Dissociable contributions of cortical thickness and surface area to cognitive ageing: evidence from multiple longitudinal cohorts.

This study examines how cortical thickness and surface area contribute to cognitive ageing using longitudinal data from multiple cohorts, finding thickness declines more steeply and is more strongly linked to cognitive change.

Optimising 7T-fMRI for imaging regions of magnetic susceptibility

This study improves 7T-fMRI quality in susceptibility-prone regions using multi-echo and multiband sequences, enhancing BOLD signal and GLM precision.

Test-retest reliability of resting-state fMRI functional connectivity: impact of scan length and number of participants

This study evaluates the test-retest reliability of resting-state fMRI connectivity metrics based on scan length and participant number, finding that scan length has a stronger impact than participant count.

Complementary MR measures of white matter and their relation to cardiovascular health and cognition

The paper identifies latent factors underlying white matter metrics using MRI data from a cohort of healthy adults and links these factors to cardiovascular health and cognitive performance.

Comparing the effect of multi gradient echo and multi band fMRI during a semantic task

This study compares multi gradient echo and multi band fMRI protocols during a semantic task, finding multi-band improves activation detection and decoding, while multi-echo enhances sensitivity in susceptibility-prone regions.

Correcting for Superficial Bias in 7T Gradient Echo fMRI

This study compares methods to correct superficial bias in 7T Gradient-Echo fMRI data and finds that ratio of ROI means and Deming regression are most effective.

Diffusional Kurtosis Imaging in the Diffusion Imaging in Python Project

This paper implements Diffusional Kurtosis Imaging (DKI) in the DIPY project, demonstrating its utility for microstructural analysis and tractography in brain imaging.

Now you see it, now you don't: optimal parameters for interslice stimulation in concurrent TMS-fMRI

This paper identifies optimal timing parameters for delivering TMS during fMRI slice gaps to minimize artifacts, achieving up to ~10 Hz stimulation frequency.

Sensory attenuation is related to dopamine dose in Parkinson’s disease

This study investigates how dopamine levels in Parkinson’s disease patients affect sensory attenuation during voluntary movements, finding a negative correlation with motor severity and a positive correlation with dopamine dose.

Strong and specific associations between cardiovascular risk factors and brain white matter micro- and macro-structure in health ageing

This study examines the associations between cardiovascular risk factors and white matter structure in aging, finding that systolic blood pressure, diastolic blood pressure, and heart rate independently impact white matter health.

Physical activity predicts population-level age-related differences in frontal white matter

The paper shows that physical activity preserves frontal white matter integrity and reduces age-related slowing in a population-based sample.

Prospective Motion correction improves the sensitivity of fMRI pattern decoding

This study shows that prospective motion correction improves multi-voxel pattern decoding in fMRI at higher resolutions.

Optimization of a free water elimination two-compartment model for diffusion tensor imaging.

This paper provides an open-source implementation of a two-compartment free water elimination model for diffusion tensor imaging and evaluates its performance using simulations.
