Hemispheric lateralization of white matter microstructure in children and its potential role in sensory processing dysfunction

Frontiers in Neuroscience, 2023
Diffusion tensor imaging (DTI) studies have demonstrated white matter microstructural differences between the left and right hemispheres of the brain. However, the basis of these hemispheric asymmetries is not yet understood in terms of the biophysical ...

Housing Warmth/Coolness and Quietness Correlate With Whole‐Brain Fractional Anisotropy in Healthy Adults

Brain Health, EarlyView.
ABSTRACT Introduction Residential environments have been linked to brain structure, particularly in children, older adults, and clinical populations. However, little is known about how different dimensions of the housing environment relate to brain white matter microstructure in healthy adults, or whether specific environmental factors show stronger ...

Glymphatic dysfunction couples with cortical excitation–inhibition imbalance in epilepsy: Evidence from Rasmussen encephalitis

Epilepsia, EarlyView.
Cong Fu et al. demonstrate that glymphatic system dysfunction is linked to enhanced inhibitory cortical activity using diffusion MRI and EEG. These findings highlight a mechanistic link between perivascular fluid dynamics and neuronal activity, suggesting a role for glymphatic function in maintaining cortical stability in epilepsy.

Multimodal MRI and multiomics reveal high‐risk neurophenotype in brain‐gut circuits as therapeutic target for Crohn's disease

Interdisciplinary Medicine, EarlyView.
Through a translational framework combining prospective dual‐center clinical cohorts with dextran sulfate sodium‐induced colitis models, this work integrated advanced neuroimaging, multi‐omics and neuromodulation interventions to redefine the high‐risk neurophenotype as a sustained pathogenic driver rather than a mere phenomenon, proposing brain‐gut ...

Microstructure, length, and connection of limbic tracts in normal human brain development

Frontiers in Aging Neuroscience, 2014
The cingulum and fornix play an important role in memory, attention, spatial orientation and feeling functions. Both microstructure and length of these limbic tracts can be affected by mental disorders such as Alzheimer’s disease, depression, autism ...

Cross‐Vendor Validation of Proton Density Fat Fraction and T1 Mapping Using a Combined Proton Density Fat Fraction—T1 Phantom

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background In chronic liver disease, fat and fibroinflammatory changes often coexist. However, their biomarkers, proton density fat fraction (PDFF) and T1, are typically assessed separately. Their reproducibility under mutual confounding remains unclear.

Advanced diffusion MRI tract signatures in Alzheimer’s disease, dementia with Lewy bodies, and the FTD/PPA spectrum

NeuroImage
Alzheimer’s disease (AD), Dementia with Lewy bodies (DLB), frontotemporal dementia (FTD), and primary progressive aphasia (PPA) are heterogeneous neurodegenerative syndromes with overlapping clinical features and substantial societal burden.

Validation of automated DTI-ALPS and free water index as potential survival stratification markers in IDH-wildtype glioblastoma

Neuroradiology
Abstract Purpose Diffusion MRI–based indirect indices of neurofluid dynamics, such as diffusion tensor imaging along the perivascular space (DTI-ALPS) and extracellular free water (FW), have been reported to have prognostic implications in glioblastoma.

Transcranial Pulse Stimulation Enhances Dexterity in Parkinson's Disease: A Randomized Sham‐Controlled Trial

Movement Disorders, EarlyView.
Abstract Background Ultrasound‐based neuromodulation, capable of reaching deep brain areas with high precision, represents cutting‐edge technology in non‐invasive brain stimulation and is investigated as a novel treatment for neurological and psychiatric disorders, including Parkinson's disease (PD).
