Thalamic Nuclei Functional Controllability Accounts for Cognitive Impairment in Multiple Sclerosis Over and Above Structural Damage

The paper investigates how thalamic functional controllability contributes to cognitive impairment in MS beyond structural damage, finding it independently predicts cognitive performance.

Thalamic Network Controllability Predicts Cognitive Impairment in Multiple Sclerosis

This study shows that reduced thalamic network controllability in MS patients predicts cognitive impairment better than thalamic volume.

Using dual-calibrated functional MRI to map brain oxygen supply and consumption in multiple sclerosis

This study uses dual-calibrated fMRI to show reduced oxygen supply and consumption in MS patients without changes in oxygen extraction, suggesting impaired oxygen utilization or transfer.

Cerebral Metabolic Changes during Visuomotor Adaptation Assessed using Quantitative FMRI

This study uses calibrated fMRI to examine metabolic and blood flow changes during visuomotor adaptation in healthy humans, finding that CMRO2 decreases faster than BOLD or CBF but the flow-metabolism coupling ratio remains stable.

A frequency-domain machine learning method for dual-calibrated fMRI mapping of oxygen extraction fraction (OEF) and cerebral metabolic rate of oxygen consumption (CMRO2)

This paper introduces a machine learning method for dual-calibrated fMRI to estimate OEF and CMRO2, showing reduced computation time, error, and bias compared to existing methods.

Tractography in the presence of white matter lesions in multiple sclerosis

This study compares tractography algorithms in MS patients to assess their ability to segment white matter tracts despite lesions, showing that individual tract segmentation is feasible and reliable.

Assessment of the effects of aerobic fitness on cerebrovascular function in young adults using multiple inversion time arterial spin labelling MRI

This study examines the relationship between aerobic fitness and cerebrovascular function in young adults, finding lower cerebral blood flow and higher cerebrovascular reactivity with higher fitness levels.
