The research, at Washington University School of Medicine in St. Louis, is available online in the journal Cell.
RPB-supported researchers have made a significant discovery that might lead to the delay or prevention of the most common cause of blindness in the elderly: age-related macular degeneration (AMD). Patients who take the drug L-DOPA (for Parkinson Disease, Restless Legs or other movement disorders) are significantly less likely to develop AMD and, if they do, it is at a significantly later age.
Researchers have developed a brain imaging technique for patients whose epilepsy does not respond to drug treatment and are not candidates for seizure-relieving surgeries. The imaging technique, known as glutamate chemical exchange saturation transfer (GluCEST), images changes in glutamate levels in brain structures that identify the location of seizures not detected with conventional MRI.
Researchers from the University of Houston have analyzed brain activity data collected from more than 400 people who viewed an exhibit at the Menil Collection, offering evidence that useable brain data can be collected outside of a controlled laboratory setting. They also reported the first real-world demonstration of what happens in the brain as people observe artwork.
Brain scans of people in a coma may help predict who will regain consciousness, according to a study published in the November 11, 2015, online issue of Neurology®, the medical journal of the American Academy of Neurology.

The blood-brain barrier has been non-invasively opened in a patient for the first time. A team at Sunnybrook Health Sciences Centre in Toronto used focused ultrasound to enable temporary and targeted opening of the blood-brain barrier (BBB), allowing the more effective delivery of chemotherapy into a patient’s malignant brain tumor.
When it comes to preventing stroke, millions of Americans with irregular heartbeats face a choice: Take one of the powerful but pricey new pills they see advertised on TV, or a much cheaper 60-year-old drug can be a hassle to take, and doesn’t prevent stroke as well. It doesn’t seem like much of a contest -- until you do the math.
When peripheral nerves are damaged and their vital synaptic paths are disrupted, they have the ability to regenerate and reestablish lost connections. Using zebrafish, which are transparent at larval stages, the researchers identified key components that allows the nervous system to heal itself and literally obtain a whole new window into how axons regenerate.
The complexity of the neural activity we use to process visual images reflects the intricacy of those images, a team of NYU scientists has found. Their study offers new insights into how our brain extracts information about our natural surroundings from the light captured by our eyes.

The hippocampus, a brain structure known to play a role in memory and spatial navigation, is essential to one’s ability to recognize previously encountered events, objects, or people – a phenomenon known as recognition memory – according to new research from the departments of Neurosurgery and Psychology in the Perelman School of Medicine at the University of Pennsylvania. Their work is published in PNAS.
After a debate that has lasted more than 130 years, researchers at Georgetown University Medical Center have found that loss of speech from a stroke in the left hemisphere of the brain can be recovered on the back, right side of the brain. This contradicts recent notions that the right hemisphere interferes with recovery.
Multiple sclerosis, a debilitating neurological disease, is triggered by self-reactive T cells that successfully infiltrate the brain and spinal cord where they launch an aggressive autoimmune attack against myelin, the fatty substance that surrounds and insulates nerve fibers. In their latest study, published in the Nov. 2, 2015, advance online issue of Nature Immunology, researchers at the La Jolla Institute for Allergy and Immunology report that these disease-causing autoimmune T cells are lured into the nervous system by monocytes and macrophages, a subset of immune cells better known as the immune system’s cleanup crew.
The collection of vast stores of data that may unlock new information about the development of the brain as it transitions to adolescence from childhood will soon begin for neuroscientists in Nebraska with funding from the National Science Foundation (NSF).
Researchers have made another important step in the progress towards being able to block the development of multiple sclerosis (MS) and other autoimmune diseases.
