after a Central Nervous System Injury (New York – March 2, 2020) Plexin-B2, an axon guidance protein in the central nervous system (CNS), plays an important role in wound healing and neural repair following spinal cord injury (SCI), according to research conducted at the Icahn School of Medicine at Mount Sinai and published today in Nature Neuroscience.
A team of researchers at the University of Arizona has found that low-intensity ultrasound waves directed at a particular region of the brain’s prefrontal cortex in healthy subjects can elevate mood, and decrease connectivity in a brain network that has been shown to be hyperactive in psychiatric disorders. The method uses transcranial focused ultrasound (‘tFUS’), a painless, non-invasive technique to modulate brain function comparable to transcranial magnetic stimulation (‘TMS’), and transcranial direct current stimulation (‘tDCS’). This study shows, for the first time, a correlation between tFUS-induced mood enhancement, and reorganization of brain circuits.
Announces the theme and contents of the March 2020 issue of Neurosurgical Focus, an online peer-reviewed journal.
The National Science Foundation has recognized Fabrizio Sergi, assistant professor of biomedical engineering at the University of Delaware, with its CAREER award to support fundamental research in motor control. His work is seeking to help those with movement disorders and identify robot-based interventions.
Speech and music are two fundamentally human activities that are decoded in different brain hemispheres. A new study used a unique approach to reveal why this specialization exists.
New research by University of Wisconsin–Madison scientists reveals how a cellular filament helps neural stem cells clear damaged and clumped proteins, an important step in eventually producing new neurons.
Nanoparticles have been used to treat disease for decades, but scientists are now learning more about how they move through human tissue. PECASE honoree and NIGMS grantee Elizabeth Nance is enlisting minds across different scientific fields to solve the challenge of using nanoparticles to target the right site within the body to increase the effectiveness of treatments for newborn brain injury.
Parkinson’s disease researchers have used gene-editing tools to introduce the disorder’s most common genetic mutation into marmoset monkey stem cells and to successfully tamp down cellular chemistry that often goes awry in Parkinson’s patients.
Changing global temperatures could mean lost productivity for workers around the globe, according to Nancy Sicotte, MD, chair of the Department of Neurology at Cedars-Sinai.
New research shows brain imaging may be able to predict when a blood test known as a liquid biopsy would or would not produce clinically actionable information
An international team of scientists, led by UC San Diego researchers, has developed a new, multi-sensor tool that measures subtle changes in multiple sclerosis patients, allowing physicians to more frequently and more quickly respond to changes in symptoms or patient condition.
Having health issues such as smoking, high cholesterol or a high body mass index (BMI) in your 20s may make you more likely to have problems with thinking and memory skills and even the brain’s ability to properly regulate its blood flow, according to a preliminary study released today that will be presented at the American Academy of Neurology’s 72nd Annual Meeting in Toronto, Canada, April 25 to May 1, 2020.
Scientists from the Uniformed Services University (USU), Emory University and the University of Vermont have found that cigarette smoking is linked to increased lesions in the brain’s white matter, called white matter hyperintensities. White matter hyperintensities, detected by MRI scan, are associated with cognitive decline and Alzheimer's disease. These findings may help explain the link between smoking and increased rates of dementia and other forms of cognitive decline.
The deadly brain cancer glioblastoma (GBM) is often resistant to chemotherapy and radiation, but new research shows targeting stromal cells – the cells that serve as the connective tissue of the organs – may be an effective way of overcoming that resistance
Rates of diagnosed attention deficit-hyperactivity disorder (ADHD) in veterans receiving care in the VA health system more than doubled during the past decade, reports a study in the March issue of Medical Care. The journal is published in the Lippincott portfolio by Wolters Kluwer.
The naturally occurring molecule N-acetylcysteine (NAC) shows benefit in a clinical trial for multiple sclerosis.
Misuse of prescription benzodiazepines (such as alprazolam or Xanax, and diazepam or Valium) has been linked to nicotine use. Evidence of how nicotine “sets up” a craving for benzodiazepines — often called “benzos” — in animal laboratory studies has been published in the open access journal eNeuro.
Pingpong may hold promise as a possible form of physical therapy for Parkinson’s disease. People with Parkinson’s who participated in a pingpong exercise program once a week for six months showed improvement in their Parkinson’s symptoms, according to a preliminary study released today that will be presented at the American Academy of Neurology’s 72nd Annual Meeting in Toronto, Canada, April 25 to May 1, 2020.
Researchers at the University of Maryland School of Medicine (UMSOM) found that targeting overactive immune cells in the brain with an experimental drug could limit brain cell loss and reverse cognitive and motor difficulties caused by traumatic brain injury (TBI).
