Peripheral vision reaction time assessment to diagnose mild traumatic brain injury patients

A new test using peripheral vision reaction time could lead to earlier diagnosis and more effective treatment of mild traumatic brain injury, often referred to as a concussion, according to Peter J. Bergold, PhD, professor of physiology and pharmacology at SUNY Downstate Medical Center and corresponding author of a study published by the Journal of Neurotrauma. While …

Research shows positive outcome for early epilepsy surgery

There are important, long-term gains from hastening the processes around surgical interventions against epilepsy, before the disease has had too much negative impact on brain functions and patients’ lives. These are some of the findings of a thesis for which more than 500 patients were studied and followed up. “Around one third of those undergoing …

Tau protein as biomarker for predicting recovery time after concussion

Elevated levels of the brain protein tau following a sport-related concussion are associated with a longer recovery period and delayed return to play for athletes, according to a study published in Journal Neurology. The findings suggest that tau, which can be measured in the blood, may serve as a marker to help physicians determine an …

Deep brain magnetic stimulation provides precise and reliable activation of target neurons

Massachusetts General Hospital (MGH) researchers have developed what appears to be a significant improvement in the technology behind brain implants used to activate neural circuits responsible for vision, hearing or movement. The investigators, who are also affiliated with the Boston VA Healthcare System, describe their development of tiny magnetic coils capable of selectively activating target …

Magnetoencephalography and computational analysis to accurately diagnose concussions

Simon Fraser University researchers have found that high-resolution brain scans, coupled with computational analysis, could play a critical role in helping to detect concussions that conventional scans might miss. In a study published in PLOS Computational Biology, Vasily Vakorin and Sam Doesburg show how magnetoencephalography (MEG), which maps interactions between regions of the brain, could …

New biomarker based on expression of SHOX2 gene for predicting survival in Gliomas

Researchers at UT Southwestern Medical Center have found a new biomarker for glioma, a common type of brain cancer, that can help doctors determine how aggressive a cancer is and that could eventually help determine the best course of treatment. The findings are published in EBiomedicine. Researchers from the Harold C. Simmons Comprehensive Cancer Center found …

NeuroVascular Unit on a chip created to mimic functions of Blood-brain barrier

The blood-brain barrier is a network of specialized cells that surrounds the arteries and veins within the brain. It forms a unique gateway that both provides brain cells with the nutrients they require and protects them from potentially harmful compounds. This is an illustration of the neurovascular unit on a chip.Credit: Dominic Doyle, Vanderbilt University An …

Research shows meninges contain neural progenitor stem cells

In a cross-domain study directed by professor Peter Carmeliet, researchers discovered unexpected cells in the protective membranes that enclose the brain, the so-called meninges. These ‘neural progenitors’ – or stem cells that differentiate into different kinds of neurons – are produced during embryonic development. These findings show that the neural progenitors found in the meninges …

Signaling pathway that controls blood vessel development in brain has ability stop medulloblastoma, a cerebellar tumor.

A research team at the Krembil Research Institute has discovered that a signaling pathway which controls blood vessel development in the brain has the ability to stop brain tumor formation in animal models of medulloblastoma, the most common malignant brain tumor diagnosed in children. The findings, published in the journal eLife, are the first to …
