CNN: Stress might lead to memory loss and brain shrinkage, study says

Listen up, gen-Xers and millennials, and, well, everybody who has a brain. If you live a high-stress life, you could have memory loss and brain shrinkage before you turn 50, according to a study published Wednesday in the journal Neurology. “Higher levels of cortisol, a stress hormone, seem to predict brain function, brain size and […]

Medical Xpress: Mind’s quality control center found in long-ignored brain area

The cerebellum can’t get no respect. Located inconveniently on the underside of the brain and initially thought to be limited to controlling movement, the cerebellum has long been treated like an afterthought by researchers studying higher brain functions. But researchers at Washington University School of Medicine in St. Louis say overlooking the cerebellum is a […]

News-Medical: Neurons in the brain’s primary visual cortex can reliably detect straight lines

Single neurons in the brain’s primary visual cortex can reliably detect straight lines, even though the cellular makeup of the neurons is constantly changing, according to a new study by Carnegie Mellon University neuroscientists, led by Associate Professor of Biological Sciences Sandra Kuhlman. The study’s findings, published in Scientific Reports on Oct. 16, lay the […]

New York Times: Even a 10-minute walk may be good for the brain

Ten minutes of mild, almost languorous exercise can immediately alter how certain parts of the brain communicate and coordinate with one another and improve memory function, according to an encouraging new neurological study. The findings suggest that exercise does not need to be prolonged or intense to benefit the brain and that the effects can […]

Science Daily: Study reveals how the brain overcomes its own limitations

Imagine trying to write your name so that it can be read in a mirror. Your brain has all of the visual information you need, and you’re a pro at writing your own name. Still, this task is very difficult for most people. That’s because it requires the brain to perform a mental transformation that […]

News-Medical: How does our brain perceives the environment?

Nearly 30 years ago, scientists demonstrated that visually recognizing an object, such as a cup, and performing a visually guided action, such as picking the cup up, involved distinct neural processes, located in different areas of the brain. A new study shows that the same is true for how the brain perceives our environment — […]

Science Daily: Wishful thinking is rewarded

We make judgements quite rationally or “by the gut.” Not only experience and relevant information play an important role, but also our preferences. A study by the Max Planck Institute for Metabolism Research in Cologne shows how the reward system in the brain conveys judgements affected by one’s own desires. (October 22, 2018) Read the […]

Axios: How your brain works when you’re brave

Scientists have learned a lot about how our brains work in dangerous situations — and how they work in people who have learned to control their fears, the Wall Street Journal reports. Why it matters: If science can find ways to make us braver — not stupidly brave, just better able to face danger — […]

Newsweek: Brain architecture: Every cell acts like minicomputer processing information

Each cell in the human brain appears to have an inherent ability to process information, scientists have discovered. By looking at neurons taken directly from human brain tissue, researchers were able to make some of the first electrical recordings of individual cells, which could provide insight into our intelligence. (October 22, 2018) Read the full […]

NPR: Want to keep your brain sharp? Take care of your eyes and ears

By age 40, about 1 in 10 adults will experience some hearing loss. It happens so slowly and gradually, says audiologist Dina Rollins. “You don’t realize what you’re missing.” And even as it worsens, many people are in denial. By the time someone is convinced they have a hearing problem, age-related memory loss may have […]
