Synaptic mechanisms that contribute to human memory consolidation remain largely unexplored. Consolidation critically relies on sleep. During slow wave sleep, neurons exhibit characteristic membrane potential oscillations known as UP and DOWN states. Coupling of memory reactivation to these slow oscillations promotes consolidation, though the underlying mechanisms remain elusive. Here, we performed axonal and multineuron patch-clamp… Continue reading Membrane potential states gate #synaptic consolidation in human neocortical tissue

Short #Sleep Duration and #Hypertension: A Double Hit for the #Brain
Short sleep duration has been associated with an increased risk of cognitive impairment and dementia. Short sleep is associated with elevated blood pressure, yet the combined insult of short sleep and hypertension on brain health remains unclear. We assessed whether the association of sleep duration with cognition and vascular brain injury was moderated by hypertensive… Continue reading Short #Sleep Duration and #Hypertension: A Double Hit for the #Brain
Associations of accelerometer-measured #physical activity, #sedentary behaviour, and #sleep with next-day #cognitive performance in older adults: a micro-longitudinal study
BackgroundPrevious studies suggest short-term cognitive benefits of physical activity occurring minutes to hours after exercise. Whether these benefits persist the following day and the role of sleep is unclear. We examined associations of accelerometer-assessed physical activity, sedentary behaviour, and sleep with next-day cognitive performance in older adults.MethodsBritish adults aged 50-83 years (N = 76) without evidence of… Continue reading Associations of accelerometer-measured #physical activity, #sedentary behaviour, and #sleep with next-day #cognitive performance in older adults: a micro-longitudinal study
Association of Self-Reported #Sleep Characteristics With Neuroimaging Markers of Brain #Aging Years Later in Middle-Aged Adults
ObjectivesTo determine the association between early midlife sleep and advanced brain aging patterns in late midlife.MethodsUsing the CARDIA study, we analyzed sleep data at baseline and 5 years later, focusing on short sleep duration, bad sleep quality (SQ), difficulty initiating and maintaining sleep (DIS and DMS), early morning awakening (EMA), and daytime sleepiness. These were… Continue reading Association of Self-Reported #Sleep Characteristics With Neuroimaging Markers of Brain #Aging Years Later in Middle-Aged Adults
A #hippocampal circuit mechanism to balance #memory reactivation during #sleep
Editor’s summaryDuring sleep, there is an increase in the coordinated firing of neuronal ensembles that were previously active during behavior. These hippocampal sharp-wave ripples are necessary for sleep-dependent memory consolidation. However, how the hippocampus regulates such increases in ensemble reactivation and synchrony while keeping the overall homeostatic balance of the network is not known. Karaba et… Continue reading A #hippocampal circuit mechanism to balance #memory reactivation during #sleep
#Sleep duration, chronotype, #health and lifestyle factors affect cognition: a UK Biobank cross-sectional study
Objective To explore the nuanced relationship between sleep patterns, chronotype, quality and the influence of health and lifestyle factors on cognitive performance.Design, setting, participants This cross-sectional analysis used ordinary least squares regression within the UK Biobank database, assessing 26 820 participants aged 53–86 years, categorised into two cohorts: Cohort 1 (10 067 participants, 56% female; completed all four… Continue reading #Sleep duration, chronotype, #health and lifestyle factors affect cognition: a UK Biobank cross-sectional study
#Acupuncture and #Sleep Quality Among Patients With #Parkinson DiseaseA Randomized Clinical Trial
Importance Poor sleep quality greatly impairs quality of life and accelerates deterioration in patients with Parkinson disease (PD), but current remedies remain limited. Acupuncture, used as an adjunctive therapy with anti-Parkinson medications, has shown positive effects in patients with PD. However, high-quality clinical evidence to support the effectiveness of acupuncture for patients with PD and poor… Continue reading #Acupuncture and #Sleep Quality Among Patients With #Parkinson DiseaseA Randomized Clinical Trial
Consumption of #fruits and #vegetables and its association with #sleep duration among Finnish adult population: a nationwide cross-sectional study
Introduction: Sleep and diet are crucial determinants of overall health and wellbeing, with the potential to mutually influence each other. This study examined the association between sleep duration and fruits and vegetables (FV) consumption among Finnish adults.Methods: The study analyzed data from the National FinHealth 2017 Study involving 5,043 adults aged 18 years and above. Participants reported… Continue reading Consumption of #fruits and #vegetables and its association with #sleep duration among Finnish adult population: a nationwide cross-sectional study
Association Between Electronic Diary–Rated #Sleep, Mood, Energy, and #Stress With Incident #Headache in a Community-Based Sample
The aim of this study was to examine the diurnal links between average and changes in average levels of prospectively rated mood, sleep, energy, and stress as predictors of incident headache in a community-based sample.MethodsThis observational study included structured clinical diagnostic assessment of both headache syndromes and mental disorders and electronic diaries that were administered… Continue reading Association Between Electronic Diary–Rated #Sleep, Mood, Energy, and #Stress With Incident #Headache in a Community-Based Sample
