Are infraslow oscillations the missing link between sleep and Alzheimer's?

The paper investigates infraslow oscillations (ISO) in sleep and their potential link to Alzheimer's disease by analyzing EEG data and correlating ISO metrics with biomarkers.

Mutation-related apparent myelin, not axon density, drives white matter differences in premanifest Huntington's disease: Evidence from in vivo ultra-strong gradient MRI

This study uses ultra-strong gradient MRI to show that myelin changes, not axon density, are linked to premanifest Huntington's disease, with mutation size correlating with myelin levels.

The bidirectional causal effects of brain morphology across the life course and risk of Alzheimers disease: A cross-cohort comparison and Mendelian randomization meta-analysis

This study uses Mendelian randomization to examine bidirectional causal effects between brain morphology and Alzheimer's disease risk across different life stages.

Multi-compartment analysis of the complex gradient-echo signal quantifies myelin breakdown in premanifest Huntington's disease

This study uses multi-compartment MRI signal analysis to quantify myelin breakdown in premanifest Huntington's disease, finding reduced myelin water fraction and age-related executive function decline.

EEG microstate complexity for aiding early diagnosis of Alzheimer's disease

This study uses EEG microstate complexity and spectral measures to improve early diagnosis of Alzheimer's disease with high sensitivity and specificity.

Drumming motor sequence training induces myelin remodelling in Huntington's disease: a longitudinal diffusion MRI and quantitative magnetization transfer study

This study examines if drumming training induces myelin remodelling in Huntington's disease patients using diffusion MRI and qMT imaging, finding increased MPF in specific white matter regions post-training.

Dopamine-gated memory selection during slow wave sleep

This study investigates how dopamine affects memory consolidation during sleep, finding that it enhances forgetting of weak memories and increases slow wave sleep duration.

Measuring the relationship between sleep, physical activity and cognition

This study investigates the effects of a physical activity intervention on sleep and cognition in healthy adults, finding mixed results with no sustained impact on sleep but improved cognitive performance.

Effects of Parkinson’s disease and dopamine on digit span measures of working memory

This study investigates how Parkinson’s disease and dopamine affect working memory by testing digit span tasks in patients and healthy controls with and without medication.

Levodopa’s effects on expression of reinforcement learning

This study investigates levodopa's effect on choice performance in reinforcement learning, finding no impact on accuracy or expression of reinforced values.
