New, Multi-Dimensional Brain Measurements Accurately Assess Child’s Age

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 […]

Highly Superior Autobiographical Memory Linked To Intriguing Brain Structure Differences

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.

Brain Imaging Shows That Social Brain Circuits Are Disrupted In Autism

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.

The Roadmap To Alzheimer’s Disease Begins – Initial Findings Indicate That Varying Brain Activity May Reduce The Risk

Activity lingers longer in certain areas of the brain in those with Alzheimer’s disease than it does in healthy people, Mayo Clinic researchers who created a map of the brain found. The results suggest varying brain activity may reduce the risk of Alzheimer’s disease. Included in this report is a video summary of the study results as well as a link to download a PDF of the original study.

Researchers Uncover Two Brain Signals Involved In How Humans Predict Other Peoples’ Decisions

Researchers at the RIKEN Brain Science Institute (BSI) in Japan have uncovered two brain signals in the human prefrontal cortex involved in how humans predict the decisions of other people. Their results suggest that the two signals, each located in distinct prefrontal circuits, strike a balance between expected and observed rewards and choices, which enables humans to predict the actions of people with different values than their own.
