This presentation addresses the impact of prenatal exposure to a common neurotoxicant on brain structure and neuropsychological function in an inner-city cohort of minority children. The toxic chemical, an organophosphate insecticide (chlorpyrifos), has been banned for indoor residential use in the U.S. since 2001, but continues to have widespread application for agricultural purposes. Possible moncholinergic mechanisms involve disruption of neural cell development and neurotransmitter systems, including the formation and activity of synapses in different brain regions. This presentation examines the evidence for long-term effects of prenatal chlorpyrifos exposure on neuropsychological profiles and brain morphology as measured by MRI. (#29838)
