PROJECT SUMMARY/ABSTRACT The Diversity Supplement candidate will be trained in all aspects of manipulating the firing activity within the lateral hypothalamus - locus coeruleus/VTA microcircuit by Interluminescence, testing efficacy of activity- independent (Persist-Int) pre- to postsynaptic drive by electrophysiological recordings in vivo. The training includes stereotaxic injections of AAV, acute extracellular recordings and computational electrophysiological data analysis. The experimental approach will allow the candidate to assess the efficacy of Persist-Int within this experimental paradigm while building a solid conceptual and experimental foundation for her future activities in biomedical research. The training experiences the candidate will gain are critical for her understanding and interpretation of state-of- the-art neuroscience experiments. The training plan takes into consideration that the candidate is at the very beginning of her research training and ensures that the candidate will have an exceedingly strong background for entering the next phase of research training towards meeting her career goals. Her training will have ranged from hands-on experience in executing in vivo experiments for controlling neural activity to evaluating and interpreting the collected data. Therefore, this training in in vivo electrophysiology will not only significantly contribute to the parent grant but will specifically provide her the experience required to pursue her long-term interest in pursuing a career as a neuroscientist. The proposed training outlined in the application is ideal given the candidate’s career stage and future plans and is tailored to having the greatest impact within the shortest possible time. An established training strategy will foster the candidate’s ability to swiftly reach a level where she can independently approach new projects and will be an asset to any research lab where she continues her graduate training. The proposed supplement activities will increase the parent award’s overall impact within the original scope of award while at the same time advancing the training and career development of the candidate.
