The Retrosplenial Cortex (RSC) has a persistent role in the establishment of spatial and contextual memory, with also the connections between visuo-spatial association cortices. The RSC’s ability to form afferent and efferent connections with the Parahippocampal areas of the brain allow it to be another prime location in the brains of both rodents and humans where multiple cues are linked together in memory formation, storage and retrieval of Long Term Memories. Due to the high nature of memory formation and retrieval, the RSC has become a section of the brain that in recent years has been more heavily focused on for the research of Alzheimer’s and Dementia. The RSC has not been examined fully in previous studies with examination of the expression of the apolipoprotein E (APOE) gene along with other genetic and regulatory factors. There are 3 major alleles of the APOE gene (APOE2, APOE3, and APOE4), with APOE4 having the greatest risk for AD. In this research, I identify the relative connection between DEK the proto-oncogene and APOE3 and APOE4 in a rodent model, looking specifically at the RSC and how it affects spatial memory with an induced model of chronic stress.
