Yawning

open access: yesArquivos de Neuro-Psiquiatria, 1994
The ubiquitousness of normal yawning and the existence of abnormal yawning warrant an understanding of this reflex. Its mechanisms and functional role are not entirely known.

An analysis of clinical risk factors for adolescent scoliosis caused by spinal cord abnormalities in China: proposal for a selective whole-spine MRI examination scheme

open access: yesBMC Musculoskeletal Disorders, 2020
Background Approximately 80% of adolescent scoliosis cases are idiopathic, and some non-idiopathic scoliosis cases caused by spinal cord abnormalities are misdiagnosed as idiopathic scoliosis.

Abnormal Air-Righting Reflex in Striatal Rats

open access: yesThe Japanese Journal of Physiology, 2000
To understand dynamic postural control of the higher brain, we compared air-righting reflexes in various decerebrate rats. Post-operative 3-5 d thalamic and mesencephalic rats displayed almost similar righting movements as intact. However, in striatal animals, coordination of righting movements was disrupted.

Pathophysiology of knee jerk reflex abnormalities in L5 root injury [PDF]

open access: yes, 2015
Although the knee jerk reflex is mediated by the L3 and L4 nerve roots, evidence exists that altered knee jerk expression may occur with exclusively L5 radiculopathy.

Super‐Resolution Ultrasound Based Cell Tracking With Polymeric Nanobubbles

open access: yesAdvanced Materials, EarlyView.
This study presents a super‐resolution ultrasound platform for tracking cells in vivo. Biocompatible polymeric nanobubbles are used as highly echogenic intracellular labels. Following the injection of cells and microbubbles, ultrasound localization microscopy (ULM) can dynamically match the microvascular architecture and individual cell trajectories ...

An abnormal neural reflex plays a role in causing syncope in sinus bradycardia

open access: yes, 1993
Objectives. This study Investigates the rote of an abnormal neural reflex in causing syncope in patients with sinus bradycardia.Background. Syncope is commonly considered an indication of severity in sinus bradycardia.

Flexible Implantable Silicon Carbide Multi‐Electrode Array (MEA) for Cell Multichannel Recording and Cell Ablation

open access: yesAdvanced Materials Technologies, EarlyView.
Flexible silicon carbide (SiC) microelectrode arrays enable high‐fidelity, multichannel cell extracellular recording and precise localized ablation. SiC has been extensively evaluated to persist long‐term in chronic physiological conditions while remaining robust, with excellent electrical and electrochemical stability.

GPR124 Alleviates Blood–Brain Barrier Disruption by Enhancing Microvascular Endothelial Function after Traumatic Brain Injury

open access: yesAdvanced Science, EarlyView.
Our study reveals the protective role of GPR124 in maintaining BBB integrity and promoting neurological recovery following TBI. It makes a significant contribution by uncovering a novel molecular interaction between GPR124 and FGFBP1 and linking this to activation of the Wnt/β‐catenin signaling pathway in vascular repair mechanisms.

The hyperekplexias and their relationship to the normal startle reflex.

open access: yes, 1991
The startle response to unexpected auditory and somaesthetic stimulation was studied in 8 patients with hereditary or symptomatic hyperekplexia. It was abnormal in its resistance to habituation and in its exaggerated motor response.
