Study also suggests potential treatment
New research has found that a child's relationships may be a hidden casualty long after a head injury.
Neuroscientists at Brigham Young University studied a group of children three years after each had suffered a traumatic brain injury – most commonly from car accidents. The researchers found that lingering injury in a specific region of the brain predicted the health of the children's social lives.
"The thing that's hardest about brain injury is that someone can have significant difficulties but they still look okay," said Shawn Gale, a neuropsychologist at BYU. "But they have a harder time remembering things and focusing on things as well and that affects the way they interact with other people. Since they look fine, people don't cut them as much slack as they ought to."
Gale and Ph.D. student Ashley Levan authored a study to be published April 10 by the Journal of Head Trauma Rehabilitation, the leading publication in the field of rehabilitation.
The study compared the children's social lives and thinking skills with the thickness of the brain's outer layer in the frontal lobe. The brain measurements came from MRI scans and the social information was gathered from parents on a variety of dimensions, such as their children's participation in groups, number of friends and amount of time spent with friends.
A second finding from the new study suggests one potential way to help. The BYU scholars found that physical injury and social withdrawal are connected through something called "cognitive proficiency." Cognitive proficiency is the combination of short-term memory and the brain's processing speed.
"In social interactions we need to process the content of what a person is saying in addition to simultaneously processing nonverbal cues," Levan said. "We then have to hold that information in our working memory to be able to respond appropriately. If you disrupt working memory or processing speed it can result in difficulty with social interactions."
Separate studies on children with ADHD, which also affects the frontal lobes, show that therapy can improve working memory. Gale would like to explore in future research with BYU's MRI facility if improvements in working memory could "treat" the social difficulties brought on by head injuries.
"This is a preliminary study but we want to go into more of the details about why working memory and processing speed are associated with social functioning and how specific brain structures might be related to improve outcome," Gale said.

Using an ultra fast-scanning atomic force microscope, a team of researchers from the University of Basel has filmed “living” nuclear pore complexes at work for the first time. Nuclear pores are molecular machines that control the traffic entering or exiting the cell nucleus. In their article published in Nature Nanotechnology, the researchers explain how the passage of unwanted molecules is prevented by rapidly moving molecular “tentacles” inside the pore.

If a person pushes a broken-down car alone, there is a certain effect. If another person helps, the result is the sum of their efforts. If two micro-particles are pushing another microparticle, however, the resulting effect may not necessarily be the sum their efforts. A recent study published in Nature Communications, measured this odd effect that scientists call “many body.”
