Research efforts focus on (1) the characterization of toxicity of chemical warfare nerve agents and on identification of improved therapeutics against chemical warfare agent exposure and (2) characterization of animal models of post-traumatic stress disorder. In vivo studies are performed in rodents, using endpoints of behavior, physiology, biochemistry, and neuroanatomy to evaluate efficacy of candidate pretreatments and therapeutics against nerve agent-induced toxicity, and to characterize social stress models. Classes of compounds being evaluated for efficacy against nerve agent exposure include, but are not limited to steroid hormones, neuropeptides, antiglutamatergics, and anticholinergics. We are (1) performing risk assessment studies, (2) evaluating prophylactics and therapeutics for efficacy against toxic levels of nerve agent, (3) evaluating mechanisms of nerve agent-induced toxicity in rodents, and (4) performing kinetic studies to compare biochemical changes following different routes of exposure to nerve agents. Neurobehavioral assessments include measures of motor activity and function, cognitive performance, sensorimotor function, emotional memory, and measures of anxiety and depression. Telemetry is used to continuously measure EEG and evaluate seizures and alterations in circadian rhythms and will also be used to measure EKG and blood pressure. Molecular biology and histological techniques are used to evaluate neuropathology and mechanisms of toxicity.
