Frontiers in Neurology, 2019 • March 26, 2019
This study demonstrates the feasibility of using functional ultrasound (fUS) imaging to monitor spinal cord hemodynamic responses to epidural electrical stimulation (SCS) in animal models. The researc...
KEY FINDING: fUS can detect spinal cord hemodynamic responses to epidural electrical stimulation (SCS) in both rat and swine models.
Neurology, 2019 • June 11, 2019
This study assessed the predictive value of midsagittal tissue bridges on MRI for sensorimotor recovery after cervical SCI. The width of dorsal tissue bridges correlated with sensory recovery and SEP ...
KEY FINDING: Greater width of dorsal midsagittal tissue bridges was associated with being sensory incomplete at 12 months, shorter SEP latencies, and greater SEP amplitudes.
Sensors, 2012 • January 31, 2012
This review paper summarizes the state-of-the-art of brain-computer interfaces (BCIs), focusing on the different stages of a BCI system: signal acquisition, preprocessing, feature extraction, classifi...
KEY FINDING: Electroencephalography (EEG) is the most widely used neuroimaging modality in BCIs because of its high temporal resolution, low cost, and portability.
J Neurol Neurosurg Psychiatry, 2012 • June 1, 2012
This study investigates the relationship between axonal integrity in the corticospinal tract (CST), spinal cord area, and cortical reorganization in subjects with traumatic spinal cord injury (SCI) us...
KEY FINDING: Diffusion tensor imaging showed significant differences in the CST of SCI subjects compared to controls in areas such as the pyramids, internal capsule, cerebral peduncle, and hand area.
The Neuroscientist, 2012 • April 1, 2012
Traumatic SCI induces anatomical and functional changes in both the spinal cord and brain. Neuroimaging can detect anatomical changes in the spinal cord, such as cyst formation and atrophy, and in the...
KEY FINDING: Spinal cord atrophy, measured by a decline in cross-sectional area, correlates with the degree of clinical impairment and hand function in chronic SCI patients.
Brain Stimul., 2014 • March 1, 2014
This study investigates the effects of motor cortex stimulation (MCS) on cortical responses to noxious stimuli in rats with spinal cord lesions (SCL). The results show that MCS suppresses evoked blood...
KEY FINDING: MCS significantly suppressed evoked blood oxygen dependent signals in the primary somatosensory cortex and the prefrontal cortex.
CNS Neuroscience & Therapeutics, 2014 • April 1, 2014
This letter to the editor presents a case of superficial siderosis (SS) in a 66-year-old man, linked to a thoracic disc herniation and associated dural injury. The patient exhibited symptoms including...
KEY FINDING: The patient presented with leg weakness, gait impairment, hearing loss, and urinary incontinence.
Journal of Medical Case Reports, 2022 • November 30, 2022
This case report describes an 81-year-old man who developed unilateral delayed post-hypoxic leukoencephalopathy (DPHL) following a dissection-related occlusion of the left carotid artery. The patient ...
KEY FINDING: Clinical symptoms suggestive of delayed post-hypoxic leukoencephalopathy (DPHL) can be observed in very rare cases following successful revascularization therapy in large vessel occlusions, causing acute ischemic stroke.
PLoS ONE, 2016 • August 25, 2016
This study compares three different dMRI protocols applied to investigate the microstructure of both gray (GM) and white matter (WM) in the lumbar region of the mouse spinal cord. The protocols were c...
KEY FINDING: Intermediate features (12 directions, b = 1200 s/mm2) provided the overall minimum inter- and intra-subject variability in most cases.
The Open Neuroimaging Journal, 2016 • October 16, 2016
The study investigates the use of manganese-enhanced MRI (MEMRI) as a non-invasive tool to assess the severity of spinal cord injury (SCI) in rat models. MEMRI results correlated strongly with SCI sev...
KEY FINDING: MEMRI ratios were significantly lower in transection and hemisection groups compared to controls, indicating reduced neuronal activity in injured spinal cords.
