Altered Neurovascular Coupling Dynamics During Dobutamine-Induced Acute Stress. [PDF]

Brain Behav
ABSTRACT Background Neurovascular coupling (NVC) is essential for regulating brain metabolism and energy supply and may be altered under acute stress. This study aimed to investigate how acute stress induced by dobutamine affects NVC. Materials and methods This study enrolled 38 healthy participants undergoing a resting‐state fMRI scan and an arterial ...

Posture-Related Regional Homogeneity Abnormalities in Cerebral Small Vessel Disease: A Multi-Position MRI Study. [PDF]

CNS Neurosci Ther
Patients with CSVD showed higher upright ReHo in anterior cingulate gyrus (ACG) than NCs, and supine‐upright comparison revealed widespread ReHo alterations. Upright ACG ReHo and posture‐related ReHo changes in the hippocampus, putamen, and calcarine cortex were associated with poorer cognition and greater CSVD burden, suggesting that upright imaging ...

Dual Transcranial Direct Current Stimulation Modulates Hierarchical Functional Network Organization in Post-Stroke Cognitive Impairment: A Randomized Controlled Trial. [PDF]

CNS Neurosci Ther
Bilateral DLPFC dual‐tDCS significantly promotes cognitive recovery by modulating the rs‐fMRI hierarchical organization of functional brain networks, ranging from regional synchrony, distant regions connectivity and global network topological integration.

ALFF and ReHo Mapping Reveals Different Functional Patterns in Early- and Late-Onset Parkinson’s Disease [PDF]

Frontiers in Neuroscience, 2020
Heterogeneity between late-onset Parkinson's disease (LOPD) and early-onset Parkinson's disease (EOPD) is mainly reflected in the following aspects including genetics, disease progression, drug response, clinical manifestation, and neuropathological change.

Association of Left Angular Gyrus-Right Middle Frontal Gyrus Functional Connectivity With Insomnia Severity in Major Depressive Disorder: Evidence From the DIRECT Consortium. [PDF]

CNS Neurosci Ther
Preferential alterations in insomnia‐related AG–MFG connectivity in MDD highlight sleep‐associated neural mechanisms, although disentangling these connectivity changes from depression severity remains challenging. Local aberrations in regional brain function primarily differentiate patients with MDD from healthy controls.

Diurnal Variations and Test-Retest Reliability of Resting-State Functional MRI Metrics. [PDF]

Hum Brain Mapp
Regional homogeneity (ReHo) exhibited the highest within‐day reliability, whereas fractional amplitude of low‐frequency fluctuations (fALFF) showed the lowest. The limbic network demonstrated the lowest reliability among the networks, with a notable mid‐morning dip at 10:00. ABSTRACT Resting‐state fMRI (rs‐fMRI) is widely used to assess intrinsic brain
