Reviewed by Emily Henderson, B.Sc.Aug 26 2021 Research conducted at the University of Kentucky College of Medicine suggests that higher intake of specific nutrients is associated with lower brain iron concentration and better cognitive performance in older adults. The study was recently published in the Neurobiology of Aging and highlights the important balance of non-heme iron for...

RUTGERS UNIVERSITY Older Chinese immigrants who adjust to their new cultural environment by learning the language, following the country’s media, and socializing with local residents can reduce the acculturation gap with their adult children and protect their cognitive function, according to a Rutgers study. The study, published in the journal Aging and Mental Health, is...
UNIVERSITY OF TSUKUBA Tsukuba, Japan – Although exercise is known to enhance cognitive function and improve mental health, the neurological mechanisms of this link are unknown. Now, researchers from Japan have found evidence of the missing link between aerobic fitness and cognitive function. In a study published in Medicine & Science in Sports & Exercise, researchers from the University of...
INDIANA UNIVERSITY IMAGE: RICHARD BETZEL A team of Indiana University neuroscientists has built a new model of human brain networks that sheds light on how the brain functions. The model offers a new tool for exploring individual differences in brain networks, which is critical to classifications of brain disorders and disease, as well as for...
by Indiana University This figure depicts the edge functional connectivity of the brain as a network. Every “point” represents coactivity between two regions of the brain, akin to a “conversation” in the brain. Points are connected according to one another when their conversations are similar.

What does each part of the brain do and why? Can we communicate with a patient in a coma? How does continual cell phone screen-time affect us? These are the kind of questions that Brian Arwari ponders every day. A cognitive psychologist by training, he leads the neurocognitive lab in the Department of Kinesiology and...
by University of Texas Medical Branch at Galveston More than 2.5 million people in the United States alone experience a traumatic brain injury, or TBI, each year. Some of these people are plagued by a seemingly unrelated cascade of health issues for years after their head injury, including fatigue, depression, anxiety, memory issues, and sleep...
