Dr. Newland explores the behavioral impact of drugs and environmental contaminants that act on the brain.
He draws from the experimental analysis of behavior, environmental health, psychopharmacology, and especially quantitative models of behavior, to explore how the neural consequences of drug and toxicant exposure are expressed behaviorally.
Dr. Newland's research activity is focused on the application of basic research in behavior analysis to the examination of exposure to toxic substances or drugs that act on the nervous system. In particular he is examining experimental models of abnormal development. This includes the long-term effects of heavy metal exposure, including methylmercury, lead, and manganese, as well as behaviorally active drugs. He has worked with both human and animal models. At present his laboratory is examining the consequences of exposure, during gestation, to methylmercury, omega-3 fatty acids, and selenium (alone and in combination) on development and aging. These substances are thought to impair neural development by their presence (methylmercury) or absence (omega-3 fatty acids, selenium).
