Subtle surface deformities in a deep brain region vital for movement and learning have been linked to risks for attention deficit and other disorders among premature infants, according to a new study.

The study for the first time mapped minute differences in specific areas of the putamen, a kind of crossroads deep in the brain’s architecture where signals, including sensation and motor function, coalesce and connect with higher regions associated with more complex functions.

Injuries and deformities to the putamen have been linked to deficits in attention-based learning and executive function – deciding on appropriate action – among adolescents who had been born prematurely, according to the study, published online Wednesday in the journal PLOS One.

“It’s sort of a pathway,” said USC clinical pediatrician Dr. Douglas Vanderbilt, an author of the study. “These sub-cortical structures are where sensation and motor functions coalesce before they go to the association cortex, which is the higher brain structures. They’re essential because they’re the freeways that connect to those downtown areas. So if there’s problems with that, information is not going to be delivered.”
