Subvoxel Quantitative Susceptibility Decomposition Reveals Distinct Paramagnetic and Diamagnetic Alterations in PD
Impact: χ-separation
decomposes subvoxel magnetic susceptibility sources, enabling in vivo
differentiation between iron deposition and myelin alterations in Parkinson’s
disease, thereby providing new quantitative biomarkers for neurodegeneration
and cognition-related pathophysiology.

fMRI Connectivity-Based Clustering of PVNH to guide SEEG implantation
Impact: Clustering
periventricular nodular heterotopia based on connectivity patterns to other
brain regions may help guide stereo-EEG (SEEG) implantation planning, ensuring that
each cluster and its connected regions are sampled by SEEG to avoid omission of
potential epileptogenic areas.

Low frequency fourth ventricle cerebrospinal fluid inflow and vascular reactivity in Cerebral Amyloid Angiopathy
Impact: Visual stimulation-evoked
vascular reactivity is impaired in patients with Cerebral Amyloid Angiopathy. It
remains unclear whether reduced vascular reactivity is linked to impaired
cerebrospinal fluid dynamics. Interrogating this relationship with non-invasive
MRI will help with our understanding of these phenomena.

Resting state functional magnetic resonance imaging study comparing tremor-dominant Parkinson’s disease and essential tremor
Impact: To enhance the understanding of spontaneous
brain activity patterns of tremor-dominant Parkinson’s
disease (TD) and essential tremor (ET), and to
facilitate more effective differentiation between these two conditions

Global functional connectivity is altered in cognitively intact APOE ε4 carriers
Impact: Our findings in a longitudinal sample of cognitively intact APOE ε4 carriers
add to the literature on resting state functional connectivity changes in
preclinical Alzheimer’s disease. These early changes may point to mechanisms of
AD-related cognitive decline.

White Matter and Glymphatic Alterations in DoC: Links to Consciousness and Prognosis
Impact: TBI may cause brain structural damage, impair glymphatic function, and subsequently affect patients' levels of consciousness. These findings further indicate that glymphatic dysfunction could play an important role in the pathogenesis and prognosis of disorders of consciousness.

Predicting Treatment Response to Transcutaneous Auricular Vagus Nerve Stimulation in Patients with Insomnia
Impact: Transcutaneous auricular vagus nerve stimulation (taVNS) may alleviate insomnia by lowering functional connectivity (FC) between salience and task‑positive networks and within the cingulo‑opercular network. Baseline left insula‑visual/auditory FC could predict taVNS treatment response.

Neurotransmitter Alterations and Glymphatic System Dysfunction in Chronic Insomnia Co-morbid with Major Depressive Disorder
Impact: Patients with insomnia and comorbid depression show distinct patterns of glymphatic dysfunction and neurotransmitter imbalance. Coexisting depression may worsen glymphatic impairment, highlighting the need for early intervention and cautious use of GABA receptor agonists in treatment.

Investigation of Metabolite Alterations in MELAS patient
Impact: The imbalance between glutamate and glutamine, along with decreased tNAA and myo-inositol concentrations, may serve as potential biomarkers for identifying the acute phase of MELAS, offering new perspectives for its diagnosis and clinical management.
