The video head impulse test [PDF]

Neurology, 2009
The head impulse test (HIT) is a useful bedside test to identify peripheral vestibular deficits. However, such a deficit of the vestibulo-ocular reflex (VOR) may not be diagnosed because corrective saccades cannot always be detected by simple observation.

Collision‐Resilient Winged Drones Enabled by Tensegrity Structures

Advanced Robotics Research, EarlyView.
Based on structures of birds such as the woodpeck, this article presents the collision‐resilient aerial robot, SWIFT. SWIFT leverages tensegrity structures in the fuselage and wings which allow it to undergo large deformations in a crash, without sustaining damage. Experiments show that SWIFT can reduce impact forces by 70% over conventional structures.

Video head impulse test – „očni EKG“ [Video head impulse test – eye]

Liječnički vjesnik, 2017
In the diagnosis of acute vestibular syndrome (AVS) the key part is a quick and reliable differentiation between peripheral and central etiologies. Video head impulse test (vHIT) is a new method that is based on the examination of rotational vestibulo-ocular reflex. vHIT has demonstrated high specificity for peripheral vestibular damage.

The GLP1R Agonist Semaglutide Inhibits Reactive Astrocytes and Enhances the Efficacy of Neural Stem Cell Transplantation Therapy in Parkinson's Disease Mice

Advanced Science, EarlyView.
Compared to transplantation of neural stem cells (NSCs) alone, the combined treatment of NSCs with semaglutide more effectively improves motor dysfunction in Parkinson's disease (PD) mice. This synergistic effect may result from semaglutide's ability to suppress microglial activation, thereby preventing the transformation of resting astrocytes into ...

Targeting ROCK2 to Restore Epileptic Synaptic Networks via Mitophagy Activation: Insights from Translational Imaging of SV2A In Vivo

Advanced Science, EarlyView.
By integrating synaptic vesicle glycoprotein 2A PET imaging and transcriptomics, this study identifies Rho‐associated protein kinase 2 (ROCK2) as a critical regulator of synaptic network dysfunction in temporal lobe epilepsy. Pharmacological ROCK2 inhibition restores synaptic density and enhances mitophagy, thereby reducing seizures and neuronal damage.

Dimensionality and dynamics in the behavior of C. elegans [PDF]

, 2007
A major challenge in analyzing animal behavior is to discover some underlying simplicity in complex motor actions. Here we show that the space of shapes adopted by the nematode C.

Synaptic Dysfunction in the Anterior Cingulate Cortex Underlies Pain‐Anxiety Comorbidity in a Mandibular Asymmetry Mouse Model

Advanced Science, EarlyView.
This study establishes a mandibular asymmetry (MA) mouse model that recapitulates chronic orofacial pain and anxiety comorbidity. Anterior cingulate cortex (ACC) hyperactivation and synaptic dysfunction are identified as central neural mechanisms underlying these pathologies, with chemogenetic inhibition of ACC CaMKII+ neurons effectively reversing ...
