The first-of-its-kind study reveals that if pregnant mothers use drugs, it alters the brain's functional organization in newborns, including arousal regulation.

According to psychologydictionary.org, arousal regulation refers to controlling of cognitive and physiological activation using natural or cognitive-behavioral methods.
"This study may inform new strategies aimed at early risk identification and intervention," said Dr. Karen Grewen, the study’s other corresponding author, associate professor of psychiatry, neurobiology and psychology at the University of North Carolina.
The study found disruptions in functional connectivity within part of the amygdala-prefrontal network.
In the study, 152 infants were given resting-state functional magnetic resonance imaging (rsfMRI) scans. Of these, 45 had prenatal exposure to cocaine, 43 had prenatal exposure to drugs other than cocaine, and 64 had no known prenatal drug exposure.
Alterations in the brain’s functional organization were found in both groups that had prenatal drug exposure. The group with prenatal cocaine exposure had additional alterations that the other drug control group did not have.
