A national team of researchers led by investigators at the University of California, San Diego School of Medicine have developed a multidimensional set of brain measurements that, when taken together, can accurately assess a child’s age with 92 percent accuracy. “We have uncovered a ‘developmental clock’ within the brain — a biological signature of maturation […]

The greatest risk factor for Alzheimer’s disease (AD) is advancing age. By age 85, the likelihood of developing the dreaded neurological disorder is roughly 50 percent. But researchers at the University of California, San Diego School of Medicine say AD hits hardest among the “younger elderly” – people in their 60s and 70s – who show faster rates of brain tissue loss and cognitive decline than AD patients 80 years and older.
The phenomenon of highly superior autobiographical memory – first documented in 2006 by UCI neurobiologist James McGaugh and colleagues in a woman identified as “AJ” – has been profiled on CBS’s “60 Minutes” and in hundreds of other media outlets. UC Irvine scientists have discovered intriguing differences in the brains and mental processes of an extraordinary group of people with effortless autobiographical memory – in this people, they can easily recall every moment of their lives since about age 10.
Is attention-deficit/hyperactivity disorder (ADHD) due to a delay in brain development or the result of complete deviation from typical development? In the current issue of Biological Psychiatry, Dr. Philip Shaw and colleagues present evidence for delay based on a study by the National Institutes of Health.
UT Dallas researchers recently demonstrated how nerve stimulation paired with specific experiences, such as movements or sounds, can reorganize the brain. This technology could lead to new treatments for stroke, tinnitus, autism and other disorders. In a related paper, The University of Texas at Dallas neuroscientists showed that they could alter the speed at which the brain works in laboratory animals by pairing stimulation of the vagus nerve with fast or slow sounds.
In a study of high-functioning adolescents with an autism spectrum disorder, scientists using functional brain imaging have found reduced connectivity selectively affecting parts of the brain that form circuits supporting social behavior. The findings sharpen the focus of previous reports suggesting disruptions in connectivity across the brain in autism, and offer a target for future studies to search for the genes that shape the development of these circuits and how they become disrupted in the disorder.
You are headed out the door and you realize you do not have your car keys. After a few minutes of rifling through pockets, checking the seat cushions and scanning the coffee table, you find the familiar key ring and off you go. Easy enough, right?
Mayo Clinic researchers have found a novel way to monitor real-time chemical changes in the brains of patients undergoing deep brain stimulation (DBS). The groundbreaking insight will help physicians more effectively use DBS to treat brain disorders such as Parkinson’s disease, depression, and Tourette syndrome. Included in this report is a video summary of the research findings.
