives Abnormal involuntary movements, known as dyskinesias, are common complications of levodopa treatment in patients with Parkinson's disease and can significantly impair quality of life. The underlying pathophysiology remains unclear, and current therapeutic options are limited.

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.

Impact of Age on the Diagnostic Yield of Routine EEG in People With Childhood or Juvenile Absence Epilepsy: A Cross‐Sectional Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background We aimed to identify the proportion of individuals with a confirmed diagnosis of childhood absence epilepsy (CAE) or juvenile absence epilepsy (JAE) who show a negative routine EEG (rEEG), and to determine the main factors associated with this finding.
