Science Daily: How the brain suppresses the act of revenge

Researchers have developed an economic game in which a participant is confronted with the fair behavior of one player and the unfair provocations of another player. They observed which areas were activated as the participant experienced unfairness and anger. Then scientists gave the participant the opportunity to take revenge. They thus identified the location in […]

SciTechDaily: New study shows dehydration alters human brain shape and activity

When dehydration strikes, part of the brain can swell, neural signaling can intensify, and doing monotonous tasks can get harder. With the help of brain scans and a simple, repetitive task to test responsiveness, exercise physiologists at the Georgia Institute of Technology studied volunteer subjects who sweated a lot and did not hydrate. The fluid […]

U.S. News & World Report: New concussion frontiers: Good news for brain injuries

The human brain is arguably the most complex and fascinating organ structure. About 3 pounds in weight, it contains approximately 100 billion neurons – which some say compares to the same number of stars in the Milky Way. The brain can also store up about 2.5 million gigabytes of data – our fancy smartphones offer […]

Health Day: Radiation for childhood brain tumor can hinder memory

Radiation therapy for the most common childhood brain tumor can cause memory problems, new research suggests. Specifically, it can leave young survivors struggling to create memories of recent personal events, the small study found. But survivors’ ability to recall ones that happened before radiation wasn’t affected. (August 21, 2018) Read the full article here

Medical Xpress: Alzheimer’s linked to the brain’s ‘garbage disposal service’

Researchers in South Australia have found a genetic link between Alzheimer’s disease and the endo-lysosomal system, a critical part of biological recycling machinery that maintains the health of brain cells. The researchers from the South Australian Health and Medical Research Institute (SAHMRI) say the findings give them a reason to focus on the endo-lysosomal system […]

New Atlas: Restoring brain plasticity may hold key to reversing age-related cognitive decline

Normal aging is commonly associated with a variety of mild sensory and cognitive declines. Separate to any acute dementia-related disease, this average age-related brain decline has been commonly thought to be caused by a slow reduction in the total number of brain cells. However, a new study from MIT’s Picower Institute for Learning and Memory […]

WBUR: The future of the reading brain in an increasingly digital world

Hours and hours of screen time. How much are digital distractions changing the way kids think, and even read? Maryanne Wolf, incoming director of UCLA’s Center for Dyslexia, Diverse Learners, and Social Justice. Most recently a professor of child development and public service at Tufts University, where she directed the Tufts Center for Reading and […]

Science Daily: New information on brain areas linked to tactile sense and metacognitive ability

Sense of touch provides information about textures, objects and physical forces acting on our body. Tactile information is also needed for successful execution of motor tasks such as grasping objects. The aim of Juha Gogulski’s doctoral thesis was to dissect the neural mechanisms underlying different levels of tactile processing in healthy subjects. (August 20, 2018) […]

Wired: Scientists are developing a unique identifier for your brain

Michaela Cordova, a research associate and lab manager at Oregon Health and Science University, begins by “de-metaling”: removing rings, watches, gadgets and other sources of metal, double-checking her pockets for overlooked objects that could, in her words, “fly in.” Then she enters the scanning room, raises and lowers the bed, and waves a head coil […]
