Science News: This AI uses the same kind of brain wiring as mammals to navigate

An artificial intelligence that navigates its environment much like mammals do could help solve a mystery about our own internal GPS. Equipped with virtual versions of specialized brain nerve cells called grid cells, the AI could easily solve and plan new routes through virtual mazes. That performance, described online May 9 in Nature, suggests the […]

Medical Xpress: A new way to watch brain activity in action

It’s a neuroscientist’s dream: being able to track the millions of interactions among brain cells in animals that move about freely, behaving as they would under natural circumstances. New technology developed at The Rockefeller University represents a big step toward realizing that goal. (May 7, 2018) Read the full article here

Science Daily: Thank your brain for gratitude

A brain network that gives rise to feelings of gratitude has been uncovered in new research published in JNeurosci. The study could spur future investigations into how these “building blocks” transform social information into complex emotions. Previous neuroimaging research in which participants imagined themselves as survivors of the Holocaust who received food, shelter and clothing […]

News-Medical: Researchers create a biomaterial that can be used to study the brain

Researchers have created a new type of biomaterial that can support the growth of nerve cells, potentially opening up new possibilities for patients who have experienced a stroke or traumatic brain injury. Using self-assembling peptides, bioengineers have created scaffolds that can be used in tissue engineering and biomedicine. Amino acids are groups of carbon atoms […]

U.S. News & World Report: Even mild concussion tied to greater dementia risk later

Concussions, even those that are mild, more than double the risk for developing dementia down the road, new research suggests. The findings stem from an analysis that tracked concussions and dementia risk among nearly 360,000 military veterans. Study author Deborah Barnes noted that many of the younger vets in the study had experienced concussions while […]

Medical News Today: Pupillary reflex may predict autism

A new study suggests that the pupillary light reflex — or how the eye’s pupil responds to light — in infants might be an early sign of autism. Autism now affects about 1 in 59 children in the United States, which represents a significant increase from 6 years ago. Since autism can be quite difficult […]

New Atlas: How cholesterol in the brain may accelerate the onset of Alzheimer’s disease

A landmark study has revealed that cholesterol in the brain may play a fundamental role in catalyzing the formation of amyloid beta clusters, thought to be a central mechanism leading to the devastating degenerative symptoms of Alzheimer’s disease. An international team of researchers, led by the University of Cambridge, set out to uncover what causes […]

Entrepreneur: A brain surgeon’s tips for handling stress head-on

Most people at least try to avoid stress, especially when it comes to business and workplace conflicts. Even successful, high-profile business icons struggle with how to handle stress: Elon Musk recently admitted in a tweet reported on by CNBC that he faces “unrelenting stress.” That’s alarming to hear from such a famous and successful entrepreneur. […]

Medical Xpress: Unexpected discovery gives new model for studying brain networks

The same kind of neurons can have completely different wiring diagrams in the rat and mouse, as mice lack intercellular molecular channels known as gap junctions, researchers at Karolinska Institutet report in the scientific journal eLife. The unexpected discovery gives the researchers a new model for studying the role of gap junctions in the brain. […]
