Long before Alzheimer’s disease can be diagnosed clinically, increasing difficulties building cognitive maps of new surroundings may herald the eventual clinical onset of the disorder, finds new research from Washington University in St. Louis.
A team of engineers, led by Washington University’s Lihong Wang and postdoctoral researcher Junjie Yao, found that by genetically modifying glioblastoma cancer cells to express BphP1 protein, derived from a bacterium commonly found in soil and water, they could clearly see tiny amounts of live cancer cells as deep as 1 centimeter in tissue using photoacoustic tomography.
The way our brains are wired may reveal a lot about us, according to new research co-authored by scientists at Washington University in St. Louis. For example, people with “positive” behavioral traits, such as sharp memories, many years of education and robust physical endurance, have stronger neural connections between certain brain regions than people with “negative” traits, such as smoking, aggressive behavior and a family history of alcohol abuse.
New research from Washington University in St. Louis has identified a novel learning and memory brain network that processes incoming information based on whether it’s something we’ve experienced previously or is deemed to be altogether new and unknown, helping us recognize, for instance, whether the face before us is that of a familiar friend or a complete stranger.
A team of Washington University students on the Medical Campus recently won top honors in the Neuro Startup Challenge, a biotech startup competition designed to commercialize promising brain-related discoveries of scientists at the National Institutes of Health (NIH).The team developed a business plan to commercialize a test for patients with multiple sclerosis.
Studying West Nile virus infection in mice, scientists at Washington University School of Medicine in St. Louis have shown that an antiviral compound tightens the blood-brain barrier, making it harder for the virus to invade the brain.
Fragile X syndrome, an inherited cause of autism and intellectual disability, can have consequences even for carriers of the disorder who don’t have full-blown symptoms. Researchers at Washington University School of Medicine in St. Louis have identified a potential target for treatment for fragile X carriers.
Stroke can lead to a wide range of problems such as depression and difficulty moving, speaking and paying attention. A new study led by Maurizio Corbetta, MD, at the School of Medicine has found evidence that stroke damage to “cables” buried inside the brain plays an important role in these impairments.
Highlighting a potential target in the treatment of multiple sclerosis (MS) and Alzheimer’s disease, new research suggests that triggering a protein found on the surface of brain cells may help slow the progression of these and other neurological diseases.
Why do so many of us cry at the movies? Why do we flinch when Rocky Balboa takes a punch? What’s really happening in our brains as we immerse ourselves in the lives being acted out on screen? These are the questions that Washington University in St. Louis neuroscientist Jeffrey M. Zacks, PhD, explores in his new book, “Flicker: Your Brain on Movies.”
