Prenatal pesticide exposure linked to changes in teen's brain activity

Prenatal exposure to the organophosphate pesticides has been linked to poorer cognition and behavior problems in children. A new study is one of the first to use advanced brain imaging to reveal how exposure can actually change brain activity. Teenagers estimated to have higher levels of prenatal exposure to organophosphates showed altered brain activity compared to their peers while performing tasks that require executive control, the study found.
