Neural Plasticity, 2021 • September 17, 2021
This study aimed to determine the frequency and associated risk factors of asymmetrical prominent veins (APV) in patients with acute ischemic stroke (AIS) within 12 hours of symptom onset. The study f...
KEY FINDING: The frequency of high APV (volume ≥10 mL) was 46.05% in patients with AIS within 12 hours of symptom onset.
Frontiers in Neurology, 2021 • November 30, 2021
The study characterized four stages of CSVD severity in SHRSP at different time points, ranging from pre-hypertensive to advanced CSVD. Quantitative analyses of brain MRI enable identification of in v...
KEY FINDING: SHRSP showed a significantly higher prevalence of small subcortical hyperintensities on T2w imaging that progressed in size and frequency with aging compared to WKY controls.
Top Spinal Cord Inj Rehabil, 2022 • April 1, 2022
This prospective study examined the utility of diffusion tensor imaging (DTI) as a biomarker for assessing microstructural changes in pediatric spinal cord injury (SCI). The study compared DTI metrics...
KEY FINDING: A significant positive association was found between fractional anisotropy (FA) and upper extremity muscle strength in participants with SCI, indicating that higher muscle strength is associated with higher FA values.
Am J Psychiatry, 2022 • September 1, 2022
This study investigated the predictive capacity of persistent derealization, a type of dissociation, for adverse psychiatric outcomes following acute trauma. The research found that derealization, mea...
KEY FINDING: Derealization was associated with increased activity in the ventromedial prefrontal cortex (vmPFC) during an emotion reactivity task.
Translational Psychiatry, 2022 • August 22, 2022
This study investigated the role of the ventral visual stream (VVS) in PTSD using multimodal MRI data from trauma-exposed individuals. A structural covariance network (SCN) within the VVS was identifi...
KEY FINDING: A structural covariance network (SCN) of the ventral visual stream (VVS) was identified, and its strength was positively associated with PTSD symptoms two weeks after trauma.
Frontiers in Neurology, 2019 • November 1, 2019
The study proposes a distance-based neurorehabilitation evaluation method using rs-fMRI and linear SVM to monitor brain function changes after a rehabilitation program. The method involves training an...
KEY FINDING: The classifier successfully separated patients and healthy controls based on their resting-state fMRI data.
Brain Communications, 2023 • December 19, 2022
This study introduces a neuroimaging and analysis protocol to identify spinal cord levels at the lumbosacral enlargement, assess anatomical variability, locate epidural stimulation electrodes, and lin...
KEY FINDING: The length of the spinal column and spinal cord, location of the conus tip, and the relationship between spinal cord and vertebral levels at the lumbosacral enlargement vary across individuals.
Neural Plasticity, 2020 • March 10, 2020
This study investigated the reorganization of insular subregions in individuals suffering from neuropathic pain (NP) after incomplete spinal cord injury (ISCI) to disclose the underlying mechanism of ...
KEY FINDING: Compared to ISCI individuals without neuropathic pain, those with neuropathic pain showed increased functional connectivity between the left posterior insula and the right cerebellum VIIb and VIII, as well as Brodmann area 37.
Neuroimage, 2020 • August 15, 2020
This study used fMRI to quantitatively assess the spatial distribution of spinal cord activity from left- and right-sided tactile stimulation of the lateral shoulders and dorsal third digits of the ha...
KEY FINDING: Tactile stimulation resulted in activity localized primarily to the ipsilateral hemicord, with the left- and right-sided stimuli having more activation in the respective ipsilateral hemicord.
NeuroImage: Clinical, 2020 • July 25, 2020
The study investigated alterations in brain activity, specifically using power spectral density (PSD) analysis of resting-state fMRI, in patients with spinal cord injury (SCI) experiencing neuropathic...
KEY FINDING: Lower PSD values in supplementary motor and medial prefrontal areas were associated with greater pain severity and poorer postural balance and mobility in patients with SCI.
