The objectives of this research project are to: (1) examine the effect of pre- and neonatal exposure to metals on neurochemical changes and neurobehavioral outcomes in rats; and (2) explore the potential modifying effect of stress on metals neurotoxicity.
Progress on Project 4 has been hindered by the delay in getting the subcontract to the Massachusetts College of Pharmacy finalized. We have, however, recently received the behavioral chambers for the Fixed-Ratio Waiting for Reward paradigm and are working out the details of the software programming. The Repeated Acquisition and Performance Chamber for the other behavioral paradigm currently is being designed and built. We are validating the High Performance Liquid Chromatography (HPLC) assays for dopamine, its metabolites, and glutamate. We also are finalizing the details of the assay for 8-OH-2’-dG and validating the assay.
Pilot testing of animals should begin shortly. As soon as the subcontract is finalized, we will be able to purchase the autosampler for HPLC analyses. We anticipate significant progress in the months to come.
