BBC: Dyslexia link to eye spots confusing brain, say scientists

French scientists say they may have found a potential cause of dyslexia which could be treatable, hidden in tiny cells in the human eye. In a small study they found that most dyslexics had dominant round spots in both eyes – rather than in just one – leading to blurring and confusion. (October 18, 2017) […]

Health Imaging: Brain, spinal cord MR imaging helps ID MS risk in children

New research from Yale University’s School of Medicine shows scans of the brain and spinal cord can be key to identifying changes in brain activity that can lead to multiple sclerosis (MS) in children. The researchers, led by Naila Makhani, MD MPH, assistant professor of pediatrics and director of the Pediatric MS Program at Yale, […]

NPR: Search of DNA in dogs, mice and people finds 4 genes linked to OCD

People who have obsessive-compulsive disorder can get trapped inside a thought. It repeats itself, like a stuck song. Did I lock the door? Is that doorknob clean enough to touch? I better wash my hands again — and again. The biology underpinning this loop remains murky to scientists, but scientists are beginning to sniff out […]

Science Blog: Dogs are more expressive when someone is looking

Dogs produce more facial expressions when humans are looking at them, according to new research from the University of Portsmouth. Scientists at the University’s Dog Cognition Centre are the first to find clear evidence dogs move their faces in direct response to human attention. Dogs don’t respond with more facial expressions upon seeing tasty food, […]

Medical News Today: When it comes to rewards, the brain prefers not to wait

Our brains assess the pros and cons of thousands of situations every day, and this mostly occurs without our conscious brains being involved. Breaking research looks at how long waiting times influence reward pathways. The nucleus accumbens is a tiny group of cells that lie deep in the center of our brains, and it releases […]

Science Daily: Nature or nurture? Innate social behaviors in the mouse brain

Adult male mice have a simple repertoire of innate, or instinctive, social behaviors: When encountering a female, a male mouse will try to mate with it, and when encountering another male, the mouse will attack. The animals do not have to be taught to perform these behaviors. This has led to the widespread presumption among […]

Medical Xpress: Team finds training exercise that boosts brain power

One of the two brain-training methods most scientists use in research is significantly better in improving memory and attention, Johns Hopkins University researchers found. It also results in more significant changes in brain activity. Though this exercise didn’t make anyone smarter, it greatly improved skills people need to excel at school and at work. These […]

Harvard Health: Women’s stroke rate stubbornly steady

Men are less likely to have strokes than they were 10 years ago, but the risk for women has stayed about the same, according to a study of stroke data from Ohio and Kentucky, published online on August 21 by Neurology. The question is, why? “This study raises important concerns about the lack of decline […]

Health Imagine: Brain imaging for infants may help detect development of autism

New research from JAMA indicates that an MRI can detect signs of autism developing in infants during a “presymptomatic period.” Published online Oct. 3, the study, conducted by Tracy Hampton, PhD, suggests early brain scans in infants earlier than 24 months could predict signs of autism spectrum disorder (ASD). “The findings point to a noninvasive […]

News-Medical: New imaging system offers better way to monitor brain changes from Alzheimer’s in mouse models

An estimated 5.5 million Americans live with Alzheimer’s disease, a type of dementia that causes problems with memory, thinking and behavior. Although treatments can slow the worsening of symptoms, scientists are still working to better understand the neurodegenerative disease so that curative and preventative medicines can be developed. A new imaging system could help speed […]
