What the grant funds

The overall goal of this Funding Opportunity Announcement (FOA) is to identify, in animals, in vivo neurophysiological and behavioral measures for use as assays in the early screening phase of treatment development. The FOA will support efforts to optimize and evaluate measures of neurophysiological and behavioral processes that may serve as surrogate markers of neural processes of clinical interest based on available knowledge of the neurobiology of mental illnesses. The screening assays thus developed from this FOA are expected to build upon systems neurobiology and clinical neuroscience to enhance the scientific value of preclinical animal data contributing to a therapeutic development pipeline by assessing the impact of therapeutic targets and treatment candidates on neurobiological mechanisms of clinical relevance to mental illnesses.
