This five-year, $548,445 project grant from the National Science Foundation's Biological Sciences program (CFDA 47.074) will fund research at Louisiana State University to investigate the functional significance of glutamate projections from the ventral tegmental area to the hippocampus and their role in novelty learning and context discrimination. Using optogenetic modulation and neural recording techniques in freely behaving mice, the research aims to determine how these neural circuits integrate working memory and context in the hippocampus, and their role in hippocampal pyramidal cell-interneuron synchrony. The work is expected to advance understanding of cell-specific projections within the ventral tegmental area-hippocampus loop and their function in novelty learning and context-dependent behaviors.
