Revealing multiscale architecture of the intact human spine using hierarchical phase contrast tomography

This paper uses HiP-CT to image the human spine at high resolution, revealing multiscale anatomy and microstructural features without exogenous contrast.

In vivo modulation of locus coeruleus activity by light

This study shows light modulates locus coeruleus (LC) activity in an emotion-dependent manner, with higher illuminance dampening responses to negative stimuli and enhancing neutral ones.

The Extremely Brilliant Brain: An Isotropic Microscale Human Brain Dataset

The paper presents a high-resolution isotropic human brain dataset and demonstrates its use for neuroanatomy analysis and visualization.

Regional Hypothalamic Responses to Light Vary Across Developmental Stages but Remain Stable with Time of Day

This study examines how light affects hypothalamic activity in adolescents and young adults across different times of day, finding stable regional responses with developmental differences in magnitude.

Pooling quantitative MRI data: A multi-protocol study of healthy subcortical ageing

This study evaluates how protocol and hardware differences affect pooling quantitative MRI data across sites in healthy aging studies, finding both benefits and drawbacks for analysis outcomes.

Regional activity within the human amygdala varies with season, mood and illuminance

This study investigates how seasonal changes, mood, and light exposure affect regional activity in the human amygdala using fMRI.

Resolving near-micron scale features within a whole sheep head using Hierarchical Phase-Contrast Tomography

This paper demonstrates HiP-CT with EPR for high-resolution imaging of a whole sheep head, enabling near-micron scale visualization of anatomical features without sectioning.

Savings in visuomotor learning is associated with connectivity changes within a cerebello-thalamo-cortical network encoding movement errors

The paper investigates how connectivity changes in a cerebello-thalamo-cortical network during re-adaptation relate to visuomotor learning savings.

The crosstalk between the anterior hypothalamus and the locus coeruleus during wakefulness is associated with low frequency oscillations power during sleep

This study examines the relationship between effective connectivity between the locus coeruleus and hypothalamus subregions and sleep electrophysiology in young and older adults.

Light Impact on Thalamo-Cortical Connectivity During a Cognitive Task Depends on Time of Day and is Different in Teenagers

This study shows that light affects thalamo-cortical connectivity during a cognitive task, with differences based on time of day and age group.

REM sleep quality is associated with balanced tonic activity of the locus coeruleus during wakefulness

The paper investigates the relationship between locus coeruleus (LC) activity during wakefulness and REM sleep quality in humans, finding task-dependent associations.

Regional response to light illuminance across the human hypothalamus

This study investigates how varying light levels affect different regions of the human hypothalamus during cognitive tasks, finding distinct activity patterns linked to task performance.

7 Tesla MRS estimates of GABA concentration relate to physiological measures of tonic inhibition in the human motor cortex

The paper uses 7 Tesla MRS and TMS-hdEEG to show that MRS-GABA correlates with physiological measures of tonic inhibition in the human motor cortex.

Light modulates task-dependent thalamo-cortical connectivity during an auditory attentional task

This study shows blue-enriched light enhances thalamo-cortical connectivity during an auditory attention task, supporting its role in modulating cognitive activity.

In vivo Locus Coeruleus activity while awake is associated with REM sleep quality in healthy older individuals

This study finds that higher locus coeruleus activity during wakefulness in older adults is linked to worse sleep quality and reduced theta band power during REM sleep.

MRI-assessed locus coeruleus contrast and functional response are not associated in young and late middle-aged individuals

The paper investigates the relationship between structural and functional characteristics of the locus coeruleus in young and late middle-aged individuals using MRI and finds no association between LC contrast and functional response.

Interactive mapping of language and memory with the GE2REC protocol

The paper introduces a new protocol called GE2REC to interactively map language and memory networks using MRI in healthy participants, showing robust activation of relevant brain regions.
