Sleep-dependent modulation of thalamic brain temperature estimates in humans

This study uses MRS to show that thalamic brain temperature decreases during NREM sleep in humans, with deeper sleep associated with greater temperature drops.

Napping alters Functional Brain Responses in the Aged

This study examines how napping affects functional brain responses in older adults during a working memory task, finding differences in brain activity and performance between nappers and non-nappers.

Napping and circadian sleep-wake regulation during healthy aging.

This study examines the relationship between napping and circadian regulation of sleep in older adults, finding altered melatonin secretion and sleep patterns in nappers.

In vivo marker of brainstem myelin is associated to quantitative sleep parameters in healthy young men

The paper investigates the association between brainstem myelin content and sleep parameters in healthy young men, finding significant links between myelin integrity and sleep quality metrics.

Sleep-dependent structural neuroplasticity after a spatial navigation task: A diffusion imaging study

This study investigates sleep-dependent structural neuroplasticity using diffusion imaging, finding rapid remodelling of neurites and glial cells after spatial navigation learning.

pyActigraphy: open-source python package for actigraphy data visualisation and analysis

pyActigraphy provides an open-source Python package for actigraphy data visualization and analysis, including sleep detection and rest-activity rhythm quantification.

Continued topographical learning- and relearning-dependent activity in the resting state after post-training sleep and wake

The paper investigates offline neural activity changes after learning and relearning using resting state fMRI, finding continued task-related activity and compensatory connectivity after sleep deprivation.

Looking for a reference for large datasets: relative reliability of visual and automatic sleep scoring

The paper compares visual and automatic sleep scoring methods to assess their reliability and variability in large datasets, finding that automatic scoring can be a reliable reference when reproducible.

Preserved wake-dependent cortical excitability dynamics predict cognitive fitness beyond age-related brain alterations

The paper shows that preserved cortical excitability during wakefulness is linked to better cognitive performance in older adults, independent of brain structural changes.
