A new study by MIT and Boston University neuroscientists finds that the dynamic interplay of different brain wave frequencies, rather than dedicated circuitry, appears to govern the brain's knack for highlighting what's surprising and downplaying what's predictable.
Like humans who can instantly tell which friend or relative is calling by the timbre of the person's voice, zebra finches have a near-human capacity for language mapping.
More than three decades after they were found to have elevated blood lead levels as children, a group of middle-aged adults were found to have some small but significant changes in brain structure that corresponded to their dose of lead exposure in early life. MRI scans at age 45 revealed some small but significant changes in the brains of the people who had higher lead exposures measured at age 11.
Psychologists are hoping the UNSW Face Test will help unearth more of Australia's top performers in facial recognition, known as super-recognisers.
A study published today in The Journal of Nutrition showed that mothers' vitamin D levels during pregnancy were associated with their children's IQ, suggesting that higher vitamin D levels in pregnancy may lead to greater childhood IQ scores.
Scientists at Center for BrainHealth® worked with researchers across the world to develop a science-based plan that could help the economy recover and prevent similar collapses in the future. The Brain Capital Grand Strategy is an economic reimagination wherein organizations invest in employees' brain health as a critical, measurable asset. Improving brain health helps people tap into their brain's limitless potential, catalyze innovative thinking and improve their productivity, in turn strengthening the transforming economy.
Researchers studied the effects of a 12-week exercise regimen on 148 active-duty Air Force airmen, half of whom also received a twice-daily nutrient beverage that included protein; the omega-3 fatty acid, DHA; lutein; phospholipids; vitamin D; B vitamins and other micronutrients; along with a muscle-promoting compound known as HMB. Both groups improved in physical and cognitive function, with added gains among those who regularly consumed the nutritional beverage, the team reports.
A team of Russian researchers with the participation of a leading researcher at HSE University, Ekaterina Pechenkova, found that during group problem solving the components of the social brain are co-activated, but they do not increase their coupling during cooperation as would be suggested for a holistic network. The study was published in Frontiers in Human Neuroscience.
Supplements that claim to improve mental focus and memory may contain unapproved pharmaceutical drugs and in potentially dangerous combinations and doses, according to a new study published in the September 23, 2020, online issue of Neurology® Clinical Practice, an official journal of the American Academy of Neurology. Researchers found five such drugs not approved in the United States in the supplements they examined. The supplements are sometimes called "nootropics," "smart drugs" or "cognitive enhancers."
A study led by UC Davis Health researchers uncovered that even one severe episode of diabetic ketoacidosis (DKA) in children newly diagnosed with type 1 diabetes is linked to cognitive problems; and among children with a previous diagnosis, repeated DKA exposure predicted lower cognitive performance after accounting for glycemic control.
