Here is what I am reading today:
“As science has long suspected, overall brain size matters somewhat, accounting for about 6.7 percent of individual variation in intelligence. More recent research has pinpointed the brain’s lateral prefrontal cortex, a region just behind the temple, as a critical hub for high-level mental processing, with activity levels there predicting another 5 percent of variation in individual intelligence.
Now, new research from Washington University in St. Louis suggests that another 10 percent of individual differences in intelligence can be explained by the strength of neural pathways connecting the left lateral prefrontal cortex to the rest of the brain.
Published in the Journal of Neuroscience, the findings establish “global brain connectivity” as a new approach for understanding human intelligence.”
“The junior high and high school years are emotionally challenging even under the best of circumstances, but for adolescents with autism spectrum disorders (ASD), that time can be particularly painful. Lacking the social skills that enable them to interact successfully with their peers, these students are often ostracized and even bullied by their classmates.”
“Over the last 30 years, rates of obesity have doubled among adults and tripled among children. The new IOM report summarizes growing evidence that these increases have been driven by a complex interaction of changes in the environments in which we live — our schools, our workplaces, our communities, in the media and in our food and beverage systems.
While praising the IOM report’s scope and vision, Colleen L. Barry, PhD, MPP, associate professor of Health Policy and Management at the Johns Hopkins Bloomberg School of Public Health and lead author of “Are Americans Ready to Solve the Weight of the Nation?” says that it is critical to understand how the public thinks about the problem of obesity. “…
