The paper maps human hippocampal perfusion and microvascular pulsatility across age using MRI and integrates these with histological and transcriptomic data, revealing distinct spatial organization and age-related differences.

The paper introduces CCSI, a metric linking cortical blood flow and cellular architecture, showing its correlation with metabolic and structural features across brain regions.

This study analyzes fMRI-complexity trajectories across the lifespan using multiscale sample entropy and finds a nonlinear peak in brain complexity around age 23, with gender differences and associations with executive function.

This study compares fMRI complexity and tau-PET in classifying cognitive impairment, finding fMRI matches tau-PET performance with better F1-score and AUC.

This paper introduces a permanent acoustic window for high-resolution, non-invasive ultrasound imaging of human brain activity, demonstrating its use in mapping cortical responses to finger movement.

The paper investigates age and sex differences in BBB function using MRI in 186 participants, finding more pronounced decline in males starting in the early 60s, particularly in parietal and temporal regions.

This paper introduces a pipeline for mapping cerebral small vessel density using 3D black-blood MRI, finding higher density in young subjects and correlations with cognitive scores in aged subjects.

The paper correlates rs-fMRI complexity, measured by entropy, with tau-PET in Alzheimer's disease, showing associations with cognitive decline mediated through tau accumulation.

This study identifies reduced functional connectivity between reward and inhibitory control networks in pre-adolescent children with binge eating disorder compared to controls.

This paper introduces a 3D zoomed arterial spin labeling technique at 7T to quantitatively measure laminar cerebral blood flow in human brain regions during rest and task activation.

This study compares the effects of high-definition tDCS over the motor hotspot and premotor cortex on motor network excitability, finding greater responsiveness and fMRI complexity changes with premotor stimulation.

This study compares neurofeedback performance in head-mounted virtual reality (HMD-VR) and computer screen environments, finding higher embodiment in HMD-VR correlates with better performance.
