The journal is published by Wolters Kluwer.

They say you can’t teach an old dog new tricks. The same can be said of the adult brain. Its connections are hard to change, while in children, novel experiences rapidly mold new connections during critical periods of brain development.
A team of NYU neuroscientists has identified a part of the brain exclusively devoted to processing speech, helping settle a long-standing debate about role-specific neurological functions.
In a study using functional magnetic resonance imaging, Virginia Tech Carilion Research Institute scientists found that our inherent risk-taking preferences affect how we view and act on information from other people.
In the first study of its kind, former National Football League (NFL) players who lost consciousness due to concussion during their playing days showed key differences in brain structure later in life.
Studies have shown that individuals with hearing loss or who are listening to degraded speech – think of a loud room -- have greater difficulty remembering and processing the spoken information than individuals who heard more clearly. Now researchers are investigating whether listening to accented speech similarly affects the brain's ability to process and store information. Their preliminary results suggest that foreign-accented speech, even when intelligible, may be slightly more difficult to recall than native speech.
Researchers have found that an antiviral compound may protect the brain from invading pathogens. Studying West Nile virus infection in mice, scientists at Washington University School of Medicine in St. Louis showed that interferon-lambda tightens the blood-brain barrier, making it harder for the virus to invade the brain.

Researchers at Mayo Clinic in Florida have developed a mouse model that exhibits the neuropathological and behavioral features associated with the most common genetic form of amyotrophic lateral sclerosis (ALS or Lou Gehrig’s disease) and frontotemporal dementia (FTD), which are caused by a mutation in the C9ORF72 gene.
Adults over 50 who have persistent symptoms of depression may have twice the risk of stroke as those who do not, according to a new study led by researchers at Harvard T.H. Chan School of Public Health. Researchers found that stroke risk remains higher even after symptoms of depression go away, particularly for women.
The 12th World Congress of the International Neuromodulation Society scientific program, from June 8 - 11, 2015 in Montreal, will present landmark studies about neurostimulation therapy and investigations of potential breakthroughs.
Chewing, breathing, and other regular bodily functions that we undertake “without thinking” actually do require the involvement of our brain, but the question of how the brain programs such regular functions intrigues scientists. Arlette Kolta, a professor at the University of Montreal’s Faculty of Dentistry, has shown that astrocytes play a key role. Astrocytes are star-shaped glial cells in our brain. Glial cells are not neurons – they play a supporting role.
MINNEAPOLIS – A new study suggests that medical marijuana pills may not help treat behavioral symptoms of dementia, such as aggression, pacing and wandering. The research is published in the May 13, 2015, online issue of Neurology®, the medical journal of the American Academy of Neurology. However, researchers did find that the drug dosage used in the clinical trial was safe and well-tolerated.
Few hospitals around the world routinely use MRI first-line for acute stroke diagnosis because of treatment delay concerns. This is the first study to report that, by applying “lean” process interventions, it is feasible to use MRI before administering a life-saving drug to stroke patients within 60 minutes of hospital arrival.
Supercomputing resources at Oak Ridge National Laboratory will support a new initiative designed to advance how scientists digitally reconstruct and analyze individual neurons in the human brain.
If you walk into a dark room, you can still find your way to the light switch. That’s because your brain keeps track of landmarks and the direction in which you are moving. Fruit flies also boast an internal compass that works when the lights go out, scientists at the Howard Hughes Medical Institute’s Janelia Research Campus have discovered. Their findings suggest that dissecting how fruit flies navigate through the world could help researchers understand how humans and other mammals perform similar tasks.
Smokers who are able to quit might actually be hard-wired for success, according to a study from Duke Medicine. The study, published in Neuropsychopharmacology, showed greater connectivity among certain brain regions in people who successfully quit smoking compared to those who tried and failed.

Scientists at The Scripps Research Institute have discovered that a brain protein has a key role in controlling binge drinking in animal models.
Therapies that specifically target mutations in a person’s cancer have been much-heralded in recent years, yet cancer cells often find a way around them. To address this, researchers at University of California, San Diego School of Medicine and Moores Cancer Center identified a promising combinatorial approach to treating glioblastomas, the most common form of primary brain cancer. The study published May 5 by Oncotarget.
The study provides an explanation for why many people with even very trivial head injuries, or even injuries to other parts of their bodies, experience incapacitating post-concussion like syndromes.
Researchers at the University of Illinois at Chicago have determined the molecular structure of one of the proteins in the fine fibers of the brain plaques that are a hallmark of Alzheimer’s disease. This molecule, called amyloid beta-42, is toxic to nerve cells and is believed to provoke the disease cascade.
Just like cameras with an autostabilization feature, our eyes execute an imperceptible reflex that prevents our vision from blurring when we are in motion. But before the reflex can work, the axons of specialized nerve cells must find their way from the retina to the correct part of the brain. New research describes how those axons accomplish this feat.
Vanderbilt biologists have localized the seasonal light cycle effects that drive seasonal affective disorder to a small region of the brain called the dorsal raphe nucleus.
Researchers at University of California, San Diego School of Medicine and Shiley Eye Institute have identified the molecular “glue” that builds the brain connections that keep visual images clear and still, even as objects or your eyes move. Using mouse models, the researchers demonstrate that image stabilization depends upon two proteins, Contactin-4 and amyloid precursor protein, binding during embryonic development.
