Ventral Hippocampal Input To The Medial Prefrontal Cortex Regulates Social Memory, Mary Leann Phillips

All ETDs from UAB

Both the ventral hippocampus (vHIP) and medial prefrontal cortex (mPFC) are active participants in the neural circuitry activated by social interaction, and are both necessary for certain aspects of social behavior. Additionally, synaptic projections from the ventral hippocampus (vHIP) to the medial prefrontal cortex (mPFC) are implicated in several neuropsychiatric disorders. Using the Mecp2 knockout (KO) mouse model of Rett syndrome, an autism-associated disorder with network level deficits in the vHIP and mPFC as well as aberrant social behavior, we strove to determine the role of vHIP-mPFC in social behavior. Here, we show that the vHIP-mPFC projection is hyperactive in …
